SoundQubed S4-100 Multi-Channel Amplifier - 4-Channel Car Audio Amp

The S4-100 is a high-efficiency Class D multi-channel amplifier that caters to the needs of car audio enthusiasts, whether for daily driving or competition builds. This versatile power amplifier offers a host of tone control options, delivering deep and loud low ends while also providing ample power for mids and highs.

With its impressive power output, the S4-100 can deliver 175 Watts RMS per channel in stereo on four channels at 2 Ohm, and 100 Watts RMS per channel in stereo on four channels at 4 Ohm. For those seeking even more power, the amplifier can be run in stereo at 375 Watts at 4 Ohm on two channels, making it an ideal choice for driving one S4-100 to each door in car audio competitions and sound quality systems.

To ensure precise tuning for your car audio setup, the S4-100 features adjustable low-pass and subsonic filters, as well as high pass crossovers.

The multi-channel amp's bandpass filter makes it easier to define the frequencies eliminated from your car stereo system on the high and low end, enabling you to separate the mid-range speaker tone from your tweeters.

The power terminals secure your cables with 4-gauge set screws, and the speaker connections utilize 10-gauge set screws, ensuring a secure and reliable installation. With a compact form factor, the S4-100 offers multiple mounting options, saving valuable space in your daily driver.
