That's OK, my spanish is bad
I found this for you:
http://www.google.ca/search?hl=en&ie=UTF-8&safe=off&q=mosfet+car+amp+projects+100W&btnG=Search
The reason I refer you to Google, is you can do a search in spanish
Good luck!!

Spanish language??? Oh my god!
That´s Portuguese language Geek , the native language of Brasil is portuguese, spanish is very diferent...
j.p-ni-, here have many mosfet schematics for home, for car, I don´t no, maybe, if you search on google...: http://www.audiofanatic.it/Schemi/Tipo/Stato_solido/finali/Schemi_finaliSS.html
Cheers

EEEEEEEP!
You can find link below with power amplifier (opamp at the input stage & complementary pair of MOSFETs at the output stage). Unfortunatelly, pages are in Polish. In the third link you can find a PCB layout. At the bottom you can find the specification of this amp. If you will be interested in, mail me and I try help you.
