## Questions & Answers

**Q: Is there any way to adjust the settings on the amp? It doesn't seem like I'm getting full power out of mine???**
A: I've got two of these installed in the fairing of two H-D. Both have worked great till recently.  
the older one just one day starting putting out about half the  volume it use to.  I connected a different speaker and no change.  I can switch my phone between the two and with the phone volume the same, the newer one is twice as loud.  Is this amp about to die?

**Q: Kindly recommend 6.5 inch powered speakers with bass of correct Watts & Impendance. Thanks**
A: This amp will have no problem driving 6.5" 4ohm speakers if they are in to 50-150watt range.  Remember it is 4 channel

**Q: Can this run 4 80w speakers?**
A: Yes. It will do fine w/ 4 speakers especially if they are low end or factory car speakers. 

If they are aftermarket higher end speakers you may struggle with clean sound at higher volumes...in which case I'd get a better $$ amp

**Q: How long is the wire for the remote?**
A: Well friend it’s about 10 feet long if you’re putting this on your motorcycle I definitely recommend it it’s the best add-on I did my bike I can go 80 mph and here Chris music
