I need advice on what to stick into my 03 GT. I'm not trying to kill my bank account (save that for the performance parts...) but I'd like something that'll hit nice and loud. I just put in a Kenwood KDC-X493 Reciever, pretty cheap piece but noticeably clearer than stock. I'm not sure where to go next. I suppose the logical step is a sub/amp box..

Anyhow, if anyone has any ideas on where to go for a solid setup, I'd really appreciate it. I want it to fit in nice and clean...trunkspace isn't too important as long as I can still fit a military kit bag or standard size suitcase.
