wiring help (amp wont power on)

[Vinsanity86]

Hey people, old member but new post since 08

So I have Valor 660 headunit with a Nav-2 installed it myself

professionally done---->

I have 4 gauge wiring connecting my facotry toyota battery to my TMA amp

( http://www.totalmobileaudio.com/products_amps.php?amp_id=435 ) which powers my two 10" W3's nice little system nothing to get crazy with.

There IS a Rockford fosgate 1ohm capacitor hooked up ( i dont know much about capacitors but i think those bastards gyped me........I also loosened and re-tightened the ground wire to the amp so I dont know if messing with that would have affected anything, or maybe not tightening it enough is an issue)

But the issue is ever since my accident and getting my car out of the shop the subs wont hit. I checked the amp and the green light is VERY FAINT..often fades out...then goes into protection (red FAINT light). The amp works (i think) because the subs will hit once or twice on a beat then go faint/dead.

Can ANYONE help me out!!!!

THANKS

Definitely check the ground... scrape the paint away and use a nut and bolt to secure it to the body of the vehicle.

did they disconnect the battery when they fixed your car. sounds like a ground is loose somewhere, whether it be your amp ground or even your battery ground possibly. check out all your grounds and see if that fixes it.

Thanks a MILLION, system is back and running. Reconnected the capacitor, and SUPER tightened the ground and seems to work fine now. I DID have a question I feel like my system is draining power and functionality to the car stock wiring/electrical. Does anyone have that issue or know what the problem is
