Ok, I have spent several hours reviewing this forum and it appears that all the plug and play head units DO NOT have AVC... The only option I see is using the Biketronice module on an aftermarket radio. I don't believe these modules are plug and play but require you to cut your OEM harness, strip the ends and terminated into the module. Does anyone know of a head unit that has AVC and does require splicing into the existing harness.

The bike is a 2006 Streetglide with hogtune speakers and hogtune tweetbar. I like the sound and have no need for all the other bells and whistles on some of these head units. This has been my set up since 2008. I plan on sending the unit to Iron Cross for repair if I cant find a replacement with AVC.
Thanks
Drew

 

Call Biketronics. They will hook u up with "plug and play."

I'm in no way advocating the use of AVC as it can blow shix up if it's not set up properly, but BT will set u up.

Don't forget about the forum discount.

I've always been curious as to why the AVC is a no no when it comes to aftermarket amps. I used mine when it was stock and liked it. Though I never set it to turn up too loud, but it was nice having it turn down for you when stopping at lights. I guess I dont see that being any different than me manually turning the volume up and down as needed.

 

Because you set your max gains with the bike sitting still in the garage. Then you get out on the road and you want to crank up the volume. If you have the AVC on you are now sending more power to the amp than it is set for causing your amp to work harder. That is a very simplistic answer but hopefully you get the gist.

 

I do get the gist. But again not sure what the difference in more power to the amp via volume control versus AVC.

Turning up the volume via thumb control = more power to the amp

Turning up the volume control via AVC = more power to the amp.

As long as the AVC isn't bumping the volume up past the point of distortion, it should be the same.

Mine is off....has been since i installed the first amp I had.

After an amp install, you are holding your max volume back, before distortion. (Typically 3/4 volume)

If riding at 40mph at 3/4 volume and you accelerate to 70mph, your are now going past your amp installed max volume. Essentially overdriving the speakers and introducing distortion.

 

Ahh, ok that makes more sense. The AVC volume changes are relative to the current volume. I thought the AVC was set to two specific values. The low side would reduce volume to a specified volume and the high setting to just a specific high volume level regardless of the volume I was listening at.
