so recently i sold my old head unit and ordered a new one. For the mean time i obviosly put the stock radio in and now the stock sub and onstar arent working. After i took my aftermarket subs out, i had the stock sub in and was working perfectly with the aftermarket head unit. Is there something that needs a sort of "reset" or maybe a fuse? any help would be great. havent dug too deep in it yet so im just curious what any1 has to say...

thanx

 

huh. wait that doesnt really make sense. stock sub worked on the aftermarket unit. u did a swap to stock changed nothing and now onstar and stock sub only doesnt work? stock speakers play thou?

 

yup, stock speakers work fine... and there was absolutely no tampering with any stock wire harnesses' so now the sound system is like driving it off the lot basically..

 

but stock sub isnt playing?

 

correct, it isnt

 

unless you blew the sub or disconnected it it should still be playing. it uses the same channels on the amp as the rear speakers so there's no real possibility of the amp being bad since the rear speakers work. Onstar i have no clue. only thing i would guess is to make sure all the harnesses were plugged back in.

 

yeah, i'll prob double check that tomorrow. grab my multimeter and see if im even getting power there

 

subs a dual 2 btw
