Just put a box together after moving my rear seat forward some in my f250 crew cab. its 2.5 cubes total 1.25 each side sealed. after test fitting i could have made it bigger. I built this box for 2 IDQ12v3's which i was about to order. but after some thought and measuring i could build another box about 2.8 / 1.4 per side maybe a touch bigger which would be almost perfect for 2 IDQ15v2's. Im sure the 15's would get louder and lower but would the SQ be the same as the v3 12's? POwer is 500watts each and i listen to ROck,Jam,Jazz,live,Electronic/techno/house and some rap.
