I'm wondering what kind of RCA cables everyone else is using to get from the HU to the amps. I'm getting alternator whine in my system and believe that the RCA's are the source of the problem. So peeps without alternator whine, give me some recommendations. Thanks.

Your alternator whine might be from your grounds.

probably not but it's possible, usually when it is, it's common to the entire model, not just the one vehicle, case in point the hummer h2 is like that from what I have heard, but then again it is something to check

I run Stinger Expert series RCA's in my car, very nice, but VERY expensive.. you might be better off with something like the bullet series

Hum is usually bad ground or having the RCAs near the power wire....

I run whatever wire they give me. Right now it's Lightning wires. Were I going to buy some wires, I'd look into Knu wires. Lots of people that I have read reviews from have had nothing but praise for them.

I just got the JL Audio RCAs along with an entire JL Audio amp wiring kit..

Just go back and check your grounds first. If you want top notch RCA for a good price, Knukonceptz krystal series is only $20.

I'm probably just going to go with the Karma cable myself though.

Try check grounds, make sur eyou're not running them near anything else, and try lower your gains on your amp.

Do you have your power cables and speaker cables running on opposite sides of the car?

After that you should check your grounding.

what brand of amps are you using?

as others have said - check your grounds first. What gauge of wire and how (where) did you ground them? Proper installation encourages keeping RCA's as far apart as possible when running cabling.

I'd also test it before ripping your vehicle apart for replacing them....

I don't think it is the amps. Right now I'm running a Kenwood 4 channel and a Bazooka mono, but those are being switched out with Phoenix Gold amps within the next couple weeks. Also, I don't think its the power. First off, I have power running down the center of the car and RCA's down the passenger side. The only place they are close to each other are the trunck for maybe 2 feet and the 0 gauge power I have is very well shielded. I also don't believe it is my ground since I ground back to the battery.

Hey, I thought you were suppose to ground your amp as close to the amp as possible. That might be a problem, but I'm not sure. You used twice as much power wire than you should have man.

Also, you should have ran the power wire down the passenger and RCA on the driver or center. Why did you decide to cross the RCA and powerwire near the headunit? That might be the problem there. You are suppose to keep the RCAs as far away from the power cable as possible.

Wow! I just sat here thinking that you used 0 gauge wire from battery to amp, then amp to battery. Crap man. That is expensive wire that you abused...haha.

Try using factory grounds.

It has nothing to do with grounding within 18 inches of the amps. With my old setup I was grounded within 18 inches to the frame and still had the whine. Also, my power doesn't cross the RCA's at the HU. My power runs through grommets I installed on the drivers side of the firewall.

I've come to the conclusion that getting well shielded, balanced RCA's will probably fix this problem.

Try the placement of the rca's behind the HU, what kind of HU do you have?

Make the grounds as short as possible.

Where is the location that your amps are grounded to?

How good is the contact between the ground wire and the location it is grounded? Did you file off as much paint as possible? Can you scrape away anymore?
