MP3 unit for car

Hi everyone, I was wondering if I could get some help with a project I'd like to make.

My truck's stereo died, and instead of getting another stereo, I'd like to make a unit that just uses my MP3 player. Junkyard stereos are of dubious condition, and usually overpriced, and I'm too cheap to pay for a new stereo. I never really used the radio or CD player on the old unit; I just want basically a jack for a MP3 player/laptop, volume control, and power switch, powered by 12V and able to be hooked up to 4 speakers.

I have some basic electronic knowledge, but not enough to make something like this. Could someone maybe, possibly, provide me with a diagram or ideas to get this started?

Thanks a lot!

Is there still a tape player in the car? Sometimes the CD player and tape player are separate units, if it's still there, you can buy a tape to aux cable adapter.

If it isn't there, I really can't help you there. Good luck!

Nope, the old unit was just a CD/AM-FM/Aux thing.
