About the Alpine RUX-KNOB2
From our tech experts at CEN
The Alpine RUX-KNOB2 is a remote bass level control for Alpine amplifiers. It adjusts the subwoofer gain from 0 to -12 dB from the driving seat, and plugs into the amplifier with the supplied 5 metre RJ-14 cable. It works with mono amplifiers and the subwoofer channel of 5-channel Alpine models.
Who it suits
Anyone with a compatible Alpine X, R, S, V, PDX or MRX series amplifier who wants to turn the bass down for some tracks or passengers without reaching the boot. It suits mono amplifiers such as the S2-A60M.
Our tech experts advise
Check your amplifier is on the compatibility list before ordering. Set the amplifier gain properly first with the knob at maximum, then use the remote only to reduce bass. The two flanges let it mount on or under the dash. Installation is priced per vehicle, so get in touch with your make, model and year.
