Got a problem, need some help

[dragnix 5,000+ posts]

Ok, let's start off with my setup. I'm running two amps right now, one for mids, one for highs. Then I added a third amp for the sub. The problem is the sub amp turns on, but there's no output to the sub. The only thing it does is that the lights dim to every bass notes. The sub is a d2 wired to 1ohm. Not entirely sure as to what the problem is or if I crossed the wiring somewhere. Any ideas?

as far as i can tell everything is hooked up correctly. RCAs are ran along the same side as the RCAs for the two other amps.

check voltage at all amps and also check the grounds too.sounds like a bad ground to me.you may need to add a relay on the remote wire too

Ground is 1/0 from batt to distribution block to amp, but i'll recheck it when i have free time. Already have a relay for the remote wire. Any other ideas?

what happened to my old amp?

if grounds are good they next would be voltage ,process of elimination

Sounds like a short in the sub or sub wiring. Drawing current from the battery but no output...

Coils out of phase on sub?

could be possibilities, it was pretty dark when i wired the subs
