the ONLY reason i grounded it in seaparate spots is because one ground on my 4 channel amp would need to be extremely long to reach the ground for my cap and sub amp... i HAD it like this and STILL had motor noise... that is why i changed it... i made the grounds MUCH shorter and grounded all 3 directly on the frame (2 on one side and 1 on the other) it didnt change anything and i know i dont know a WHOLE lot, but if it was a bad thing the noise would have been worse this way.. also my signal cables run down the center of my truck not crossing any power wires.. the only place it comes CLOSE to a power wire is when it connects to the amp.. also where i had everything grounded to the same part on my frame, the metal actually changed colors a bit.. this is also another reason that led me to changing the grounds.. another question.. if it had anything to do with the grounds on my amps wouldnt the noise still occur with no signal cables connected to my amps (with my amps still on) because when i disconnect my signal cables it goes away COMPLETELY.. even when i disconnect them from my CD player it goes away COMPLETELY.. so I'm believing the noise is being picked up through my CD player some how other wise it would still be there when i disconnect the signal cables?
