## Questions & Answers

**Q: okay I have a Street Glide 2015 special dose any one know if the Hertz 6 1/2 mpx pro will fit  in the faring without hitting the grill in side**
A: On my 2017 Street glide I had to mount them inside the speaker pod, which takes some minor cutting and fitting (videos on YouTube). I still had to buy after market grills because the speaker was touching the factory grill. The factory grill is too thick because of the plastic backer and they're made with some cheap  fabric material.

**Q: How to tone down the tweeter? Aside from adding a resistor, any tips on toning down the tweeter? May need to get components to have -3db control**
A: I added a Rockford Fosgate DSP Processor between my amp and speakers.  I give lots of control over all ranges...

**Q: What’s the RMS watts on these hertz speakers**
A: 100 watts

**Q: Does it come in a pair or single?**
A: This item is sold a s pair, thank you.
