## Questions & Answers

**Q: Has anyone tried to mount these on a Harley engine guard?  Any issues?**
A: I mounted these on the engine guard of a Yamaha V-star. It works ok. But volume and clarity much improved when I moved them to the handle bars behind the windshield. When I had them mounted lower,on the engine guard,  to much distortion at highway speeds.

**Q: Would you be willing to just sell the amp part?  Stored over the winter and mice ate through the volume control and some other main wires.**
A: Hello,

I am looking through all of our options, and I did not find the amp by itself. 

Thank You.

**Q: Well this work on my Honda 1100 with a windshield? Are they water proof?**
A: I have this system install on my 2000 Honda VT1100C3 with a windshield it has work great sound is clean and loud, I install the speakers on the engine guard, the amp on the fork bag and the volume on the tool cover.

**Q: I just installed this and one speaker is already blown!**
A: Sometimes they go out and come back in
