Side-X-Sides, golf carts, four-wheeler/quad-cycle ATV’s and more off-road recreational vehicles – PowerSports have become as popular as boats and they need audio equipment that will stand up to the weather just the same. The marine amplifiers we use in our PowerSport builds are not automotive amplifiers. While they will work just fine in a car or truck, they are purposely built to very strict standards that is tried and tested under the most extreme conditions. Sound Wave Customs only carries the most trusted brands in marine amps, towers, sound bars, sub-woofers and receiver/head-units that have been tried and tested under the most extreme of conditions.
