Designed to stand up to the environmental conditions you are likely to subject them to. With corrosion resistant stainless steel hardware and two-part epoxy coated circuit boards, these units are designed with you in mind. Whether on the lake, on the road or in the back woods these amplifiers are ready for an adventure.

Rockford Fosgate PM100X1

The Rockford Fosgate PM100X1 has a IPX6 Water Intrusion Rating meaning that it has been tested in multiple aquatic scenarios and proven to withstand against water damage. Water projected in powerful jets from any direction shall have no harmful effects.

Rockford Fosgate PM100X1

Rockford Fosgate's proprietary ecoPUNCH technology is a solution that features the clarity and hard-hitting dynamics expected in a form-factor that's lighter, costs less, is easier to integrate, and consumes less power than comparable systems.

Sony MEX-XB100BT

"FreeLoad" technology is a small amplifier that does not require a B+/GND connection to produce power. FREELOAD technology not only takes in the audio signal from the source unit to amplify, but also to power the PM100X. The result is more consistent output power and higher output power when needed.

Rockford Fosgate PM100X1 with FreeLoad Technology

These amps (sold as pair) are amazing. Allows me to add more power to a Bose system that can't be modified in a 2016 MX5. The build sheet said 74 watts into 4 ohms and 117 into 2 ohms. These amps are small, compact and light. Marine grade is more than a plus, because it allows worry free mounting in the door. One amp in each door. No power wire, just a three wire hookup in door: ground, postitive, and negative. Rockford Fosgate's BTL freeload technology is amazing, uses the current that powers the speakers to power the amp; The amp is the size of a pack of cigarettes, largest part of the amp are the capacitors that store current for musical peaks. I am using PPI 356CS (bought from sonic electronics 10 years ago) speakers and have yet to clip the amps at high volumes. Easy to hook up and install. Truly amazing technology. If you have a stock audio system like Bose that is difficult to modify, these are the answer. Amazing sound, completely transparent. Can't say enough about them. Thank you RF for making the Bose system sound like an expensive system with full sound in a noisy convertible. I hope that RF can also perfect the technology to power subwoofers too.
