I'm getting some 8 gauge wire for speaker wire for my BL 15 that's coming, and my friend's dad, (who is an electrician), said that there were some rather flexible jumper cables available at Menard's that would suit my needs. Now I've always been told wire is wire and copper is copper, but some of the 4 gauge welding wire I was looking at is rated for 90 amps and these cables are rated for 400 amps... I'm serious, it says right on the package 400 amps for these 8 gauge cables... Is that O.K? I'm pretty new to this electrical voodoo, so if anyone could say ya or ney it would be greatly appreciated.

why was i told that the 4 gauge wire that i am using for my sub is not only overkill but bad for it due to too much resistance? I have not heard of this theory before, is there something that would support this train of thought? thanks chop

Guys, I watched a video of ***** ***** talking about **** amps , and they look awesome . Also they boast some big numbers. 1000 watt amp that pushes out 1600 and 2500 that puts out well over 3000. Has anyone used them ,or can vouch for these numbers? Any info will be appreciated.

4 years ago or so I got a SWEET deal on 6 Optima Red Tops. I can't find the guy and I don't remember what company he's from. Ring any bells for anyone? Anyway most people don't run Optima, why not? I'm assuming because more hours of sotrage can be had for less? I like the idea of dry/gel cells so that I can mount them any way I want inside the vehicle and no hydrogen gas released from charging. Anyone know if this guy is still around? What other options should I consider? Thanks! Krypto

When using 2 batteries, what wiring setup is the best way to get the most out of both batteries? Thanks in advance.

Hey guys, just wondering how difficult it is to disable the illumination of the logo on these amps. I don't have one, otherwise It'd be open by now. Also, is it only the logo that lights up? I know the 08 series there's LED's as well around the border of the faceplate.

The car is a Mercedes CLK55 2001, I have 2 amps 1 is 300 watts(150x2@4ohm), one is 1300 watts (1x1300@1ohm). For a total of 1600 watts. I have a Kinetik Power HC1800 as a second battery witch is to NOT let the lights dim if the system is under 1800 watts, unfortunately it does dim in the cabin and the amp for my front speakers sorta cuts out at loud volumes. once when i went from drive to reverse it didn't engauge and i had to put it in drive lower my system and put it in reverse, this has only happened once and i was beating really hard (i have not tried this again nor do i want to). I had a lexus 2002 ES300 before this and i did not have this problem, same setup. The 2n…

First question, Im thinking about making my own D-Block out of some bolts and nuts and what not, I have a run of 4 gauge from the battery, is it necessary to step down from 4 gauge to 8 gauge leaving the D-Block? The runs after the block are a foot at the most. Second question, what fusing should I use at the D-Block? I know 150 amp is recommended for 4 gauge but idk if theres a difference if its being distributed.

Here is the situation, I am looking into buying some 100wrms component speakers. I found this amp (Alpine MRH-F255) in my friends trunk and he said I could have it. After searching the internet i found out that it is running 35X4rms along with a subwoofer channel. Does anyone know how I would go about bridging this amp into a 2 channel (if its even possible). This amp is running a wire harness for its speaker outputs and so I have absolutely no idea on how I would bridge it... And if I cant bridge it, would 35 watts sound better than just the head unit to power the speakers (most likely Alpine spr-17s or sps-600c)? My second question is if i do deside to use the amp, I kn…

Anyone own any of these? Can I get 4 bandpassed outputs with it? I need 3 -way active... 2 outs for tweets HP, 2 outs for 4" BP, and 2 outs for 6.5" BP.... most crossovers only have 2 HP, 2BP, 2LP.... but I need FOUR bandpassed. Anyone selling any? Crutchfield says discontinued! http://www.crutchfield.com/S-A2KFWiqFKq0/p_500PXAH701/Alpine-PXA-H701.html]Alpine PXA-H701 Multichannel audio processor at Crutchfield.com Thanks!

has anyone used these? nothing pulls up in the search.

just got this idea sitting in econ today listening to my awful TA talk about derived demand for labor... I know normally the alt isn't used for transient loads, but would it be at all possible to hook up a power wire to the alt and send it straight to the amp, using a high capacity cap somewhere along the way to stiffen the voltage during amp draws? I was thinking that in this scenario, the cap would be acting just like a battery

ok so im running two CVX 12" @ 2ohm currently running them on a Kicker ZX 750.1 amp I know i am underpowering these subs. I am hopeing to get a 1,600 or a 2,000 watt hifonics amp Now my Question is are the hifonics amp's really good ? i hear good things about them and will a 1600 watt push the two VCX's really well or would it be best to have the 2,000 watt amp. Would i regret getting the 1600. i like my current kicker amp But it pretty simple amp and most def not strong enough

So I just picked up a 2005 TrailBlazer and the factory Head Unit has to go.... I have alway like Kenwood head Units so, I'm looking at the Kenwood DDX514.... http://www.crutchfield.com/p_113DDX514/Kenwood-DDX514.html?tp=20217 It seems to cover most of my wants... Nice Bright easy to see/read display in all lighting conditions. If its going to have one, it might as well be good! Ipod control, not just Aux input, but seemingly native controls with Album art, playlists and all (need a 30.00 cable) Ability to hook up an HD tunner (extra 80 bucks I think) Ability to hook up a Sirius (again Controls it natively, not just a aux input) (I have sirus and love it for travel) Abil…

My amp is mounted in the middle of my trunk and today i had to take everything out to install some more spl tiles i got in the mail, when i put everything back in and opened my trunk, a drop or 2 of water (it has been raining the past 3 days in st louis) fell onto the circuit board of my t2k...it fell in right by the phase switch. After that when i turned the car on, the sub (FI BTL) was making a awful low scratching noise, at first i figured it was the rca's to close to a power wire, messed around with the rca's which helped a little. I finally figured out it had to have been the water when i unplugged the RCA's and it continued making the noise until i unplugged the s…

i got a pos pioneer gm-5300t 2ch amp for my gfs car as a temp. amp while my mtx 7801 she was using is being repaired, when i got the pioneer one of the speaker output terminals was messed up and it keeps blowing fuses after playing it for a while, so i opened it up and removed the speaker terminals and soldiered 16ga wire to the board (the way all amps should be imo) and i bypassed the fuseing by soldiering a piece of 12ga wire across all the soldier points on the board for the fuses and i am going to run an 80amp external fuse, anyways i noticed a switch on the board that said bfc on the bottom and spl on the top and it was switched to bfc im curious to what this is and …

Good evening people I need some info on the epicenters , like the ones from Audiocontrol . What exactly do they do ? Is it a great plus having one if it's free. thanks

Im considering on buying one of these head units and would like to know if you guys have any opinion on which one you think is better. In terms of sound quality, functionality, features, ipod use

Is it possible to wire four 4 ohm dvc subs to a 2 channel amp, with each channel seeing 2 ohms? I have them running at four ohms, but can you use series and parallel wiring to create this load? If I set each sub in parallel wiring (+ to + and - to -, right?)and then run the - from one channel to one sub, the positive from that channel to the other sub, and a wire connecting the other + and - terminals from sub to sub, would this do it? Here's what I'm talking about. (pic may not work) Just hooked up these subs, but they sound distorted and just terrible, will they sound better after they break in, or just lower/louder? Replaced 4 RF P1 12's with 4 infinity 1252w's, a…

i have a m1d1 usamps amp. it says its a mono amp so does that mean i can only run one sub off of it cause the way it looks it has a pace for two. and if i can run two will they be getting the same power if wired up the same. say if i wire it to one ohm will they both be getting 1200 watts?

Does anyone have any info on the new Kole Audio TRAX1-7000D pics , tested RMs rating anything would help

I am looking to get yet another alt for my car and I know iraggi makes good ones but has anyone used one made by excessiveamperage? I dont want to get ripped off like I have read few have.
