Sony XM-GS4 - 4-channel car amplifier — 70 watts RMS x 4 Plays your music loud and clear Sony's XM-GS4 4-channel amplifier will drive your whole system, sending 70 watts RMS to each of your front and rear speakers. 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-GS4 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. More Features You'll find all the connections 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 use the correct high-pass, low-pass, and subsonic filters 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.
