i have a 2010 scab xlt.

i left the factory hu and the factory rear door speakers. i removed and replaced the front doors with infinity 6832cf's. i installed behind the rear seat a jbl gto504 amp. i also puchased a sub box and installed a pioneer 10" ts-sw251.

let me tell you, it sounds great. i will eventually change the rear door speakers to the infinity's. they made a huge difference by just removing the factory junk and installing these. much, much cleaner sound. i wasn't looking for something to rattle the windows, just something clean and crisp. i feel like i have accomplished that.

just thought i would share in case someone was curious as to what works. i got a friend of a friend to install the whole thing for $150.
