Soundstream

Pack a lot of power into a small space with Soundstream's ST4.1000DB 4-channel marine amplifier. Its efficient Class-D design combines stable performance, low power draw, and excellent sound quality into a small footprint that's a great match for boats, motorcycles, ATVs, or any application where space is tight. Built-in Bluetooth lets you play your favorite music directly from smartphones and other mobile devices without the need for a receiver or the hassle of cables and plugs. Whether you're out on the water or up on a mountain, that's a big benefit. This amp works with both factory and aftermarket radios, and quick-disconnect harnesses make the ST4.1000DB easy to install and remove. A subsonic filter eliminates ultra-low frequencies that can muddy your sound, while the conformal-coated circuit board keeps the sound cranking when you're out having fun. The amp includes switchable white and black top plates, so you can choose the look which best matches your vehicle or vessel.
