I have a 2000 mustang and i installed a jensen vm9312 aftermarket radio.know when I play a c.d. the radio plays on the back speakers while the cd plays on the front speakers. Also when I switch from off to on there is a thump. I did not have the mach audio system. please help.

a couple of your wires may be mixed up on your wireing harness and just because you dont have the mach system dosnt mean you dont have a factory amp when you bought you aftermarket harness did it say it was for the premium sound system ??? i have a 96 V6 that has a factory amp
