## Questions & Answers

**Q: Has anyone tried to mount these on a Harley engine guard?  Any issues?**

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

Thank You.

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.
