If you are using the intercom, you may have the VOX set too high, ask me how I know!

 

+1 I would say it is your intercom.

 

The AVC setting will determine how fast the volume will ramp up at a given speed. With the AVC at max, the volume is increasing to it's maximum allowed output at a much lower speed than if you were to set it to half. If at idle the unit is already at a very high volume, the AVC will have little effect. The unit has an anti clipping circuit that will not allow the volume to increase to a point where the audio clipps.

So here is what happens:
1-AVC is set to max
2-At idle, radio volume is set high
3-At 75 MPH, unit is preceived not to be loud enough, so you increase the volume
4-The AVC has alredy maxed out the volume, so it will appear that the volume control has no effect

The radio is actually working as it should. If you're running the stock Harley speakers, there is very little chance the volume at speed will be aceptable.

Intercom being on will not affect the overall volume of the unit. VOX being set high may cause an audio cut out condition, but again, no effect on overall output.

 

I can crank my 06 way up ?

 

O.K. TECH
what you said makes perfect sense. The stock system is just lacking.
Considering the fact that the Ultra Classic is already an ampilfied system, what would be a good fix? It only likes a little bit going as loud as I would like.
Thanks

Best thing I ever did for my sound system was Hogtunes replacement speakers, lower fairing speakers and an amp. Plenty loud at 80+ mph now, even with my loudish exhaust.

 

Mine works exactly as it should and is plenty loud enough through the speakers and I wear a FF helmet. I'd take it to the dealership and have it checked out.

 

1+ on the intercom. I almost made an expensive trip to the stealer until i realized the VOX was wide open. When you stop at the light, There is not any wind noise to "break" to VOX.

 

Speakers...no doubt. Plenty of opinions and advice here on which ones. Ask around. All the aftermarket speakers mentioned here work well and are a great improvement over the stock.....good luck

 

My stock radio has plenty volume at highway speeds (80 +/- mph) with a helmet on. I suspect you either have a problem or it is related to the intercom settings.
