A very complex subject.

Much better to simply purchase a commercial car amplifier.
There are so many available that are quite good, and many many that are very inexpensive too.

There may be some kits too...

One of the problems with car amplifiers is that there is not just a power amplifier, but also a power supply that boosts the voltage up from 12 volts. Much more complex project.

If you really want to learn how to do such designs, then read this forum fully, and read about switching power supplies, and then buy some electronics text books... maybe also go to engineering school too? Seriously.

There is a section here on Car Audio too... maybe post in that one too?

Have fun!
