Have Engine Noise In Your Skyline?

[nemz]

after months of purchasing new audio equipment, wires re wiring, going through hell to stop that annoying whine, which never occured when i had a small system set up, i narrowed it down to 1 thing, my rca cables, how to solve it

in my case, 2 things have worked

1st, my big fat cadence cables i ran 6x wires from an earth from the back of my boot, to each of my 6x rca head where it plugs into the amp i edited a pic of an rca which u can view if u dont get what i mean

or the second thing i also tried a very thin rca home av cable i got from dick smiths as one of my cadence cables the connection messed up because of there dodgy crap soldering job on the internals, yes dont buy these rca's even my other 2 sets loose connectivity some times and speakers cut out!!

but yeah back to the point with the thin wire which dosnt let through as much signal dosnt seem to let through engine noise and didnt need to earth it like the cadence so yeh hope this may help a few people

wtf?

So... you ran grounding wires from the boot, along with the RCA's, to the ends of them that plug into the HU, and then used the outer part of the RCA for the grounding?

I've tried this method also, with some success. I could cut the noise out of one set of RCA's, but not out of the other... no matter what I did.

In the end, the HU and amp should both be grounding the RCA cable, and if it's not, you might have blown the grounding circuit in either of the above.

I opened my Kenwood HU a while back and found a burnt track on the circuitboard which led to the ground of the rear RCA outputs. I soldered in a piece of wire over the gap, but it didn't change a darn thing. I guess the HU is just stuffed. (changed amp and RCA's) Oh, and I tested my new wire with a multimeter, and it's fine. There's probably another cut somewhere else that I can't find. (no fuses for ground)

no i just ran the wire from my boot catch, the 2x bolts which hold the boot latch in strait to the female part of the rca in the amp, then plugged the rca's in

sweet.I had a good ol gemi n had a bompn systm in that.The rca cables i bought for it were jaycar items n they came with an earth wire allready attatched end 2 end.So obviously they had stumbled accross this problem b4 n rectified it.
