Ok, I want more bass in my car, I only have two 6x9's (boxed), and at the moment the bass is there, but its quite boxy. I dont want to put a sub and and amp in (cant be fucked with an amp, and dont really have the room - its an MR2).
Are there 6x9's out there that will give me decent bass (I know it wont be as rich as a sub ever)? or what about those sub/bass tube things. Are they any good? can I just hook em up to speaker wires, or do I need a line level output? Is there anything else like this?
