Yeah I agree that its probably in protectionmode...fried amp=no lights, flashing light=its trying to tell you something is wrong. Sometimes (if you still have manual, or can find one to download) there is a rythem to the flashing and you find out whats wrong by what the code tells you. Worked for me on a kenwood deck I installed where a screw went through a speaker wire when the panels were put back into place.

I'd be checking connections if nothing else works...perhaps a frayed power or ground (even speaker wire) a loose wire in the strand crossing into another connection causing the issue. Many possibilities...hopefully you can find a manual and it tells you what the flashing means.

 

i checked the fuses and they were fine, the battery has a good charge. im almost 100% shure thats the only light on the amp but ill check again this afternoon when i get back to my car. im also gunna doublecheck all the grounds and wires. any recommended sites to find a manual for the amp?

 

either the manufacturer site, or try google...I've always bought my stuff new, so up to this point I've had the manual in hand

 

If you call or send an email to alpine (but i highly suggest calling) they can email you the guide
