Will New RCA's Remove Alternator Noise?

Sup guys,

I have alternator noise that’s driving me insane, I have tried several times playing with the cables, readjusting the wires, re-positioning the ground, I’ve even purchased one of those noise Filters and tried installing it to the radio and then to the amp and nothing. I made sure to run the rca’s opposite from the power cable and turn on wire when I initially installed the amp. The Ground wire is securely grounded to the chassis underneath the rear seat. I made sure to scrape the paint before screwing the ground to the chassis. My question is this, being that I purchased a amp wiring kit, which brings the rca’s, ground, and power wires I thought perhalps the wires might have been cheap and contemplated purchasing a set of good rca’s something like knuKonceptz. Would someone recommend doing this? Do you think this will remove the alternator noise? Someone mentioned purchasing a cap but I’ve heard it wouldn’t help. Also where do you guys have your ground wired screwed down too?


Current System Setup on 99 Spyder GS:
Pioneer DEH-P8600MP (Head Unit)
Pioneer 200W 3way (Front doors)
Pioneer 220W 4way (Rear)
Kicker Solo-Baric L7 10" Subwoofer (Ported Box)
Alphasonik Amp PMZ12005A (5Channel 1200W )

I believe the specs on the alphasonik read,
120watts x 4 @ 2oms + 320watts x 1 @ 2oms

On my spyder the ground is bolted to the cross bar in under the top. Their are severeal bolts on it just the right size. Sand and land your wire on it. It's most excellent.

I run the power up the passenger side track in the floor. The RCA's and remote turn on go back through my center console and in under my back seats. I didn't feel like running them back through a side track.

No noise what so ever. The system is as my sig says.

First of all, you have been here long enough to know to use the sub-forums. Start using them because you damn well know this would fit under Problem Diagnosis...

There is nothing wrong with the RCA cables you have. Here would be the cheaper solution to try first. Wrap the cables in aluminum foil... I'm not even kidding either. It will shield the cables from any noise interference you may be getting from any electronics in the car. They make special covers for this but they are a ridiculous amount of money and the aluminum foil is the same thing for much cheaper. Give that a shot then if they still receive noise you have a bigger problem than just interference. I had no noise problems when I put my system in and I didn't even have to shield my cables... Also, make sure to run the power cable for your amp down one side of the car and the RCA cables down the opposite side. This could cause horrible noise interference if you ran them both on the same side.

I was having the same issue that your having, I tried every way possible to fix the issue including buying 2 of those noise filters and putting one at the amp and one at the deck but did not fix the issue. It turned out to be something wrong with the amp, I got a new one and the problem went away.

btw, I made sure to run the rca's on the opposite side as the power wire. However, is it ok to have the turn on lead and some speaker wires run on the same side as the (red) power wire?

Move the speaker wires... Thats a big problem there... Or wrap them in aluminum foil also and it should shield them enough to eliminate the nosie your getting...

I've heard that you can also use electrical tape to cover the wires but that might take some time to wrap the entire wire with the tape but hey whatever you wanna do.
