hmm, depends what gen you have, but I can tell you what ive done thus far (I'll have pics in a week or so, I'm in the process of transferring my system to the accord from my acura legend). I have eclipse 6.5"s in the front and I;ve made custom plates to fit Infinity kappa 6x9 3ways in the back of my 5th gen (stock speakers are 6.5"s). These things in and of themselves are not unique (although I am rather proud of my new speaker plates, I made them from masonite, DIY coming soon). These speakers are amplified by a 60x4 amp. The most unique part of my system is my sub box. I have two kenwood 12"s amplified by a kenwood amp 150x2. The box is isobaric. The box is very small with one 12" port with one sub facing out and the other sub mounted facing in directly on top of the first sub. The top subwoofer is run out of phase from the other. Hence, one sub pushes, and one sub pulls. This saves a lot of space and the bass is really tight but the box still gives a nice low rumble. There are people who say you lose output with this type of box but I noticed almost no difference between this box and my old two port. In fact, i think the bass is tighter now with the smaller box. Anyways, I'll post some pics soon. Good luck with your system.
