## Description

Product description

Review: great little sub amp - Does a great job of powering a little 8" sub. Probably work for 10-12" also. Small so it fit on a little box and it has built in crossover and external sub gain.
Review: Awesome little Amp - I used this to power my 10" R2D4 Rockford fosgate sub in my Polaris Rzr 1000 (under-dash enclosure). So far, no issues. It has not let me down after the initial 100ish miles on the trails. The bass boost knob is also nice to have.

## Questions & Answers

**Q: Can this get wet?**
A: No.  The terminals and cooling vents are not waterproof.  What makes these amplifiers preferable for recreational vehicles is that they have pigtail connections versus exposed wore terminals offering some protection to liquid splashes, but by no means waterproof.

**Q: is it marine rated?**
A: Yes

**Q: Does this amp have speaker (high) level inputs?**
A: No.  RCA inputs only.  You will need a LOC to convert to low level outputs.

**Q: I have a 2018 polaris with ride command, will this amp connect to the ride command head unit?**
A: Not sure better check with Polaris
