Car Stereos: Bazooka Amp Issue, amp input, pioneer stereo

Question
I bought a 4 channel Bazooka amp and set up a whole 4 channel system by myself. I wired the speaker out put wires from my pioneer stereo to the amp input and ran my own wires from my speakers to the amp. I plugged everything in and encountered a problem. The rear speakers work just fine when I plug the speaker signal wire from the stereo into the amp . However, when I plug the front in it creates major rythmatic beats in my speakers and the lights on the Bazooka amp flash green and red. Why is my amp doing this and how can I fix it?

Answer
It sounds like a short somewhere.  Try the front signal wires in the rear connection of the amp.  Then, try the rear signal wires in the front part of the amp.  If the funky sounds come out of the rear speakers (while the front signal wires are connected), then you know the problem is between the stereo and the amp.  If the front speakers spaz out with the rear signal wire connected to them, then you know the problem is either the amp or the wires from the amp to the speakers.  I would check the wires first.  If the wires all seem to be ok, then the problem is probably in the amp somehow, and it should be tested by a professional.  Hope this helps, Scott
