These products come ready to resist all the elements, water, dust, and vibrations that the world of motorsports brings.

DS18's MP4TP 4-inch tower pods display our effort to upgrade the durability of roughly used tower speakers. These new pods have a completely redesigned clamping system made for rough use. They can also be mounted easily on any vehicle but shine best on smaller vehicles that see a lot of vibration. The remodeled clamping system ensure longevity and the utmost stability against all elements. These are the go to speakers for crystal clear audio quality in vehicles with limited space.

DS18’s BTRC-R is an easy to use BT remote control that adds BT connectivity to any audio system. This BT remote mounts easily in every application and takes up almost no space. This unit will send out signal to your amplifiers and also give you control over the music being played via BT without having to fumble around with your phone, so you have less distractions.

Finally, DS18 presents the best digital class amplifier that will provide the best performance out of your speaker towers. The DS18 MP.4A is our latest Digital 4 Channel Full Range Marine Amplifier designed to power and lead every product included with the package.
