I have an 01 tahoe with 2 15's kicker cvr dvc 4 ohm wired down to 1 ohm. Us amps xt 4000 1500rms@1ohm and a crunch 1400 4 channel and a 4 farad performance teknique power cap. red top under hood and db electrical ho alt. Have not did the big three yet. At idle my voltage drops to 13 or even 12 when bass really hits. Will the big three help with 0 gauge wire. Should I buy a powermaster D680 or D975 and get rid of the cap

alright, my girlfriends car has a rf 300.1 to a rf punch P2 12. single 4 ohm(not sure why the place let her buy that combo, 150Wx1@4ohm) I bought a new sub for her birthday, just a resonant engineering REX 12 dual 4. nothing special but it will be getting twice the power at least. it is a ~2.5 ft^3 ported box tuned to 28 I think it was, that I built for her a while back, and I still need to carpet it. RE I havent told her that I got the sub for her, and dont want to tell her. I planned on in the middle of the night going out and pulling the box, carpeting it, and dropping in the RE. obviously I wont be able to bump the system in the middle of the night. I want her to turn…

big thanks to rob. http://www.dcpowerinc.com/ Here are some pics of the alternator. goes in here more pics and video coming soon, just waiting on some terminals

Can anyone tell me anything about this amp? http://viewmorepics.myspace.com/index.cfm?...mageID=19074905 http://viewmorepics.myspace.com/index.cfm?...mageID=19075139

I bought a new Pioneer z110bt and have been messin with installing it into my 2006 Nissan Xterra SE. I keep getting this high pitched whine. The factory Rockford Fosgate system is still in, and I have the bypass harness' and everything is hooked up right but it still makes this high pitched whine noise. Keep in mind this is WITH the key off...........I am lost as to why its doing this........The whine is still present with the RCA's unplugged. Any ideas guys? J

Anyone out there know the rms on the American Bass vfl-175.1 OR has anyone tested one ?

Alright i'm running 4 Dual 4 ohm speakers aiming for 2 ohms. Theory #1: Wire two subs in parallel separate (yeilds 2ohms a sub). Then wire these together in parallel yeilding 1 ohm total for 2 speakers. Then, wire the other two subs the exact same way yeilding two sets of speakers ran down to 1 ohm per set. Now im running one amp. Then run these two sets together in series on the amp yeilding 2 ohms. Only question, wouldn't this i swap the polarity in one set of the speakers??????? Theory #2: Run each sub in series (yeildin 8 ohms a sub). Then run all of the subs in parallel at the amp. Yeilding 2 ohms. I think this is the correct way!! Im going to finish my box tom …

Does anyone have exp with PPI's PCX-4125? There is a pretty good deal on ebay right now for one and it would fit my needs pretty well for powering both my kodas and ID's cx62's. Any comments, thoughts about the amp? Just wondering if I should snag one or look elsewhere. thx

For my birthday, my girlfriend bought me a brand spanking new Eclipse 5425 HU. I chose to install it because I was ripping everything out in order to lay down wiring for new speakers and amp. And I just really like doing that stuff myself. The problem is this... Sometimes the display and buttons don't light up and are inoperative. The stereo still plays, but you can only adjust the volume level and change stations. You cant insert or eject a cd, change any functions, or even tilt the screen. Other times every thing works just fine and dandy like it should. There doesn't seem to be any patern to when it does this. I have triple checked my wiring and made sure th…

im running 2 saz 4500's to 2 fi btl's and i was wondering should i strap them or dont? what is the purpose of strapping?

anyone have any luck switching to a smaller alternator pulley? Were there any noticeable gains in output?

How do you turn off the demonstration mode???

ok, for setting gains with the DMM method, do i use 0dB tones, or can i get away with using, say -6dB or -3dB tones? I've heard recommendations for using as much as -6dB tone (that seems a little much to me) so i guess what I'm asking is how loud does most music get? does it regularly hit 0dB, or more like -3, -6, etc?

alright, i got 2 kinetik 1800s. I was originally just going to take out the stock battery and put one under the hood and the other in the back. But i just want to ask a few more knowledgeable people first, should i just leave the stock battery under my hood in the tundra and put both kinetiks in the back? thanks

What gauge size are the power supply connectors for the sax-1200d? thanks

So I have had my 12" Icon all but a month now and I feel like its time to get it an amplifier that will make it happy. Right now it is being powered from a JL Audio 500/1 and it seems to take it with pleasure. So far it has made a great addition to my Toyota Camry. What I will be doing is upgrading the power for the Icon and re-doing the front stage hopefully in the spring. Basically in the end of my other thread I mentioned a particular amplifier I am interested in and was hoping to maybe get some suggestions along the same lines as that one. The particular amplifier in question is a Boston Acoustics GT-2300. Seems to fit my needs and then some. What I am looking for in…

I just got my sundown 1200D and tomorrow my icon D2 from johnecon should be here. Any suggestions for subsonic and crossover settings?

I have been frustrated trying to track down the background noise on my headunit. Here is what I have: Headunit - Pioneer 9400bh Amp 1 - Kenwood 150.2 Amp 2 - Kicker 500.1 #1 The pioneer when playing a 0 bit track has pink noise from usb and cd. Kenwood amp is powering my front stage and the pioneer is for the back. Fader front and rear both produce the noise with and without both rcas. #2 So I reattached the original headunit and there is no noise with the 0 bit track cd. It is hooked up to just the rear speakers. I have changed the grounds on both amps, changed the ground on the headunit, done the pico fuse fix (wire wrap). I am at my wits end, please tell me if buying…

So I'm gonna do the wiring for my 4channel before I actually get it and the way my h/u kit is designed my h/u has to be bolted in...u can't just pull it out from the front. So can I plug in the rca's in the back of the h/u and not have them plugged into anything at the other end or does there have to be a connection? Or should I just do all the wiring and just not plug it in the h/u until there's a 4 channel I can plug it into

hi, i have been using my psp for music lately and the difference in volume from a cd and that is huge and i am wondering how can i go about making it louder? i figure i might be able to use a linedriver but then i got to thinkin that might mess stuff up since most are 8 volt line drivers so if a head unit only has 4 volts preamp i can see problems. so can only one shine some light on this. of btw i am getting a Alpine CDA-9885 ( i need a decently cheap but still a decent headunit right now.)

Whoops posted this in the subwoofer section by accident! Anyway help me out!!!!!! Crossfire vr 1000d???? Heard good things about it. Do not have any dealers near me to check one out. What do you guys think of this amp. I also have heard some good things about the nine 1. How are these two amps. I am looking for something to power either a tc2000, rl-p or oz matrix elite single sealed 15. I have heard these where both all around solid amps. I do not buy from shady internet sites so any suggestions please have them be authorized or through woofers etc. Thanks for the help guys! ps: I plan to upgrade amps later on. I want solid all around amps. Something the high end guys ca…

was thinking about getting one in a little while. I dont want to spend too much, but want something reliable. how long would it take to get familiar with one? any suggestions?

could you use 6 volt batteries in car audio? I know if you wire two in series it would make 12 volts, but then how can you get it to co exist with your 12 volt startying battery? 6 volt batteries have alot better reserve capacity

Need a little help. Finally got everything wired up and in the car. Ran all my wiring, hooked up my batcaps, grounded everything and I have power to everything. Only problem is that I can't get any sound out of my Sub or Component speakers that are wired up to the amps. Nothing is in protect mode or anything. Are my RCA's possibly bad, or is the headunit just not sending out a signal? I got about 5 seconds of sound out of the sub and components when I first turned it on, now nothing works. No fuses are blown or anything. I need help please!! Any replies are appreciated. Jeff
