hey guys i have an ef premium sound system that runs the origianl headunit double din, standard front speakers that i think are on the way out, different back speakers, and x2 4 channels amps and x2 12 inch subs.

The speakers have been cutting in and out over the weeks but now the stereo doesn't work at all. Ive checked all the connections and they are fine as are the fuses, the amps power lights still light up.

I have not checked the back of the stereo do u think that there may be a loose wire at the back of the head unit or if the front speaker is blown will it knock the rest of the speakers out of play.

Sorry guys for a long thread but how hard is it to take the head unit out???
