The RUX-KNOB remote level controller works with Alpine's mono subwoofer amplifiers so you can manage your bass level from the front of your vehicle. The RUX-KNOB adjusts your amp's level from its set maximum volume all the way down to virtually "off." Since it adjusts level and not "bass boost," you'll maintain the same bass tone as you turn the volume up and down. You can control multiple amplifiers with a single remote by adding a standard phone cable splitter (not included).

Product Highlights:

  • remote level controller for Alpine PDX and MRX Series subwoofer amplifiers
  • adjusts gain from 0 to -12 dB
  • for use with Alpine mono subwoofer amplifiers
  • multi-amp capable (standard phone cable splitter required — not included)
  • 16' connection cable
  • warranty: 1 year
  • Our 60-day money-back guarantee

Used this with a alpine mrx m55. Works very well. Came with more than enough cable and looks great. Great product and fast shipping. Thanks crutchfield

Pros: Worked as described

Cons: None

Great! Just like a volume knob for the bass. If you don't have one of these, the bass can actually ruin a song. This lets you remedy that.

great product

Crutchfield Customer Review (What's this?)

I got this Alpine RUX-KNOB to make it easier to adjust the bass on my amplier. This product works great and is easy to install. Come with plenty of wire to hide it below cars interior. Definitely recommend.

Pros: Mount it anywhere. Easy turn dial. Small and doesn't take space at all.

Cons: None

Icing on the cake

Written By Lw, Normal, Il on Wednesday, September 03, 2014

Crutchfield Customer Review (What's this?)

Just had a major car audio upgrade. Went from factory to an Alpine system. I found myself struggling trying to get the system dialed in. Using an iPod as a primary source can have an affect on sound quality. Some tunes may need a bit more bass, and some may need less. The Rux knob solved the issue. Utilizing the Rux knob with a MRV-M500, I installed it by the center arm rest. So now making any needed adjustments are right at my fingertips. What a huge difference. I love my new Alpine system, the only downside is that I'm putting more miles on my car and going through more gas as a result of cruising around and jamming. Worth it.

Pros: Easy installation

Cons: Wish it was included with the Amp

Alpine gain knob

Written By Anonymous, NOVA, VA on Sunday, August 24, 2014

Crutchfield Customer Review (What's this?)

Works like it should. Adjusts your gain level on an alpine amp to the maximum gain you have set. Could have some sort of indication of where you're at in terms of knob position, tactile click would be nice.

Pros: Adjust amp gain Plugs right in

Cons: No telling what level the knob is at

bad ass base knob

Written By Mark, Graham,WA. on Sunday, June 29, 2014

Crutchfield Customer Review (What's this?)

Super easy install and now an occasional Lady Gaga song doesn't have overpowering bass compared to my 70 rock music, just a quick turn tones the sub up or down for the perfect subwoofer bass.

Pros: Easy to connect. Inexpensive, works great

Cons: None.

Crutchfield Customer Review (What's this?)

Works great! I'm able to control the amount of bass to my subwoofer from the driver's seat. That's important because different sources of music require different amounts of bass.

Pros: Simple and easy to use. Inexpensive.

Small flaw, awesome product.

Written By Anonymous, Fostoria, Ohio on Sunday, December 01, 2013

Crutchfield Customer Review (What's this?)

It works great, there is just a small problem where only like the first quarter of a turn actually changes the bass and there is no real way to tell where your at on it. Other than that it works for what it's intended for and a great investment.

Pros: I can turn the bass down so I don't get pulled over or if I just want less bass(typically not the problem I'm a basshead).

Cons: Only a quarter turn really does anything.

Helps with that extra needed bass for those songs that lack that you know can be there. or to control the 3rd sub. easy install.

A Must For Any Compatible Amp.

Written By B, South Florida on Saturday, August 31, 2013

Crutchfield Customer Review (What's this?)

Combined this with the MRV M500 Alpine amp. It's a must. Simple to wire. Literally Plug it In and place the knob somewhere accessible by the drivers side or head unit area. Great to adjust the bass levels. I can turn it down with the kids in the truck and crank it up on my own. I like a variety of music so you can easily adjust the bass accordingly on the go.

Pros: Easy Install, Gives flexibility to any compatible system.

simple and effective

This does a great job of controlling my sub level remotely. Works like it should.

Pros: Works like it should, makes it easy to fine tune bass on the fly

Cons: Wish it had more resistance when turning knob

Magic Knob

Written By DCS, Macon, GA on Tuesday, July 16, 2013

Crutchfield Customer Review (What's this?)

The knob is a great addition to the MRX-V60, If you have a radio with sub channel control, turn your volume up a little and use the Knob to dial it down. This Knob is an adjustment tool, Not a magic wand. If you are looking for more bass than you have now, don't expect to get if from a resistor. Buy more power and bigger subs. Crutchfield has a great selection. This Knob is great for bass levels that vary from song to song.

Pros: Looks good, Small

Cons: Price

Not Impressed At All

Written By RP709, Waynesboro, Pa. on Monday, July 01, 2013

Crutchfield Customer Review (What's this?)

I purchased this knob for the Alpine MRV-M500 that I already owned, and like the title says I was not impressed at all. I am not writing a long review on this one because there is not much to say, but you could pretty much stop the knob rotation at about 2/3 and it would be just as effective. It does work, on the lower end of the scale but unless you intend to crank your gain up that's about all your going to get from it. I set my amp gains and head unit with an oscilloscope to prevent clipping all around, when Crutchfield support told me turn my gains up to get more range from the knob, I decided to leave it at that. I have been a customer for almost 18 years, and this may be a tainted review, that I doubt will ever be seen, but this product does not live up the Alpine standard that my other Alpine products have set. The "advice" I was given was definitely not what I would have expected from a company that has never steered me wrong in the past. Turning up the gain on an amp that has been properly set, is NEVER the answer to any question EVER.

Pros: Long cable-Heavyweight design

Cons: Poor frequency response-Limited functionality

Got this free on special. Thanks Crutchfield. That being said, its worth the retail price being able to tailor the bass for each style of music. I like a lot of different styles and now I can fine tune on the fly.

Pros: Compact, effective

Cons: Kind of vague control

Alpine RUX

Written By JCW, Horsham, PA on Friday, June 07, 2013

Crutchfield Customer Review (What's this?)

Good stuff - Its nice to be able to control line-level input of the sub.

Not so good stuff: There is no sense of indexing. There is no marking on the knob or dial so there is no way to tell where on the scale the level is set. The maximum loudness adjustment is based on the gain set on the sub. Once the knob is turned to where the gain is maxed, there will be no additional gain as the knob still has farther to travel. This means there is no way to tell with the turn of the knob where max actually is.

Essentially, this is a very cheaply made accessory.

Love it

This is a no-brainer to purchase. I have this hooked up to the Alpine MRV-M500 and I could not imagine my system without it. Simple to get the right amount of bass to each and every sone. Don't know why someone would not get this.

Pros: Easy, total control

Cons: none

Written By JesseM, Davenport, Fl on Monday, April 22, 2013

Crutchfield Customer Review (What's this?)

Bass knob works exactly as it needs to. Installed on an Alpine PDX-V9. Only thing I wish is that someone would start making nicer looking knobs. It seems that all the manufacturers make the same looking ones with not to much thought into the "looks" of them. I have installed plenty of them and not much change in the years. Maybe an LED to display the Alpine logo would be great.

Pros: Simple to install. Does its job.

Cons: basic looking

Bass Head

Written By WiiPlaya, Surprise, AZ on Tuesday, February 26, 2013

Crutchfield Customer Review (What's this?)

Knob works as described. Have it connected to MRX-V70 5-channel amp. It's an excellent control to have because I have the amp connected to my factory head unit and it doesn't have subwoofer control. The installer was even able to install it in an empty slot on my dash. It looks like it came from the factory like that.

Pros: Able to control bass when amp is connected to a factory head unit

Cons: None

Very nice option to adjust amount of base on the fly. Works well with my Alpine MRX-M50.

Pros: Locate where you want.

Cons: Wish it had a stock face mount to allow the knob installation to protrude thru my dash, instead of side mount. Just a thought.
