Hooking my brother up with my 15" Fi Q (basic) and its being powered by a RD 1000.1D doing 1000 at 1 ohm. Looking to get an amp kit for him and I can't remember whether or not to use 4 gauge power wire or higher? Also, the amp has 30Ax3 fuses for a total of 90 amps so I'm assuming I need a 90 amp fuse for the power cable? Reason I'm asking is because the knukonceptz kit I was looking at comes with a 120 amp fuse. Just a few simple questions.

I was just wondering if 4 of these batteries will be good for a car audio system. 2,000 watts RMS? This is the only best battery that I can fine in my own town. I can't get XS Power or anything like that. They do sell Kinetik at this one place but they are marked up 50% higher then SonicElectronix & I don't want to mail order any car batteries. There Shuriken batteries at another store too. there marked up high like the Kinetik. I like to buy them in store, If anything gose wrong with them. I can just drive to the store & return it. These Nautilus AGM Deep Cycle batteries are in stock ready to buy. Motomaster Nautilus AGM Deep Cycle 12 volt Battery C$259.99 Brand …

I have a rockford fosgate t1500-1bdcp amp and a ascendant havoc sub wired to 1 ohm. My amp will get very hot even when the music is very quiet. Also when i turn up the volume loud my sub will make a popping sound. The gain is turned all the way down, and i also have a stock alternator. Any help will be appreciated.

just was wondering if i should by this capacitor i was looking at. So would a cap benefit me in a burping scenario? my car will be running 2 sundown 4500's and a sundown 100.4(mids) with a 275amp Mechman H.O. alt with 5 XS power 14 volt batteries. any opinions on the soundstream sc-40CA 40 farad ? http://www.woofersetc.com/p3257/SC40CA--Soundstream-40-Farad-Digital-Hybrid-Super-Capacitor.htm or http://www.woofersetc.com/p3784/SCC1--Lightning-Audio-50-Farad-Carbon-Capacitor.htm

I have someone wanting to sell me an interfire a700.4 4 channel amp for $75. Has anyone used this amp, or something close to it thats made by interfire? Do they do rated? Are they clean? All I have found is this... http://www.interfireaudio.com/download/interfire_catalog_2009.pdf

How do I know what to set my SSF to? The Fs of my sub is 36.4Hz Box is 2 cubes tuned to 38Hz FS of my truck is 37Hz I can give you any T/S params you need, or you can get them from here: http://www.mtx.com/caraudio/products/subwo...ta_T9512-44.pdf (PDF file, 693KB) A direct answer of what to set it to is fine, but I would like to know how to calculate it, or at least a "rule of thumb" to go by when setting the cutoff frequency.

I have heard a lot about welding supply and coppercableman on e-bay, what about wire and supply or electron beam (EB-flex) wire? Also I see that 1/0 welding wire in general is rated for 350 amps at 50 feet while 2/0 is rated for 400 amps at 50 feet. I don't expect more than a 20 foot run at most from my front to back battery so what size cable would you guys recommend for a Crescendo BC3500d at one ohm with a 300 amp external fuse rating? Lastly I notice there is an ultraflex cable available from welding supply (as well as directwireusa.com) that claims to contain 4x the strand count of the standard wire yet the amperage ratings are the same?

As the title says. Hmm, Anyone know anything on this Sony?

i did a test to see which amp was harder hitting i ran the Crossfire Vr 1000d @ 2ohm through my PaP 15" MOAB = 500watts i ran the PPi Dcx 1000d @ 2ohm through my PaP 15" MOAB = 500watts i set the gain on both amps @ 1/2 or center or Noon... all settings on HU were left as Daily, subs crossed to 100Hz & down / 0gain or flat the Crossfire was weak to say the least... had to crank the HU to 25 to get any thing to shake the PPi on the other hand was Dominant as i only got to 8 on the HU and noticed the stuff on my walls in my guradge was shaking @ 12 on the HU the bass was well above pounding... the Crossfire Vr 1000d got guess ill put it in my Girlfriends truck on a …

as the title says crescendo audio ccx65 vs Rockford Fosgate Power T1652-S thanks

I'm a little bit confused about how to wire the RCA's. They have basically 6 sets of preamp outputs with some labeled mid, highs but also some sets labeled positive and negative. The manual isn't too detailed about using the pro setup except to connect all of them. I am going to be running tweets and mids up front and mids in the back. Plus a sub(which it has 2 pairs of outputs to as well for some reason). I will post some pix if necessary. Thanks for any help you guys can provide. I'm trying to get this done tomorrow as i will be working til 10 pm tonight.

I may be buying a pretty much brand new DD m2b from a friend. I already have a Crescendo BC2000D. Would it be worth keeping the DD and selling my BC? Or just keep the BC and get the money from the DD?

if we bridge a stereo amp does the impedance of the amp change? does the amp being bridged change the final impedance to the subs? as an example would 2 4ohm SVC subs wired in parallel be seen as a 1ohm load by a bridged amp?

I just got my 12" H2 but I have spent to much funds lately. I still have to get my components and an amp for the components. I really wanted to get a 2500 amp but its not going to happen for now. So do you think I will be missing out a lot by getting a 1200 amp? I will be running it in a 1.5 cu ft sealed enclosure.

Orion Xtreme 1400.2 XTR does anybody know the quality of this any thanks.

So I have the LC2i LOC. It says to use a 1 to 2 amp fuse for the power. Is this really needed? Someone I spoke with told me they don't think its required because the fuse on main power should act as fuse. And if an issue occurred then it should pop the fuse on the main power line. Is that correct? Just wondering if I should go find a 1 amp fuses?

I recently sold my amp, m3a, looking for a new amp under $1000 and wanting brand new. The amps I am considering are a M3b and SAZ3500D V.2 but not sure why I would pick one over the other. From comparing the older models it seems the saz3500d v.1 produced more watts than the M3A so is the M3b comparable to the SAZ3500v.2? This amp will be powering a BTL N2 and will be wired down for .5 ohm on a 12volt system. Need some advise

So I just bought an Acura RSX-S, im wondering if I should use the bose system or buy a component set. To being, I have a some nice equipment in my room that I have NOT gotten to use yet.. sax 100.4 saz2500.1D DD 9515g DD 9512g I plan on getting some sort of double din TV with 4-5 volt rca outputs, decent crossover, and decent eq. I think I'll end up using the 2500 and the 9512g in the hatch.. but as far as my mids/highs.. Im not so sure what to do. The bose system sounds good, but I think it distorts past half on the volume knob. Maybe I will be able to tune it better with the aftermarket tv? Im not going for super sick SQ and Im not going for rattle my nuts out of my pa…

has any 1 ever used Lanzar's optidrive series amplifers? if so, what are the some helpful reviews on it. is it a good amp with low THD does this amp put out what its ratted? can you let me know if it is a overall good amp for subs will this thing get low and still stay warm?

I plan on buying an active compatible HU, but was wondering how setting crossover points on an HU works? If I am using external amplifiers, with crossover settings, do the settings on the HU ignore those, and just use the settings programed in the HU? Or would I have to set crossover settings on the amp which are equal to those on the HU? Specifically I will be running a US Amps AX-5600. Help is much appreciated. This will be my first active setup.

Finally got an email back from Fi, and they recommended an American Bass VFL amp. First time hearing about these. I've done some searching and they sound great. The problem I have is where to get these at a good price and from a respectable company/person. The prices on the net are all over the place. I was initially set on getting a Sundown amp, but now these. Any links would greatly help, I need a Christmas present for myself

I have a couple questions about wiring my system. 1. When wiring more than one battery where to put the fues? 2. I have a side post stock battery is there a way that I can put adapters on the stock battery to connect the ring terminals? One last question about the batteries....do I connect all positives to each other and all negatives to each other?

What is this thing worth in good shape used? Guy locally offered to trade me my Soundstream XXX4000d for one. Im just gonna turn around and sell it if its worth much.

Ok guys I have a 2010 tahoe with my stock alt and a DC 270 xp alt. They are both on a bracket, but what I really want to know is how to run my second alt at 18v. PLEASE be very detailed because I did not put the alt in and have very little experience with this sort of thing. Thanks ahead of time.
