Soundmax SX-LX4350.4D – 4-channel amplifier with extreme power and full control

Soundmax SX-LX4350.4D is a powerful 4-channel amplifier developed for systems where both power reserves and flexibility are top priorities. With a massive 350W RMS per channel at 4 ohms, this amplifier easily drives demanding midbass drivers, midrange speakers or complete front systems – delivering control, dynamics and clean sound reproduction.

At 2 ohms, the amplifier delivers 530W per channel, and when bridged it provides up to 1060W RMS x2, making the SX-LX4350.4D extremely versatile. It can be used both as a high-output amplifier for multiple speakers or as a powerful solution for more advanced system configurations where power per channel is critical.

The very wide frequency range from 10 Hz to 45,000 Hz ensures high-precision signal reproduction across the entire spectrum. With adjustable high-pass filter (50–500 Hz), low-pass filter (50–250 Hz) and a built-in band-pass mode, each channel can be easily tailored to the system’s requirements – whether for midbass, midrange or dedicated bass operation.

The SX-LX4350.4D is equipped with a high-level input, making it easy to integrate with an OEM head unit without additional adapters. The wide input sensitivity range of 0.25–8 V ensures stable compatibility with both factory systems and powerful aftermarket sources. With a 90 dB signal-to-noise ratio and low distortion (0.15%), the amplifier delivers clear, controlled and distortion-free sound even under heavy load.

Soundmax SX-LX4350.4D is the amplifier for those who demand extreme power per channel, high flexibility and stable performance in one unit – perfect for serious builds where compromises are not an option.
