I put two 5.25 beside the driver in the side panel, then a sub up front with a amp and let your iPhone be your stereo just plug it up to the amp and download audio xciter as your player you can adjust your sound with it. If you don't want to cut just get some 6x9 and put them in a box. I would also recommend if you download any songs from a computer to your phone to make sure they are set at 100% most of the time they are set at 50. You can YouTube that and see how it is done.
