Sound Storm has always been on the front end of technological advances as they pertain to mobile entertainment. Powerful SSL amplifiers have served as a prime example of these advancements and a have been a strong category in SSL"s line up. We have taken two of the most popular amplifiers in SSL history and upgraded them for marine usage. Building on the popularity of SSL"s marine grade speakers, SSL Marine has expanded the H2O Series to include two source units (H20ML44 and the H20M330) and a marine radio cover (H20MC) as well as two new marine grade amplifiers, the H202.200 and this H204.400. The accurate and powerful amplification of audio signal from this marine grade amplifier is a clean sounding as the amp is clean looking. The H204.400 is the perfect addition to any marine, golf cart, or UTV application for the user wanting high quality sound from four speakers while enjoying the great outdoors.
