A friend of mine installed a set of 6X8 speakers into the rear deck of my 98 GT and wired the high pass amp to the tweeter and the mid range amp to the woofer. Everything was cool but after an hour it smelled like plastic was burning and all my speakers started distorting and then finally cut out. I have checked all the fuses, and everything is fine. The radio seems to work but no amps kick on and there is no volume. Are my amps blown front, 2 rear, or is it my head unit??? Any help would be appreciated because no stereo is killing me!!! Thanks.
