I have a Non-Bose, 1 CD/MP3 2008 stock unit in my GT3. I have noticed a recurring issue of my bass cutting in & out and its getting worse.

Has anyone else had this problem or heard of it?

You sure this is not the ACL level setting, it makes your radio sound volume go up and down according to your speed.

Check your Manual , it is easy to disable.

I should have also put the ACL on there also. I have tried this with the ACL level turned off and on ACL 3. It also does it when I am not even moving.

Didnt see this thread before I added this. Thanks.

Looks like others have had the same problem. My 12 year old Nissan Pathfinder stereo doesnt have this issue so my 1 year old Mazda shouldnt either.
