Hi, would it be possible to remove my crap radio from my new-old car, and in its place, put some sort of homemade amp, and a stereo jack that i could plug my mp3 player into?
If it is what would i need.
I have some low voltage audio op amps(4 * LM368), would these work?

If your car was a Rolls Royce, where the loudest noise inside is the tick of the clock, you may be OK with those - but otherwise they are FAR too small for in-car use. Be easier to mod your existing radio to plug your MP3 player in, or if it's got a tape on it?, use a tape adaptor to connect from your MP3 player.
An LM386 creates only 0.5W into an 8 ohm speaker which is not very loud.
Philips and ST Micro make hundreds of car radio amplifier ICs that create 15W per channel for two stereo channels. Make one from a single TDA1554, two TDA2005 or two TDA7240 ICs.
It depends on the exact radio you've got, electronically it's VERY simple to do, basically just connecting to the top of the volume control - but if it's done electronically it's a question of finding where it is!.
A circuit diagram or service manual would be a good help!.
I guess they are becoming obsolete. Worldwide Farnell doesn't have any. Digikey in the US have some that are made by an IC maker that I never heard of.
When so many consumer electronics things are made in The Orient and are using Oriental copies of standard western ICs then the western ICs become obsolete.
Farnell in the UK have many TDA7240 mono power amplifier ICs in stock.
Hi,
You want a circuit diagram. . . For your car? or for the stereo?
If you want wiring diagrams for your car, then try to get hold of a Haynes Workshop Manual for your model. They have complete electrical system information in them. You may be able to get this info on the net, but it may not be free.
If it's for the stereo, then your best bet is to search the net.
