Tweak the subwoofer volume from the driver's seat

The RUX-KNOB.2 remote level controller works with Alpine's amplifiers so you can manage your bass level from the front of your vehicle. This handy little 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).

Q
Does this work with the MRV-F450?
[ Chris  Jun 02, 2019 ]
1 answer
A
Unfortunately, Chris, Alpine RUX-KNOB.2 isn't a compatible option for the Alpine MRV-F450 amp. I did some research on the MRV-F450, and I'm not seeing an option for a compatible remote with that amp. Feel free to reach out to us by chat online, or by phone, we'll be happy to help. 1-800-324-9695

Q
Need a bass knobs that will connect to planet audio big bang 4000 watts amp?
[ Toriano  May 28, 2019 ]
2 answers
A
That bass knob uses a proprietary connection specific to Alpine amps. I don't have anything specific to Planet Audio but if you have it connected via RCA cables you could use a universal level controls like this EFX: https://bit.ly/31q0iFe
[ Cosmo  Jun 10, 2019 ]  Staff
A
I bought it because it was made for Alpine amps. Using it for a different manufacture is taking a chance that it might not work. Check to see if the manufacturer of you amp has an bass controller.
[ BILL  Jun 06, 2019 ]
Q

[ David  Apr 12, 2019 ]

[ Tracy L.  Apr 12, 2019 ]
A
The PWA-S10V uses a MRV-M250 amp which does work with the RUX-KNOB.2
[ timothy  Apr 12, 2019 ]
A
Yes it will, but the Control Knob needs to be paired with an Alpine AMP.
[ Alton  Apr 12, 2019 ]
Q
Can the unit be disassembled for flush mounting?
[ Rodney  Mar 02, 2019 ]
3 answers
A
The Unit comes with two removable Brackets attached to it's sides. They can be removed by removing one screw, each. I mounted the Unit as is, just inside of a compartment opening below the Radio. I don't think you can take the housing off for a flush mount. This is about all that I can assist with regarding flush mounting. Al
[ Alton  Mar 07, 2019 ]
A
The two little L shaped brackets unscrew on each side. But it does not come with any other brackets to mount it with.
[ Alexis  Mar 07, 2019 ]
A
Yes. I've installed mine through the dash from and all that is visible is the knob.
[ Brian  Mar 07, 2019 ]
