wiring question

[SUPERMN]

ok so when i got my 92 it recently had the head unit replaced with a eclipse unit, im guessing they bypassed the factory amps, well after about a week or 2 of playing the rear speakers are starting to go, there stockers,loL! which actually were sounding pretty good, im happy with the volume of the eclipse head unit but im also wandering is there a way to reconnect the factory sub/amp up to the eclipse head unit?? im just going to replace all the speakers , but i would like to use the factory amp, whats a good replacement sub for the factory amp and all, assuming i can reconnect the factory amp to the aftermarket head unit

I think this would help you with using the factory amp, just wire the speaker wires to the small square harness and plug it into the wire that goes back to your factory jbl amp, assuming you do have the JBL Audio Package of course.

As far as the sub, i have no idea i havent looked into it, i bypassed all factory stuff and am putting in my own...
