Hi Mukhalled,
The TDA1521 is able to drive a single-ended 4 ohm load so is able to drive a bridged 8 ohm load to 18W at low distortion or 26W at high distortion with a 22V supply.

Hi Mr. Audioguru,
I've built the amp and it sounds pretty good  ;D. First i would use it in the car but the voltage was not enough, it needs at least 15V  . So i should use it for another application, maybe DVD player or something else ...

Best Regards

Hi,
I thought it would not work at 14,4V, but i tried in the car and it really worked  ;D. It gives 8W to 10W. It's not much for a bass box but it does well  ;D.

Best wishes

Good, you have some bass in your car. ;D
