Boston Acoustics GT-RSL Remote Subwoofer Level Controller

Got a Boston Acoustics GT-RSL remote subwoofer level controller here. It's still in the original packaging, never used. This is the one you need if you want to adjust your bass from the front seat without messing with the amp settings in the back. It works with a bunch of the GT series amps like the GT-2200, GT-4100, and others listed on the tag. Comes with the knob unit and the long cable to run it up to your dash. Pretty hard to find these brand new nowadays if you're running an old school Boston setup.
