Customer Ratings & Reviews

Very accurate and makes adjusting the subwoofer bass so easy. No more having to play with the audio settings in the radio. Got one for all my vehicles. Plus I like that the bracket comes off and the knob can be double sided taped or the bracket can be flipped around to mount from the top. Another cool feature is that the cord can be unplugged from the knob housing. So if the knob fails, no need to rewire a new one. Just plug the new controller in.

This Alpine Bass control nob works perfectly fine and all my vehicles are in my Ram Pickup truck and my Chevrolet and they all work. I recommend this knob, it's very easy to use. Easy set up and it works great.

If you have an alpine amp with the phone jack for bass knob, this is a must. Have bass level controls from the drivers seat.

This little sucker is very useful if you want to control your bass.

This Alpine bass control knob is perfect for giving you granular control of your subwoofer. This is what you want for adding the right amount of bass kick to different songs. The knob is the perfect size and shape - you might find yourself just holding the knob while you drive and dialing up or down within songs. It was expertly installed to hide into the dashboard configuration. Love this aspect of the car audio system and highly recommend you add one to yours.

Tbh i dont really know exactly what this does i keep it in the middle and i dont hear a difference when its all the way up but if i turn it down it will turn my sub off so i think thats good

This Alpine bass control knob is the best most accurate bass control knob I have used. Also the Alpine bass control knob is easy to use. Alpine electronics products have always been top notch quality.

This help to control the bass and it’ll give your bass level a boost if needed.

This is a must have control the base in seconds for that extra ump.

Did what it was suppose to do, it’s a knob to control subwoofer output

This puts fine tuning your subs at your fingertips. Easy to install and definitely worth the money spent to complete my sound system in my F 150 pickup.

A little too pricey. But you have to use Alpine because others wont work.

Love this amp so small but yet pushes my 12 inch sub hard absolutely buy if u need a new sub!
