I would have yanked this head unit 25 years ago, but not now. Just seems right to keep it. Im sure im not the first, but this is what I used. Audio Control sound processor to convert the stock signal to something an amp can use. 5 channel JBL with Bluetooth, dooky pre-built sub box and a Menphis Audio 10" sub. Memphis Audio stock size speakers in the doors and deck. I think it sounds great for the $600.00 I have in it. Especially considering the 4x10s in the back. Radio reception sucks, so I need a suggested fix for that.
