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)

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.

    • Sorry, are coilovers ACTUALLY ILLEGAL in NSW? They aren't in Vic, as long as they retain 70% of stock travel and the car is above 100mm off the ground. Does NSW actually have a law making coilovers actually illegal? RWC/Blue Slip/Engineering people not knowing the actual f**king laws boils my blood. Demand them to point to the documentation that states a coilover is illegal. (it may exist in NSW )
    • But seriously, can we ask for the results of the "tip a bottle of metho into a nearly empty tank" experiment?
    • Hang on. Let me get this straight. The desire is to have coilovers, BC in particular, to be MORE comfortable on Sydney roads than stock suspension? Well, that's obviously not right. BCs have crude damping design at the very best, and typically hard spring rates. BC stands for Billy Cart. And then, the desire is to put in some shitty old worn out stockers, to get it blue slipped and then put the BCs back in? And then.....what? Not worry about getting pulled up by the Plod? Because you seem to have raised a worry about paying for engineering (which actually does solve all your legality problems) and still getting pulled up.... but the only problem there is that if/when that happens you have to show your paperwork at the inspection station. Whereas, if you just swap in borrowed shitty old stockers to get it slipped now, and then you get defected in the future, you have to go find more shitty old stockers then too. You course of action looks like this set of options: Buy brand new stock type dampers, and springs. probably cost a bit more than $1k all up, but will last for the remaining life of the car. Put them in, pass inspection, drive on them forever more. Hell, they could even be really nice Bilsteins and Kings or other lower&stiffer springs if you wanted. Get the car engineered as is. ~$1k. Buy new Shockworks coilvers (or MCA) and also pay for engineering. You're spending a lot more here. But these will be the best things that you could drive around on.
    • Might be worthwhile hitting up Facebook's groups, I know most of them contain terrible people and scammers - however you might be able to find someone that's in Sydney with factory suspension you could purchase and/or hire. Just do not send any form of money anywhere, in person cash only.
