Install Help

[skippadude]

hey all,

was hoping someone might be able to help me with an install im currently doing.

ive got a 4ch amp for front 6 inch splits and rear 6x9's and a mono amp for a 12inch sub.

ive wired it all up except for the front speakers running the rca's from head unit to amp and then speaker wire from amp to speaker and am getting some massive feedback from the rear speakers, the wire's are running the same way as the amp wires and there is no issues with that. i also pulled out the rca's so there was no chace of interfearance from the power but same issue, all feedback no music.

any help or pointers would be great

thanks all:)

Check your grounding mate,

Run RCA/Speaker wires on 1 side of the car, Power for the Amp on the OTHER side of the car.

Check that you have clean grounding, check that ground from the battery terminal to the Chassis/Body (R32 GTR has a shocking battery earth).

Make sure your grounding is less than 1 meter long from the amp to grounding point, the shorter the run, the less resistance on the cable.

thanks for the help guys,

sounds like the grounding is the way to go, i'll also re wire so im away from the power cable. while were on the topic can anyone suggest a good grounding point in the boot of the r32, i just took off a couple of bolts i found attached to the chasis, cleaned off the paint and replaced. also can i use the same grounding point for both amps?

cheers

+ 1 for what the others said, but also check your head unit. I had a really annoying interference problem with a similarly setup system and I tried everything from noise filters, re-earthing, new RCA leads etc. Ended up replacing the head unit and the problem disappeared!
