What thumb control interface are you using?

 

4ga hooked to battery. Pretty much as soon as I start rolling down the street.

 

I'm running the hawg wired

 

 

The hawg wired does not have avc

 

Now that you mentioned the avc it is kinda like that but not sure how with the hawg wired which doesn't have that

 

Yup no AVC or Mute function with that interface. Sounds like the amp is going into protection mode. Since your rear speakers aren't fading from the HU, I don't feel like the HU is the issue.
Also take a look at your volt meter while riding and see if it's dropping.

 

Ok. If the amp goes into protect would the speakers still work?

 

Throw the Hawg Wired amp back in and see if you experience the same issue. Sounds like the amp is doing something funky when the volts get up to 14.5. As others said. Going into protect mode maybe? That’s why it’s only happening to the front speakers. Those are the only speakers you have the amp hooked to.

 

Everyone. Thanks for all of the help. It was going into ptotect mode. Tweaked the gains a bit and it seems to have fixed it. Gets loud but speakers sound distorted. I tend to listen to music with bass in it. The hats sound like crap when bass hits. Any suggestions on different 6.5 speakers?
