You want to rock out on the water? Wet Sounds' Sinister(tm) Series SDX6 amplifier will send six high-performance speakers 185 watts RMS each, giving you some serious sound for your aquatic fun. Or, you could power four speakers with 185 watts RMS each, then bridge two channels to drive a subwoofer with 585 watts RMS. You can configure this amp to run almost any setup - from multiple speakers and tower systems to high-performance marine subwoofers. A stereo/mono switch on each channel pair ensures you can send a full musical mix to whatever speaker or area of the boat you want. Tough and efficient A conformal-coated PCB circuit board, a sealed salt-water resistant heat sink, and stainless steel hardware ensure that this amp will stand up to salt, spray, high temperatures, and continuous high-volume playing. This amp uses Wet Sounds' patented MAXED(tm) power supply technology to achieve high power efficiently, without straining your boat's electrical system. An onboard microprocessor monitors voltage, temperature, and much more to protect the amp from damage. Tone controls that matter High- and low-pass filters allow you to fine-tune the sound for your speakers and subs. A variable bass boost on Channel 1-2 lets you add boom when you're driving a sub. The power, speaker, and input connections are conveniently located on one side of the amp, while the top-mounted controls are protected by a removable cover. And you can set the Wet Sounds logo badge to glow either red, white, or blue, to reflect your particular party mood.
