Hey guys, I've been off the forums for a while but I recently bought an 03 Protege ES with 55k miles for 5,500 in pretty good shape. I'm looking to (reusing the factory speakers), replace the cd player, add a 10" sub and box, and a simple amp to just power the single sub. I'm shooting for components pretty much just to get the job done, I don't need show quality or even looks really, and I plan on installing it myself. I should be able to get a receiver for about 100 because all I want out of it is decent sound and aux/ipod input. My main question is what amp and sub should I be looking at? I listen mostly to metal music, and it's not to blow the doors off, just add some bass to my factory system. Any info will be appreciated! I'm trying to spend around 400 or less bucks on everything.
