noise noise noise
im going to f'ing kill myself if this noise don't go away.
i am attaching a rough drawing of my power system. i need help to resolve noise in system. it is not engine rev, more of a whistle type humming.
what i have tried:
i have used inline GLI's on HU, xover in, xover out, xover in/out, one amp at
a time and then all amps - limits my tweets!
i have eliminated amps one by one by removing from system
tried to use extra ground on each amp and even on HU casing
i have bought new rca's (6 gold plated $30 sets - kicking myself now)
i made sheilded rca's
i made unshieleded rca's
my power is run outside of cab underneath in pvc flex, my audio is run in pvc flex sepreated from truck wiring along doors.
i never had good luck using chassis grounding so i started using all d-blocks and until now never had issues.
only hear noise if turned down low or muted.
i had same setup in 1998 dodge quad and it was QUIET.
muted radio = is it off???
anyone have suggestions that will help or completely remove noise???
also, need some prayers for my windshield, the bass was hittin' hard today

noise noise noise
power run - outside passenger
audio run - inside driver
noise from whole system: 4 tweets, 4 doors, 2 - 6x9's and 4 subs
i did change speaker wire also. on subs went from 12AWG to 10AWG
amp 12+ longest is 15"
amp 12- longest is 9"
6x9 = 12AWG 3 ft
subs = 10AWG 2ft

I asked about the hu because if it was a pioneer might be the pico fuse problem, but you have a kenwood.
By the way some times you get induced noise on the relay that is used for the rem distribution, disconnect the relay and try the rem directly to amp one or two at a time.

i have a digital voltmeter with +5/+12 input. i built a small 5v regulator to get display working. i guess i need to filter the regulator now. i do thank you very much for all the help and thoughts.
