I have been driving without a stereo now since I bought my 97 Blazer, and I can't figure out what's wrong...

I bought an aftermarket deck with a harness kit, doesn't work.

So I tried plugging in the factory deck... nothing still

The previous owner had some crazy wiring setup in it and I believe they may have bunged up the wires...

How can I properly diagnose this?

 

sounds like the speaker wires aren't connected. does your unit have power? did you match all the colors right? There could be many problems you have a to be a little more specific in "doesn't work"

 

There is no power to the unit.

I lined up all the colours and got nothing

 

have you checked the fuses?

 

if fuses are good, make your own ground. if that doesnt work run your own power wire. if that doesn't work take it to a pro.

 

It was the power fuse. Thanks all. Now my speakers dont work, gotta replace those
