## 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
