any recommendations for an 03 honda accord

I think i could really just use a sub and amp but any ideas you guys have would be great.

Its all stock right now its the head unit with the dual zone climate control so thathead unit must stay but i would be willing to put a head unit in the lower cubby.

I want to keep costs low and it doesnt have to be a crazy system just something nuce with some bass. Max price would be 500, less if if it is just an amp and sub.

any guides for install would be great too since this will be my first system
Thanks!

craigslist some jl subs

anything else? i have seen some mtx audio packages, how is the mtx stuff?

I suggest you do a little search first, then ask questions...
