need advice/guide to making 12v boombox

[ramanta]

hey guys i want to make boombox using 12v sla batteries, here is the diagram that i make

An externally hosted image should be here but it was not working when we last tested it.

i want the specification exactly like my drawing
- one amp each channel (modular what its called, isn't it?)
- a subwoofer amp with a switch (so i can disable or enable it for extra bass)

what i need to know is what IC should i use for the fullrange and for the subwoofer
i prefer some valuable and easy-to-get chips with decent (or slightly haha) sound, and of course, could be run using 12v sla batteries
it would help if you could give the diagram and pcb layout too.. thx sorry for my bad english

A switching type (ClassD) will use less battery power.
Very high efficiency speakers will use less battery power.

thx for the reply Andrew, but what IC do you recommend? could give me the diagram, pcb layout and wiring as well?

Most class D ICs are surface mount and are not trivial for the beginner builder. They make ready to go boards for what you need. A little searching and you should find what you need.
