Ok I am still new to the gto scene and I have a few questions about the stock audio system. I already added the aux in mod thanks to help from people here! So my question now is the stock subs/amp. I knew nothing was coming from the rear deck speakers, I assume those are the subs. I traced down the stock sub amp in the trunk and the fuse is blown. It has a 10a in it, which seems small to me... Does anyone know what size is supposed to be in it? If I get it working, I also plan on replacing the stock subs with 8" kicker comp vr subs, I have read on here about ppl doing that with more success than just putting a sub in the trunk. Next question, when I replace the stock head unit, will the rear sub amp/subs work with a aftermarket headunit?
