SubThump Wiring Harness HELP !!!!
 

I put in the wiring harness which gives me the pre-outs for my amp and sub. I hooked the cables to the Rear Right and Rear Left. When I turned on the radio, I got a crazy squeal from the rear speakers. I tried the front pre-outs and the same thing happened only coming out the front speakers. The first time I had everything connected, Power, Ground, Remote, and Signals and the amp smoked a little. After that I disconnected power to the amp. No smoke but still got the squeal from my speakers. If I discounted the RCAs, Everything in the car worked perfectly with the harness still in.

Any help would be much appreciated. And this is not my first install, in fact the amp has been in 5 of my previous cars.
