Key Features
- 4-channel car amplifier
- 70 watts RMS x 4 at 4 ohms
- 160 watts RMS x 2 at 4 ohms in bridged mode
- frequency response: 10-100,000 Hz
- separate variable high- and low-pass filters for front and rear channels
Sony 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 heat sink that gets rid of the heat that’s generated when you’re pushing your system hard. The Sony’s XM-GS4 4-channel amplifier 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.
