My remote next to me when i am driving sucks and i have to mash the rubber buttons to adjust the volume and it has become somewhat irritating when pulling riders. I have heard of this HSE that adjusts to the throttle so when you throttle up the music gets loud and then mutes when throttled down. I am asking to see if any of you have installed and if so do you like it and how many beer installation is it? I believe it goes between the headunit and your amps??
