The S4-100 stands out as a high-efficiency Class D multi-channel amplifier, offering a wide range of tone control options. It excels in balancing deep, resonant low ends with the necessary power for vibrant mids and crisp highs. In stereo mode, the S4-100 delivers 175 Watts per channel across four channels at 2 Ohm, and 100 Watts per channel across four channels at 4 Ohm.

For those seeking more power, the S4-100 can be configured to provide 375 Watts in stereo at 4 Ohm, utilizing two channels. This configuration proves ideal for situations such as driving one S4-100 to each door in car audio competitions or high-end sound quality systems.

To enhance both volume and sound quality, consider complementing the S4-100 with SoundQubed mid-range speakers and tweeters, ensuring maximum audio performance in your car audio setup.

Make the most of the S4-100's features, including high pass crossovers, which enable precise tone direction to tweeters and midrange speakers. These filters not only safeguard speakers from damage but also minimize interference from low-range bass tones.

Moreover, the amplifier's bandpass filter simplifies the process of determining which frequencies are excluded from your car stereo system, facilitating the separation of mid-range speaker tones from tweeters.

Included within the amplifier is a low pass filter, granting you control over the amount and type of low-frequency output sent to your speakers. Furthermore, secure cable connections are ensured by the power terminals equipped with 4-gauge set screws, while speakers connect to the output terminals using 10-gauge set screws.
