DS18 Full Range 4 Channel Marine Amplifier 4 Ohm NXL-X600.4D

The DS18 NXL Series was developed for people who want a very small audio footprint that is capable of putting out lots of power and sound in a small and waterproof package. The NXL Series of amps is one of DS18s most efficient lines with great power output while withstanding the elements. These amps come in 1-channel, 4-channel, and 5-channel to help you power a wide array of speaker setups. Being full-range amps, they also can be run on subwoofers, mid-ranges, and tweeters. The high pass and low pass filters will help you tune your speaker choice accurately so you can obtain crystal clarity from low volume levels all the way to the maximum for the ultimate audio experience. All units have stable and reliable 4-layer PCB layouts, IPX7waterproof rating for power sports, an ultra-compact size for easy installation, and audio precision quality control verification. Please see below for more features and specifications.
