Sony XM-GS400 4-channel car amplifier — 70 watts RMS x 4

Brings you the music
Sony XM-GS100 330W x 1 Subwoofer Amplifier
You'll get 70 watts RMS to each of your front and rear speakers with Sony's XM-GS100 4-channel amplifier driving your system. Or you can switch the amp into 2-channel mode to power a couple of subs with 160 watts RMS each. This compact amp sports a hefty heatsink that gets rid of the heat that's generated when you're pushing your system hard. The XM-GS100 also uses a cooling fan, which automatically adjusts its speed for the heat it detects, ensuring this small amplifier will always produce the power that's expected.

All connections are located on one side of the amp, which makes wiring simpler and neater. The tuning controls sit protected under a cover so they won't get inadvertently moved. You'll find separate controls for the front and rear channels on this versatile amp. You can run two speakers and a sub, for instance, and have the correct high-pass, low-pass, and subsonic filters available to get the tone right. You'll appreciate the bass boost, if you need a little extra punch. Sony protects this amp with a 3-year warranty, and that says a lot.
