Hi guys, here's my situation, please help me out if u can. This is kind of long, so please bear with me. Thank you.

I was in the process of upgrading my cd receiver in my 1993 Toyota Supra. I replaced the factory deck with an Aiwa deck, MP3
capable. While wiring the harnesses together, I found out the front right channel doesn't work coming from the deck via the
harness. So I bought a Rockford Fosgate amp, 400a4, to solve that problem by using RCA cables. Right now, all wires are
hooked up for testing, so I haven't start running it yet.

Here's how the wires are hooked up. From the deck, RCA cables are going to the amp, and to my Bazooka (RS10A, amplified). I
hooked up the front two channels to the amp, and the bazooka also to the amp. The rear two channels are running off the deck.

Now, after i turn on the power, and whining noise appears, even with the volume turned all the way down. It sounds like a
whine/whistle, or a turbo spool. When I step on the gas, the noise gets louder. The thing is though, only the front two channels
(which are hooked up to the amp) have this whine, the rears doesn't.

I called Rockford, and they told me to check my ground, which seems to be okay. I am using an 8-gauge wire for both power and
ground. The amp is grounded to the bolts that hold down the rear shocks. They've also told me to run the RCA wires on the
opposite side of the power wire. I've seperated the two wires as far as I can, but the noise still exists.

I'm completely confused on what the problem is coming from. At first I thought the problem was a bad amp, but when I hooked it
up to my friend's system, there are no whinning noises. Could it be a bad deck? What else can cause the "whine"? Please help!
Any input is greatly appreciated. Thanks again!!!
