i have pioneer 4" in the front, cant really go any bigger than that, in the rear i have some infinity 6.5" speakers. then a 10" JL sub out back. it sounds awsome, my deck has built in high pass and low pass filters. so it runs crystal clear at any volume. running a high pass filter through your mids will save them from self destructing, and do more of what they were ment to do. and the sub will take care of the bottom end. my box in the back fits nicely behind one of my rear seats. and i still have room for the other one to flip up, so i still can get grocerys and stuff.
no only if i could get my engine to run...........
