The Rockville PS40 is a 4 channel amplifier that is perfect for any powersport application like UTV, ATV, motorcycle, etc. It will deliver 85 x 4 watts RMS @ 2 ohms. We dyno-test the amp to make sure you get the power we promise

This amp is IP65 which means even if you submerged it in water for a few seconds it will still function fine. This means you do not need to worry about your amp breaking when you spray down your vehicle. The amp also has waterproof silicone covers over the control panel and inputs to give additional protection.

The built-in Bluetooth is great because you do not even need a head unit or controller. You can just install this amp and wire it to your speakers and then Bluetooth your phone to the amp.

This amp is super compact making it easy to install into tight spaces.
