Ok this is an odd one!!

I've tried to install a amp and sub into the rex but man is it complicated!

I've bought a Line Out Convertor so I can use the RCA's and Hvae hooked this up to the 6x9's Took the remote from the green/yellow (i think) wire from the bose amp, grounded the amp and run the power cable all to the amp.

The problem I'm having is that I had tried a amp which I didn't know if it worked our not and the amp light was coming on but there was no output from the sub. I had then started the car and the sub had started to "vibrate" but didn't play the song!!

I had then tried my brother's amp in the car which i know works and now that amp is not powering on!!!!

Any Suggestions!?
