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.

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
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.

Do you have your power cables and speaker cables running on opposite sides of the car?
After that you should check your grounding.

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.
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.
RCA's to use
