Cheap speaker setup
I drive a delivery truck all day with out a radio, I was going nuts without music. I don't wear earphones while I drive so I jury rigged a system using an old Sansa M240, a pair of Sony SRS-P7 passive speakers, a Kensington USB car charger and a USB to Mini USB cable. I used AnyAudio converter to copy about 800 mp3's at 92 bitrate so I could fit them on the 1 gig memory of the M240, it's about FM radio quailty. The sound is surprisingly loud considering they are passive speakers, I don't realize how loud until I get out of the truck to deliver a package. I use the usb charger to power the Sansa so I don't need batteries.
