HFR-31 Bass Gain Knob Level Remote Control and Wire for Select Hifonics Amplifiers

It works for the hifonics amps. The shape of it is really odd and doesn’t let you grab onto the knob. That’s my only complaint

Like others said, it's a weird shape, not tactile effecient. Also will not work with my Brutus amp.

Solid made out of metal

Exact knob that I was replacing. So win win for me

Did not work

The knob works but the design sucks. The front plate is angled and makes it weird when adjusting. They could've just made it flat and functionality would be so much better.

Plugged it in right away when i got it and it didn't work. It kills the sound to both of my subs, then i unplug it and the sound comes back.

I love the power my hifonics amp produces, 3000 watts, I have to keep the gain turned down on the amp otherwise it will definitely blow my speakers, I've blown 2 sets of 15's. However, my issue is with the bass control knob, within a year, it went bad, I went back to the shop that did the in stall and had to buy another one for 50 bucks, 8 months later guess what, this knob is going bad, my opinion is that the knob is not a high quality product and it is not going to last you long, I was always gentle using it, I wasn't grabbing it all the time turning it up and down, it has failed twice and now I have to buy a new one, smh, not fair to have to keep buying a product that keeps failing.
