The Rockford Fosgate M5-800X4 are an improvement and upgrade based on their Power Mini Marine amplifier the TM400X4AD. It is now waterproof and IPX6 rated. This means that the amplifier is waterproof, but it can't be submerged. You can wash it down hose it off, you just can't stick it under water. The waterproof pigtails and connectors are included with the amplifier as well as the smoked cover for the controls. You must use the cover and the included harnesses to achieve the IPX6 rating. In addition, the amplifier now features "Preset" switches if you are using it with a Rockford Fosgate UTV stereo kit. You can simply turn the "Preset" switch to the "On" position, select the high-pass or low-pass filter, and the amp will be preset to the ideal tune developed from Rockford's engineers.From a power standpoint, the M5-800X4 uses the new CTA-2006, industry standard, Dynmaic Power ratings and proves that this amplifier out performs the traditional bench specs. The M5-800X4 puts out 125 watts of power to each speaker at 4 ohms and 200 watts of power at 2 ohms. This is tons of raw power coming out of a very compact, yet efficient amplifier. Per the CTA-2006 specification, the constant power rating is the wattage for the test bench to compare amplifiers against amplifiers in a test environment. The Dynamic power rating you see below is the real-word, actual-output of the amplifier when connected to a speaker and playing music. Rockford Fosgate has always been conservative with their ratings, now they have an industry standard, CTA-2006 to show and prove the actual output.
These amplififers sound incredible. When you compare the size, output, and price, you will see that the M5-800X4 is one of the best values in all marine audio.
