    • 100W x 4 @ 4 Ohms - 100 watts per channel at 4 ohms is more power than most 4 channel marine amps. This amp is perfect for powering the best marine speakers. This extra power means your speakers play louder, with more clarity, and better overall sound quality. There's no substitute for power in the marine environment.
    • Bridgeable with 300W x 2 @ 4 Ohms - The Roswell 650.4 is bridgeable to deliver 300 watts per channel. This amp can power a pair of tower speakers with all the power they need for less money than many of the other high power, 2 channel marine amps.
    • Efficient Class D Circuitry - Class D amps run cooler, are more efficient, and draw less current than Class AB amps. You can play your stereo as loud as you'd like, for as long as you want, on those hot summer days without worrying. In addition, becuase of the efficiency, you can play your stereo for longer while the engines are off before needing to turn them back on to charge the battery.
    • Compact, Stackable Design - The Roswell R1 amps are compact and are designed to stack using their amplifier stacking hardware (sold separately). You can fit more amplifiers in a smaller space while still providing enough air flow to keep the amps cool.
    • Differential Inputs - The RGB LEDs in the speakers can generate noise. The differential inputs help ensure that the noise from the RGB LED doesn't end up coming out of your speakers.
    • Pass Through Outputs - The pass-through RCA output allows you to easily connect to an additional amplifier without necessarily having to run an RCA from the head unit. Instead, the RCA connects from this amplifier to the next, allowing for easier installation and shorter RCA cables.
