I have a couple things in my Ranger
A Kenwood Amp 4-channel amp powers the subwoofer and the two door speakers
I don't need a CD player, so I decided to get an Alpine iDA-X303
Under the dash is the Polk Audio 6-1/2-inch center channel speaker.
The amp that powers the center channel is in a custom made kick panel
There are two five inch monitors. One mounted on the overhead console (currently displaying engine diagnostics) and one mounted in the passenger visor.
The DVD player is in the ashtray
The ipod is mounted in the overhead console. Also the mic is for the Bluetooth Phone
There is a third amp that powers the tweeters, I'll get a picture of it posted later.
