Hi can you show me any links for this?i want a 2x20watt rms type of thing...

i DID have a site online,that used toshiba IC amps,but i lost it!!! it was a search in google,but i cant find it anymore

Thanks!

Most car cd players do about 20wrms, friends one manual said 19wrms. I'd suggest pulling a dead one apart and seeing what chip they use. They use the cars power rail, no power supply stage, channels are just bridged.

Jaycar do a TDA something (the only one they've got) that does 70w max of 14.4v (about 35rms). Its not really quality but does quite a good job.

Gutted a blown MEI car amp yesterday and found out that it uses the Toshiba TA8210 IC. This amp WAS fully functional when I put it into storage about 7 years ago. Try to connect it up and smelled something exotic. Open it up and saw a blackened resistor...... Will troubleshoot it someday.

check out TDA7350, TDA7370, TDA7560 and siblings.

Tripath also has some nice looking multichannel chips. Some of them are more or less specifically for car audio.

Have a look at http://www.st.com/stonline/products/selector/203.htm

This list contains many ICs amp: check out for the ones with 14.4 V "typical supply voltage" they're right made for car audio;
