Know before you buy
While it is optimized for subwoofers, this is a full-range amplifier. It is capable of driving high-performance mid and high-frequency speakers if you need a versatile solution for your marine audio setup.
R.I.P.S. (Regulated Intelligent Power Supply) technology ensures you get a consistent 750W of power regardless of fluctuations in your boat's battery voltage or the impedance of your speakers. It keeps your audio output stable and clean even when electrical conditions aren't perfect.
The amplifier uses RealSink™ heat sinks for passive cooling and features Advanced Rollback Protection. If the unit gets too hot, it will automatically and temporarily reduce its power output to protect the internal components until it cools down.
It is built with durable finishes and stainless steel hardware to withstand the marine environment, but it is not waterproof. You should still mount it in a dry, protected area away from direct water spray or submersion.
You must use at least 4 AWG copper wire for both the power and ground connections. Using the correct gauge is essential to ensure the amplifier receives the current it needs to perform reliably.
Yes, the amplifier features switchable input voltage ranges to accommodate different signal strengths. You can set it to Low (200 mV - 2 V RMS) or High (800 mV - 8 V RMS) to match the output of your specific head unit.
