TDA7850 Internal 4 x 50W Quad Bridge Power Amplifier

$ 73.45

The new TDA7850 internal amplifier provides a powerful, yet compact, solution for your car computer project. There is now no need for expensive external amplifiers or running long audio cables or power extensions though out your vehicle.

This Amplifier fits perfectly inside our Nano ITX Enclosures.

Measuring only 70mm x 55mm x 30mm, it is capable of powering 4x30 Watts (RMS), VDD=14.64. Sound quality rivals that of most aftermarket head units. This amplifier uses a similar chip to the amplifiers found in Pioneer, Panasonic, etc.
