SONY XM-N1004 4/3/2 Channel Stereo Car Amplifier 70W RMS x 4 at 4 ohms

Automatic Thermal Control
Other amps thermal protection circuits will simply shut down until they're cool. Sony's Automatic Thermal Control circuit actually lowers the output levels to reduce amplifier temperature so your music continues to play.

Efficient Cooling Design
The unique thermal control chassis is designed to circulate air and cool the amplifier for powerful sound output.

High Quality Components
Components such as audio capacitors, power MOSFETs and choke coils are carefully selected for high quality sound reproduction as well as reliability.

LPF Crossover
To get the full benefit of your speakers, you'll need to send them the appropriate musical frequencies. The integrated Low Pass Filter (LPF) sends only the deep bass to the subwoofers.

Single Sided Connections
Single sided connections provide flexible installation and multiple mounting options.
