160's is bonkers, and oh by the way, that's a 160 with out the subs having to be reconed.

This is a custom Infinite Baffle GCON from SSA. I do not really need to sell it but things have changed and I want to sell it to someone who will actually use it. It is brand new and only taken out of the box for pictures. D2 voice coils. I have two available $200 shipped each

A used creacendo 3500 or sundown 3500 would meet your goals and budget.

SSA is an authorized xs dealer so they should have whatever warranty xs has on their batteries.

There are a ton of build logs on DIYMA for these cars. Go take a look and you may find some great ideas.

Subaru front

Um, it is at a shop. 100' will go REALLY quick. I'd step up to the bigger rolls.

bro hurry the efff up...also where did you post photos of the horns at??? can't find them

And I know, nice pretty shopping bags. Wife keeps buying flowery ones. I like the black ones. Anything to make me feel gay or look taken in the store I guess.

This and a pair of she's were frolicking in the yard yesterday. Gobbled up in a tree all morning the next day too. Funny since my 1yr old doesn't really talk, but he had a hoot gobbling.

Thanks . Gotta have this baby done by the end of saturday.. Still lots of work to do

Don't forget to do block body lifts and not compensate in braking power for the massive increase in unsprung weight. What, you expect me to make major modifications to my vehicle AND take proper safety precautions ??? That's absurd !! However, talking to my dad last night....apparently the front tires on my car were the tires that originally came on it, and it's a '94.

They aren't ignoring emails, they receive an insane amount of emails.

Well from February it has been 2 months for me, but Nick and Scott are getting things back to normal lead times.

No problem bro.

thanks man.

I ordered a Zcon and have received a tracking number but when I check tracking it just tells me it was created but has not arrived to a ups deilivery site. Is this normal with a purchase from SSA? I just got excited since when I ordered it said 21 days + for delivery. Can I get this cleared up? Super pumped first SSA sub purchase.

Posting again about my recone. Just bord and wanting it bad lol. Sucks it takes this long cause Iv had a few people iv built boxes for want ssa subs after hearing mine but wouldnt order any cause how long its taking me just to get a recone.. I know its hard to keep up with orders but I know there would be a lot more subs sold if there was less time to wait

Equal amount to power as to ground.

Really don't need that much power was looking for something moderate size the 3000d is just to big of a amp in "size" for my application needs. Thanks though

That is a very good question for which I can not answer.

Absolutely. Flush mount is the ONLY method for mounting a driver IMO. While this "can" be done with the baffles separate it is more work and has a larger chance of failure. Glue them up first!

with the zcons we clamped 9k out of the pair but that was rising to 5ohm straped at that frequency. will have to clamp it agian with the new subs (different starting impedence) did make some pillars for it today as well. also got over the 60 mark.

Well this thread escalated quickly. OP all i can say is there are some amazing guys on here when it comes to advice and help. detail on your box as in dimensions of it and port are infinitely more helpful than pics. hang with it and this is a great place to learn. i can see both sides of the respect argument but as stated nothing here is sugar coated. tho i would hesitate to say your install sucks before seeing it, the guys here know what that sub is capable of in an ideal install, so when u say it fckin sucks, we automatically assume its install over equipment. hope that makes sense. no offenses meant to anyone here including OP

Slow your roll my friends. If you can't take constructive criticism then you are in the wrong place. We don't sugar coat the truth, if you disagree with something that someone said then you need to state that and explain your reasoning. Don't resort to name calling or you will be gone quickly.

The below formulas I use in mathcad to do calculations. You can do them by hand to calculate power in a given box. [Last modified 07-Feb-07] SPEAKER DESIGN EQUATIONS 3.6 Bill McFadden 1993 [[email protected]] The most current version of this file can be found at: http://www.rdrop.com/users/billmc 1. Introduction This is a library of equations for designing ported and closed-box speaker enclosures. The equations were taken from speaker design books and technical papers by Richard Small and Neville Thiele (see references in tutorial section). They are designed for un-stuffed enclosures. Refer to the references for more information on stuffing. The equations are intended to be used with the HP48GX/SX multiple equation solver but can also be run with the solver built into the HP48SX. The binaries are provided in uu-encoded and ->ASC form. An RPL version is also provided, but does not include the binary variable Mpar needed by the multiple equation solver. The initial default speaker parameters are for the Eminence 18029 18" driver. I welcome any comments or refinements. 2. Variables The main directory is called SPKR and consists of two subdirectories: CB Closed Box Design PORTED Ported Box Design Running the multiple equation solver from either subdirectory will produce a menu of variables: Vas Volume of air having same acoustic compliance as driver suspension Qts Total driver Q at Fs Fs Resonant frequency of driver PEmax Thermally-limited maximum RMS input power SPL Efficiency of driver in dB SPL at 1W/1m Dia Diameter of driver xmax Peak displacement limit of driver diaphragm (1/2 of "throw") Vb Inside volume of enclosure Fb Resonance frequency of enclosure F3dB Half-power (-3 dB) frequency of loudspeaker system response Fmax Upper frequency limit of driver's piston range dBpeak Maximum peak or dip of loudspeaker system response Par Estimated displacement-limited acoustic power rating Per Estimated displacement-limited electrical power rating \Gno Driver efficiency (\Gn is Greek character eta) PeakSPL Thermally-limited RMS sound pressure level in passband Sd Estimated effective projected surface area of driver diaphragm Vd Peak displacement volume of driver diaphragm K1 Power rating constant K2 SPL rating constant The following additional variables are defined for the closed box case: Qb Total Q of system at Fb Amax Maximum amplitude of loudspeaker frequency response Vr Ratio of Vas to Vb Qr Ratio of Qb to Qts and Fb to Fs The following additional variables are defined for the ported box case: Dmin Minimum diameter of tubular vent to prevent excessive vent noise Dv Diameter of tubular vent Lv Length of tubular vent For the ported box case, the following apply: 1. Fb is the tuning frequency for the vent. 2. To use a square vent, enter the vent width times 1.13 or [2/SQRT(pi)] for Dv. 3. Design When designing a loudspeaker, two approaches may be followed. The easiest is to select a driver and design an enclosure for it. The other is to design the enclosure first, then select or build a driver that matches it. The choice between a closed box and ported box depends on several factors. Closed-box systems are the easiest to design and build and have the advantages of smaller box size, good low-frequency power handling, and superior transient response. Ported-box systems are more difficult to design because they require precise duct tuning. However, ported boxes have the advantages of superior bass response, good efficiency, and superior peak power handling in the passband. 3.1 Closed-Box Systems Closed-box systems are designed around one variable, box volume. Box volume is a function of the driver parameters and the system Q, Qb. To design a system with minimum peak or droop in the passband, Qb must be 0.707. The designer has the choice of setting Qb and solving for the box volume, or setting the box volume and solving for Qb. There is also the choice of assigning values to both of these variables and solving for one of the driver parameters. To design a closed-box system, enter the CB subdirectory and run the multiple equation solver. Alternatively, run the built-in HP48SX solver and select DESIGN.EQ as the current equation. Choose one of the following variables to solve for and assign values to the rest: Vas, Qts, Fs, SPL, Dia, xmax, Qb, and Vb. If you don't have all of the parameters available, purge the ones you don't know, so they'll be undefined and the solver won't attempt to use them. At a minimum, you will need to supply all but one of Vas, Qts, Fs, Qb, and Vb. Next, press <- ALL in the multiple equation solver to solve for all the unknowns. If using the built-in HP48SX solver, you will need to solve for each unknown individually, using NXEQ to sequence through the equations. 3.2 Ported-Box Systems Ported-box systems are a little more difficult than closed box systems because there is an additional variable, tuning frequency. The optimum tuning frequency depends on the driver parameters and box volume. To design a ported-box system, enter the PORTED subdirectory. Run the equation solver of your choice as described above and enter the driver parameters. Notice there is no Qb variable. At this point solving for the unknowns will automatically create a system with optimum passband response. Alternatively, you can specify values for Vb and/or Fb to see what effect they have on the system response. To find the minimum recommended diameter of a tubular vent for the enclosure, solve for Dmin. This is smallest diameter permissible to keep the air velocity below 5% of the speed of sound. Higher velocities can produce audible noise. To calculate the vent dimensions, enter either of Dv and Lv and solve for the other, keeping in mind the minimum recommended value of Dv. 3.3 Cabinet Design In the CST menu of the CB and PORTED subdirectories is a key labeled BCALC. Pressing this key runs the box calculator program. Don't run it directly from the SPKR subdirectory, or it will not work properly. The program is rather crude, and does not handle dual woofers, but is adequate for most designs. It works as illustrated by modeling the driver as a segment of a solid cone: _____ /| ^ / | | / | | / | | _____ / | | ^ | | | | | | | Rdia | | Dia | | | | __v__ | | | \ | | | \ | | | \ | | | \ | | | \| __v__ | | | |<-Depth->| | | To use, enter the driver's depth (distance from front of driver to back of magnet) and press DEPTH. Enter the rear (magnet) diameter of the driver and press RDIA. If you want the program to account for any extra volume taken up by bracing and other drivers, enter this volume and press XVOL. The program uses the driver's diameter as entered previously in the equation solver. The dimensions default to English units. The program will only accept real numbers as input; unit objects will cause an error. (I said it was crude.) To change units, store a value containing the new unit by typing 'name' STO, where name is one of Depth, Rdia, or Xvol. The units of the results should make sense based on the units of the data, but I won't guarantee it. You can also change the ratio of Height:Width:Depth used in the box calculation by pressing GOLD, 1.25:1, or CUST. GOLD selects the golden mean, 1.62:1:0.62 ((sqrt(5)+1)/2), which is the most common ratio. 1.25:1 selects another common ratio, 1.25:1:0.8. If you wish to use a custom ratio, enter it and press CUST. Each time you change a parameter using a menu key, the results will be recalculated and redisplayed. The display shows, from top to bottom, the driver's front diameter, the driver's rear diameter, the driver's depth, the extra volume taken up by other objects inside the cabinet, the total internal volume of the cabinet (including driver and extra volume), the ratio used to calculate the box dimensions, and the inside height, width, and depth of the cabinet. FIX 2 is the best display format to use with the default units. 3.4 Equalization of Closed-Box Systems There is a subdirectory in CB called EQUALIZER that will find the component values for an active equalizer that can extend F3dB of any closed box system to any desired lower limit (at the expense of efficiency and power handling--watch out!) See [11] for theory and circuit details. First, use the equation solver in the CB subdirectory to solve for the system as shown above. Next, enter the EQUALIZER subdirectory. Store the new desired cutoff frequency into F3dB, and press CIRCUIT. The component values will appear in the display. The values of R, C, N are chosen by the user to make the remaining component values realistic (see [11]). 4. Analysis 4.1 Frequency Response The equation solver generates three values related to frequency response, F3dB, Fmax, and dBpeak. F3dB is the frequency at which the acoustic output power of the speaker drops by half. Below this frequency, the response will drop 12 dB per octave for the closed box and 24 dB per octave for the ported box. Fmax is the upper limit of the driver's piston range. Piston range is defined as the range of frequencies for which the wavelength of sound is greater than the circumference of the driver's diaphragm. In this range, the driver's output is non-directional. Since this package models the driver as a piston, it is important to note that the equations are only accurate up to Fmax. In addition, because it is difficult to predict the driver's high-frequency behavior, it is a good idea to cross over to a smaller driver at or below Fmax. dBpeak is the magnitude of the frequency response peak or dip. For an optimal design, this value will be zero. To examine the frequency response in detail, enter the CB or PORTED subdirectory and run the plotter or built-in HP48SX solver. Select FREQresp from the equations catalog. F is the frequency variable, and dBmag is the response at that frequency. Using the solver you can solve for one in terms of the other. 4.2 Power Handling The equation solver generates power ratings called Par and Per. Par is the displacement-limited acoustic power rating. For the closed box, Par is the worst-case value for wide-band signals (all the way down to DC). For the ported box, it is an estimate based on the characteristics of musical signals. Per is the displacement-limited electrical RMS power rating based on Par. Because displacement-limited power handling is actually a function of frequency, the values of Par and Per only give small part of the picture. To examine power handling in detail, enter the CB or PORTED subdirectory and run the plotter or built-in HP48SX solver. Select POWresp from the equations catalog. F is the frequency variable, and Pmax is the maximum electrical input power at that frequency. Pmax is plotted first, followed by PEmax, the manufacturer's thermal RMS power rating. At some frequencies, Pmax will exceed PEmax. As frequency increases, Pmax can reach thousands of watts. Exceeding PEmax is permissible for short durations, but under no circumstances should you exceed Pmax even briefly or the driver may be physically damaged. Because Pmax is calculated with sine waves in mind, the peak power rating at a given frequency will be 2*Pmax. Using the ISECT function of the plotter, it is possible to determine the frequency range(s) over which it is safe to apply the full rated thermal power, PEmax, without damage from excessive displacement. Just place the cursor near the intersection of the curves and press ISECT in the FCN sub-menu. In the same manner, you can also use ISECT to find frequencies where the curves approach one another but don't touch. 4.3 Sound Pressure Level The equation solver generates a value for maximum SPL called PeakSPL. This is the maximum RMS output level of the system in the passband when driven by the thermally-limited maximum input power, PEmax. Like power handling, displacement-limited SPL is a function of frequency. To examine displacement-limited SPL in detail, enter the CB or PORTED subdirectory and run the plotter or built-in HP48SX solver. Select SPLresp from the equations catalog. F is the frequency variable and SPLmax is the displacement-limited SPL at that frequency. SPLmax is plotted first, followed by the thermally-limited RMS sound pressure level. As before, for frequencies where SPLmax exceeds the thermally-limited SPL, the maximum SPL may be limited to a value in between, depending on the peak-to-average power ratio of the input signal. Again, ISECT can be used to find the frequency or frequencies at which the displacement- and thermally-limited SPL ratings are equal. 4.4 Analysis of Equalized Closed-Box System Using an equalizer to extend the bass response of a closed-box system does not come without costs. For each octave of bass extension, a 12 dB boost is necessary (and requires 16 times as much power). To evaluate these costs, two equations are provided in the EQUALIZER subdirectory: FREQresp and POWresp. These function like their counterparts in the CB and PORTED subdirectories, but take into account the effects of the equalizer. Because I took the equations right out of the article [11] without any optimization for speed, these equations run very slowly. However, I left out the units wherever possible so the equations would run faster. FREQresp calculates the response of the equalizer, rather than the system, to give you an idea of the amount of boost required to equalize the system. The greatest boost occurs at the new F3dB. POWresp calculates the equivalent power handling of the system. At each frequency, Pmax is reduced by the amount of boost the equalizer provides. This is useful to see what the power handling of an equivalent, un-equalized system would be. There is no equation for maximum SPL vs. frequency because it is the same as the un-equalized system. 5. Design Equations Here are the equations used by the speaker design library. All values have SI (mks) units. ^ denotes exponentiation. LOG() is base 10. 5.1 Constants pi = 3.14159265359 c = speed of sound in air (345 m/s) Ro = density of air (1.18 kg/m^3) 5.2 Closed-Box Systems Vb = Vas/Vr Fb = Qr*Fs F3dB = Qr*Fs*((1/Qb^2-2+((1/Qb^2-2)^2+4)^0.5)/2)^0.5 Fmax = c/(pi*0.83*Dia) dBpeak = 20*LOG(Amax) Par = K1/Amax^2 Per = Par/(\Gno) \Gno = 10^((SPL-112)/10) PeakSPL = SPL+10*LOG(PEmax) Sd = pi*(Dia*0.83)^2/4 Vd = Sd*xmax Amax = Qb^2/(Qb^2-0.25)^0.5 for Qb >(1/2)^0.5, 1 otherwise K1 = (4*pi^3*Ro/c)*Fb^4*Vd^2 K2 = 112+10*LOG(K1) Vr = Qr^2-1 Qr = (1/Qts)/(1/Qb-0.1) Frequency-dependent equations: Fr = (F/Fb)^2 dBmag = 10*LOG(Fr^2/((Fr-1)^2+Fr/Qb^2)) Pmax = K1*((Fr-1)^2+(Fr/Qb^2))/(\Gno) SPLmax = K2+40*LOG(F/Fb) Thermally-limited RMS SPL = PeakSPL+dBmag 5.3 Ported Box Systems Vb = 20*Qts^3.3*Vas Fb = (Vas/Vb)^0.31*Fs F3dB = (Vas/Vb)^0.44*Fs Fmax = c/(pi*0.83*Dia) dBpeak = 20*LOG(Qts*(Vas/Vb)^0.3/0.4) Par = 3*F3dB^4*Vd^2 Per = Par/(\Gno) \Gno = 10^((SPL-112)/10) PeakSPL = SPL+10*LOG(PEmax) Dmin = (Fb*Vd)^0.5 Lv = 2362*Dv^2/(Fb^2*Vb)-0.73*Dv Sd = pi*(Dia*0.83)^2/4 Vd = Sd*xmax K1 = (4*pi^3*Ro/c)*Fs^4*Vd^2 K2 = 112+10*LOG(K1) Frequency-dependent equations: Fn2 = (F/Fs)^2 Fn4 = Fn2^2 A = (Fb/Fs)^2 B = A/Qts+Fb/(7*Fs) C = 1+A+(Vas/Vb)+Fb/(7*Fs*Qts) D = 1/Qts+Fb/(7*Fs) E = (97/49)*A dBmag = 10*LOG(Fn4^2/((Fn4-C*Fn2+A)^2+Fn2*(D*Fn2-B)^2)) Pmax = (K1/\Gno)*((Fn4-C*Fn2+A)^2+Fn2*(D*Fn2-B)^2)/(Fn4-E*Fn2+A^2) SPLmax = K2+10*LOG(Fn4^2/(Fn4-E*Fn2+A^2)) Thermally-limited RMS SPL = PeakSPL+dBmag

Maybe this will clear things up for the funky pup. 1 watt to a funky pup is like 10000000 watts to a DD Z. These are Chuck Norris’s choice, not for bass, but to replace the engines in all his WalkerTexasRangerMobile’s… 1 funky pup = 500 horses, 2 funky pups = 1500 horses, 3 funky pups = time travel. There was never an atomic bomb, there was 4 funky pups in a .25″ particle board sealed box. They stopped making funky pups because the warehouse they were stored was quickly shifting the earth’s magnetic field. As a result, most of the world’s funky pups are now stored in a secret underground warehouse below Santa Claus’s Elf sweatshop. Its not certain what exactly makes the funky pup’s so much better than everything that ever existed, but it is absolutely certain – THESE ARE THE BEST W00FERS EVER MADE BY MAN OR SPACE MONKEY!

One bass note from a funky pup can level a whole city. You have to have a permit to own one since they are considered weapons of mass destruction.

i thought by "modified" that something was done internally to the amps but nice looking install there man

Couple more pics, of these beauties.

Received one of the subs, this thing is a beautiful beast.

ohh how i would love to get my hands on a 6 door!!

good question.. umm its around 41 htz

i wanna know who it was!! i plan on putting in a good word for you .. not sure how much good it will do but. i spoke with jon quickly today in email then had to get back to work.

that may help! but this my daily driver and these are my others, so i may be able to make it work!

i was rolling over a chicken truck.. heres a shot from the local paper but thats a whole other topic i never update anymore

thank you .. i think that point is lost on alot of people. thanks again !

thank you .. i think that point is lost on alot of people. thanks again ! Especially in the trunk you have. i know you rememeber exactly how hard it is to make these cars loud, you had the exact same trunk. thanks bro

heres a vid of the front stage, my phone cracks up at moments... because its sooo loud.. but i hope you can hear the quality

please tell me more random person who knows nothing about me and johns internet fued

a memeber has sausage fingers and cannot type correctly

yea i got banned for making a support obama gun control thread when one of the admin is a real hill billy gun nut they have alot of gun threads and maybe you're onto something the car audio forum tough guys are all old and way past any kind of beginner stuff so far past that they have no patience at all and by old i mean over 25 this sucks for us who are in the middle of nowhere and have barely any car audio help because these guys who are on forum all day have attitudes usually personally i cannot believe they allow the skar bashing here when it is sold in ssa store

troll?

if u did that next 2 some people who are not car audio heads they might think u got the voodoo magiks

yea electrical is strong were going towards 1ohm and i would be terrified that anything i ever bought from u would come with a punch in the face
