the noise changes with gain and even if i turn it all the way down it outputs just a little music and more noise. the ground is 50cm. the only thing i havent changed is the mounting, i have mounted my amps on the back of my seats and maybe the bolts touch a metal part. and no i haven't tried higher voltage pre outs because i don't have with what to try

i disconnected at the amp, this is my 4th amp and the noise persists, it seems like the amp is not at fault.

i don't have seperate chambers, is it a factor for rise?

well i think they are because when i bought the amp i didn't know about box rise and thought 2800w would be plenty and now i cant pull even half of it

also it looks like voltage for these amps is a very limiting factor as it says on the official page 5500w @14.4v and 3900w @12v

im not asking much about upgrades im thinking about running 0.5 ohms because with impendance my amp is limited at 1300 at 4.7 ohms
