MTX WET75.4 – 4 Channel Class-AB 400W RMS Marine Amplifier
Product description MTX WET75.4:
The MTX WET75.4 amplifier is a 4-channel Class-AB model offering 4x75W RMS power. It is designed to amplify up to four speakers or two speakers and a subwoofer, allowing you to enjoy a powerful and clear sound experience on your boat. Its UV- and moisture-resistant construction allows it to perform in harsh conditions, resisting water spray, salt, heat, and UV rays.
The WET75.4 amplifier features active crossovers with variable high-pass (HPF) and low-pass (LPF) adjustments, allowing you to tailor the sound to your specific needs. Its noise- and noise-reducing construction ensures interference-free audio performance, even in challenging marine environments. Additionally, its stainless steel connectors and moisture-resistant PCB ensure long-term reliability.
