Hey, I am deployed, and just bought a Scion tC without seeing it. (Do not make a comment on that lol. Life is about taking chances) Can anyone tell me if I can put subs/amp up to the stock head-unit? Or would I have to replace it. I got the upgraded Pioneer stereo head-unit, and I believe it comes with one subwoofer. My dad says it almost blew him outa the car, but he doesn't know much about systems.

I would love to put some JL Audio W7's in there, but I am not sure if I can, or how big to go.

I appreciate all your help
