You cannot get 100Watts from 12volts. It must have a power supply to produce at least +-60volts.

+- 33v ( 66 volts total) gives 125w into 4 ohms
You will need a switching power supply.

it's good information for newbies. Power amplifiers for cars need converter.

In my case I look for some projects where makers resolve switching compatibility between switching converters and commutation amplifier.

thanks
