Hifonics 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

Solid made out of metal

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.

It does not worth the money I spend about $75 I buy those 2 and Only last me about three months and Not counted the one that it came with the amp so total was three

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.

My knob have a shortage in it. I'm currently looking

Canceled order for me
