Sheesh, don't you dare take your truck to an audio shop to install new speakers. Its just a couple of screws and 2 10mm bolts. It's not too hard to chop something up in the back and install 6x9s or something. I cut holes in my little side cargo compartment covers and mounted a couple 6.5" speaks back there plus a small powered 8" sub. Its not gunna break any glass, but it makes a world of difference. If you really care about your music, the 2 stock 4"ers will never cut it by themselves. Having said that, Kicker makes a nice pair that you can get for pretty cheap. Like 40 bucks maybe??

 

getting 2 4 inch fusions just to replace the stock ones wasnt going to take it there not that i ripped it apart
