Hi there, im new to the forum and to the electronics world, (i've read the FAQ's though, but still...)and i wanted to ask your help, this is the deal, my car radio was stolen, and i thought about doing something myself, like just pluggin an MP3 player to the amp, wich is wired to the car speakers, since i dont know much about electronics, i wanted to know wich one is the best from this list:
Index of /Audio/Circuits
i've seen the power amplifiers, cause i thought inbetween those is the one i need, also, if you have a better one, please tell me

Thanks all you guys,hope you help... :)

P.S.:whats the differencee between the class D power amplifiers and the linear power amplifiers?(btw, those are in the list)

I'm going to just bump this, cause I know there are lots of audio guys here who probably have a diagram ready to go.

The powerful amplifiers in that list need a supply voltage that is much higher than the 12V in a car. High power car amplifiers use a complicated voltage stepup circuit.
The "16W" car amplifier produces only about 14W per channel and uses obsolete amplifier ICs.

A class-D amplifier is too complicated for a NOOB to make.

An ordinary car radio has 14W per channel at clipping into 4 ohm speakers.
A TDA2005 or TDA7240A amplifier IC can do it per channel and the schematic and pcb design is in their datasheets.
