Subwoofers / Speakers

Hello all, I'm in the process of designing a box for my 99 grand Marquis. One zv4 15 d1 running of a bc3500 @2 ohm for now, until I get a new alternator soon, then will do.5 ohm. The two options I have with the space available would be 3.5 cubes net with 60"port volume and 36.5"length. This would give me ~32 hertz...I think. Or 3.75 cubes net with 38.5" port length to give me ~30 hertz. So my question is, if I go with the bigger box with the lower tuning, will I lose allot of output in the top end? The sub will be firing up with the port firing back. I also cut out behind the arm rest and took the speakers out rear deck to let more air flow Through

I got my fiberglass box done sorta. It is done to the point that I can get an internal volume. I packed about 15 gallons of packing peanuts in there. That gives me roughly 2 cubic feet. I know peanuts are not the most accurate, but that seemed like the easiest way. So anywho, I have about 1200w to throw at a Magnum that I am gonna get. Should I go ahead and put something in there to take up some space or let it ride and see how it goes? Then make it smaller if need be? Do you trust the peanut method? I don't want to buy a bunch of sand and then have to vacuum it out. What do you guys think? Thanks - Jim

I am looking at doing a blowthrough in my truck (yeah I know...its going to be expensive and a lot of work.) I'm not sure on the subs I want to run yet though. I'm looking at either 2 BTL's or 2 RD audio Alpha V.2. The sizes I'm looking at are either 18s or 15s. I want it to be loud at low hertz but I also want it to HIT hard and not just be loud with no punch to the bass. I have 4 Crossfire VR-1000D amps (putting out probably right at 4000 watts but will be more with the Big 3 and more batterys). which would fit what i'm looking for better?

Looking for thoughts on specs. I don't know a lot about T/S parameters and all, so looking for some insight. Leaving out brand and model for unbiased opinions. Thanks for any input. 1800 watts power handling • 800 Watts RMS • 200 oz. magnet • 2” BASV voice coil • SPL 91 dB • Fs: 36 Hz • Vas: 1.91 cu.ft. • Qms: 5.71 • Qes: 0.502 • Qts: 0.462 • Xmax: 0.4" • Sealed box: 1.2 cu. Ft. • Ported box: 2 cu.. Ft. • Tuning: 40Hz • Port Size: 4”(dia)x8.75”(length) • # of ports:1 • Mounting Depth: 6.25”

how safe would i be overpowering the mj-18 from mach 5 by 200wrms. what would be a safe amount?

Ok guys,first of all hello to everyone,im new here and sorry in advance for my english since it is not my main language,and for my ignorance about Sub's,Boxes ,and similar I am getting myself a 15" MB Quart Reference series RWE 352 subwoofer : (Source:Google ) It's 700w rms,1400 max,15",and im getting it very cheap from a friend,its almost brand new ^^ Problem is,i asked couple of guys,and saw on net that its recomended for this Sub to go in Sealed box 50 liters~....I already have a 300w RMS 10" Radical Audio subwoofer in a 26l sealed box,and ...weeell im not satisfied,i mean,its clean,fast precise bass,but just aint louuuuuud :/ So im kinda concerned how will it b…

So according to 12volt subwoofer wiring diagram I can wire two 2ohm DVC subwoofers to either 0.5 ohm OR 2ohm I can also wire only ONE of those subwoofers to 1ohm My question is, if I want to stick to 1ohm using those two 2ohm DVC subwoofers Can I just wire EACH sub to 1ohm, then run them to the amp each SEPARATELY from each other so that I keep 1ohm resistance? I have a Sundown 2000D

more power??

Hey guys, I am starting to save up some money to put into a system for my car and I am trying to decide on subs. Ive never had a big power setup before but I wanted to take a shot at it. My car is a 2002 hyundai XG350L. I want to do the setup to either have the port going thorugh a skipass or ported through the rear deck. I want to seal the box from the trunk to maximize potential. My original thoughts were to go with 2 12" xcons. But now that I've been starting to shop around im thinking that a single 15 might work better. Im really having a tough time deciding because 12's and a single 15" xcon would both be good setups. I know that there is a major power difference bet…

i need some help im planning on buying a 18 fi bl sub in the next couple days and im going to run it off a hifonics 1606d and i was wondering if i should go with a dual 1 ohm or dual 2 ohm?......

i have one type r running at 2 ohms at 500 rms....its in a ported box with the sub facing the inside of the car with the seats down....can anyone give me any suggestions to make it louder or just anything to make it better

i got 50' (overkill but i got it cheap) of speaker wire for my new components. i ran my power on the left and rca's on the right. which side sould i run the speaker wire on? does anyone ever leave the crossovers close to the amp so they dont get damaged? it would require me to run x2 wire tho... my components are pg 6.5" rsd's. amp is kx250.2 (mounted behind rear seat)

I saw this post a while ago and there's something I've been wondering. I would say that I personally think the Xcon could take the Havoc ported. However, from what I understand the Havoc's get suprisingly loud sealed. How are the Xcons sealed? Comparing the AA Havoc 15 Vs. Xcon 15 sealed, either powered off a Sundown 1500 watt in 3 - 3.5 cubes sealed.

I got the CDT's 62 comps and one of the woofers has some tinsel lead slap. I was going to put some small feltish sort of pads on there to prevent this. Do you think it would affect the woofer to the point where it would change the drivers ability to to play?

Does anyone know the gap measurments of the older MJ motor?

will they ever be Components again? jamie

How do these compare SQ and SPL wise?? I'm waiting to hear from a guy about a used RL-i 12" but also there's a local Treo dealer who said he'd sell me a TSX 12"D2 for $150 new w/3 yr warranty. It seems the 2 are fairly close in rms power, the SS being from 300-500 rms (I think) and the Treo being around 400rms (claimed it's underrated)... I imagine that both have more than adequate sound quality, but what about output? Any experience w/the Treo line? The dealer mentioned how the Treo is a 'unique design that makes it louder than it should be', take that for what you will. I'm limited on power (~300-400w rms) so I just want to make the most of what I buy and have some…

Hi guys, My Durango has 6.5's upfront with factory 1 inch tweets and 6.5''s in rear. My plan was to put new comp set up front and a midbass spkr, in rear, but after reading some peoples posts they say rear spkrs. won't be heard anyway. Is this true? If so instead of a 4 channel amp do I just run a 2 ch. and wire it to the spkrs and tweets or just the spkrs and run the tweets off the radio? Thanks for your help.

Hi all, As per my newbies post, I've been hanging around for some time, and have now registered to enjoy the full support and knowledge of the SSA members! The sub and box size are not optional here, that's all I have to play with. For power I have 1400 @ 1 Ohm, 625 @ 2 Ohms or 312 @ 4 Ohms. I was dead set on an Audiopulse EPIC 8, but have not been able to find one for love or money! So now I have a real dilemma... simply put, which sub should I buy? I am looking ultimately for SQ, but do want it to get loud whilst retaining that SQ. I have looked at the SoundSplinter, TREO SSi, MA Audio, Elemental Designs, Digital Designs, Image Dynamics, Eclipse and RE to name but a few…

Im looking for two 10" Incriminator Audio 187's. If anyone has any leads to them please let me know. As we all know the Lethal Injection series took them over so they are not made anymore. Thanks

Hi, im having trouble deciding what to tune my box to. the box is going to be about 3.1 cubic feet after the displacement of the subs, i was wondering how many 4 inch aero ports i would need, and what to tune the box to. if i can get some peoples input it would be greatly appreciated.

Alright, as the topic says, I'm looking for a component set for my Thunderbird. I currently have a pair of Infinity Kappa coaxial speakers in it. They are 6x8 and that is what my bird is designed for. I'm looking to spend no more that $250 on a set. They will be powered by a RF P400.4 amp. I have no problem fabricating some MDF size reducers if necessary. This is my only place of reference really, and I trust most all of your opinions. No one around my area has any type of aftermarket stereo, so I really can't demo anyone. Over all what I'm looking for is something that can get loud, but still sound clean. Any suggestions or previous experience with a certain p…

Net Volume: 3.32 cubic feet Tuning Frequency: 36 Hz Port Width: 2.5 inches Port Area: 36.25 Square Inches Port Length: 17.75 inches Will this box work for two 12" lvl3 with 2 ohm DVC's? Than you in advance for your help Z

I recently burnt one of the leads on my sub. is soldering the wires back together the best way to fix it? if not what is the best way?

Well here's the story, I purchased this sub off my cousin who said that it was originally a RE 18 that he blew then he sent it to FI to be rebuilt with soft parts(not sure what this is). I then purchased a SAE 1200d to power it. Once I got everything installed I had no sound out of the sub, so I started troubleshooting the best of my abilities. I still couldn't get it workin so I took it to a audio shop who said he tested the system and it was the sub that was bad, he was unable to tell me why. I'm not sure what he did to test it so I hooked up a speaker I had layin around and it worked. After looking through some threads on here I found a topic on some things I can do t…
