This is a stupid question...but here it goes!!!

I was wondering if anyone knew if you could hook an amp and a sub up to the stock JBL deck? I don't believe you can, but I thought it never hurt to ask!

You can't add on directly to the deck because it doesn't have any pre-amps, but you can purchase this box, I forget what its called, but anyway it attaches to your speakers and it has rca pre-amps on it, so it gets the signal from your speakers and you can go from there. I know its possible cause I had one in my 89 mustang with the factory radio, electronic cross-over, amp and 2 10s. But ask you local audio shop they should be able to help you. I hope that this helps you out! thumbs_u
