Ok so the whole story is my deck stopped while a few years ago and I replaced it with an Alpine deck (they wired it in for me) and now (a year or two later) my rear speakers, the ones right above the trunk, don't work. This is a bose factory system and the only thing I've done was install an alpine amp and sub (custom install wired the power to the battery, RCA and remote starter to the back of the deck. Anyone have any suggestions? Much appreciated.

 

if they used the stock amp for your rear speakers the stock amp could have given up.
