Hi All

I'm looking for a 12volt 100w RMS mono or stero ampliflier schematic?

This will be my first amp build. All help will be much appriciated?

Regards,

you can use THİS İC: TDA7560. it is 12v 4x55w very simpe ic. or you can TDA1562Q it is 70w mono, you can make double 1562, you get 2x70w easily or 4x55w 80w peak with TDA7560. I'm sending some samples. and TDA 1562 is working in chass H...

Hi There,

Since you posted this in the car audio section of the forum, are you looking for just a regular power amp to deliver 100WRMS, or a car amp with SMPS that will take the 12VDC from a car, generate the +/- voltages for the amp, plus the amp circuits to then make the wattage?

If you're looking for a car amp, I've attached two schematics from a Linear Power car amp. It's a 1502, 75WRMS per channel car amp and the power supply. The power supply is capable of 300+ watts, so it would just be a matter of a few extra secondary windings and higher voltage caps, plus an extra pair of output transistors and this could easily be a 100WRMS/channel car amp with excellent sound quality and dependability.

Let us know if this is what you're looking for, or if you have any questions about the amp or power supply I attached.
