grounding problem or rca's?

[muddybass 13]

i have a wierd problem i just installed o ga wire under the hood for the big 3 and now i have a really bad ground problem like i hear when i hit the brake pedal even the turning signal and cant understand it. i grounded it to the frame and vehicles factory location also sanded them to bare metal... and just the other day now if i turn it up to a certain volume it sounds like the woofer flop or play out of tune thats why i was thinking it might be the rca's any help appreciated.... i run 2 12'' q's on a everest soundlabs prototype amp box is 5 cuft and tuned to 30hz

How do you have your signal wires ran? Alongside or on the opposite side of the vehicle as the power run?

a lot of people develope engine noise when unplugging rca's when power is to the headunit blowing the pico fuse. Did you follow existing grounds for the big three or create new grounding points.

 did you hot swap the RCA wires,. ( unplug them and plug them back in while the radio was playing?

 

 also did you ground your body to the frame aswell..

 

 and lastly how is your amp mouted?

 did you screw it into tthe metal ?

the signal wires are ran on the opposite side of the power wires.... i followed existing ground on the big 3 but took the old ones off and sanded down... ill post a pic later how it was grounded but it all started when messing with the alternator.... and the amp is mounted to a carpeted board underneath the box, as far as hot swapping i may have done that in the past

did some testing and figured out the rca's went bad and were pulling ground noise.... thanks for the help
