decided the stock stereo setup was a little underpowered so me and my buddies decided to put a sub and amp into my supercrew. i had a amp laying around but i needed a special box and a small sub. we started shopping around noon and after going to a few shops, stopping for lunch and then installing everything, it took us 5 hours. not to bad since we couldnt find a wiring diagram for the stock head unit so we had to do some testing with the multimeter. in total i spent $270 for the box, the sub and the install kit which included some hi/low thing.......i dont know what its called but i was told i needed it when hooking a sub to a factory radio. anyways, here are some pics.
as of now, there is only one 10" and it sounds great. when i make some extra cash i will get another 10" and a better amp but for now, i love it
