Thanks everyone. My goal right now is to get back into car audio and setup a new system. I currently have a Pioneer deck, factory Alpine system in doors, a Crossfire XP1400D amp and a 12" Orion H2. I'm debating on changing to some slim/shallow subs. I've been out of the game for a minute and I have no idea who makes some good shallows that I can run with the 1400D. I actually have a spare XP1400D collecting dust. Maybe I'll consider trading or something.
