Hello all,

I have a 16 base gt with the 4" screen. So, I went out and bought the 8" aftermarket screen. I had it hooked up and running fine. I decided to add an amp; so I put a LOC behind the dash, connected to the speaker wire. Upon putting it back together, the screen won't turn on. The speakers are working I think, but no music, screen.

I'm still a beginner, but I tried some troubleshooting. I checked all the harnesses and wire - nothing obviously damaged. I checked fuse 32, 33 inside, and they are good. A fuse was blown under the hook, Auxiliary power point, but changing that did nothing.

What else can I do to troubleshoot?

Thanks.
