So I bought a 1997 Chevy 1500 W/T and it had an aftermarket Pioneer DEH p580mp deck in it and it was all messed up...two speakers had lose wires, antenna wasn't plugged in..etc. I took it all apart, rewired all the connections with new tape, and wired in 2 Memphis Audio door speakers. It sounded great, except one of the MA speakers wasn't working like it should...it was only getting high end from the tweeter, so I swapped it for a pioneer and while I was wiring up the pioneer all of my sound cut out. I, once again, ripped it all apart and rewired all the connections and I still get no sound. Fuses are all good including the 10a fuse in the deck behind the harness. I can see that it is on, playing a cd and tried the tuner...but still no sound...not even a small hissing or anything. It's like my speakers aren't getting any juice from the head unit at all.
