A remote level control lets you adjust subwoofer bass from the driver's seat. Learn how it works, which JL Audio amps it fits, and how to pick the right one.
Quick Answer
A remote level control is a small knob that lets you adjust your subwoofer's bass level from the driver's seat without touching the amplifier. It works by attenuating the amp's input gain, and the right model depends on which JL Audio amplifier you own.
Why You Might Want One
If you listen to different genres of music, the ideal bass level changes from track to track. A remote level control lets you dial back the subwoofer when you're on a call or listening to talk radio, then crank it up when your favorite song comes on. It's a convenience feature that also helps protect your hearing and your speakers by making it easy to lower the volume when needed.
Compatibility Matters
Remote level controls are not universal. The JL Audio HD-RLC works with HD, XD, MHD, and M-Series amplifiers, while the RBC-1 is designed for JD, JX, HX, MHX, and MX-Series models. Using the wrong one can result in no signal or improper gain adjustment, so check your amplifier's model before purchasing.
Common Questions About Remote Level Controls
- How does a remote level control work?
- It connects to the amplifier and acts as an attenuator on the input gain. Turning the knob adjusts the overall level of the amplifier from the driver's seat, which effectively controls the subwoofer's bass output.
- Which JL Audio remote control do I need?
- Check your amplifier's model. If you have an HD, XD, MHD, or M-Series amp, choose the HD-RLC. For JD, JX, HX, MHX, or MX-Series amps, choose the RBC-1. Using the wrong model may not work at all. Write down your amplifier model number before ordering.
- Can I install it myself?
- Yes, in most cases. The remote control connects to the amplifier via a supplied cable, and the knob can be mounted under the dash or in the center console. If you're not comfortable with basic wiring, a professional installer can do it quickly. Route the cable away from power wires to avoid noise.
