You can control your Sound Ordnance B-8PT powered subwoofer from the front seat with this remote control knob kit. This wired remote adjusts your amp's level from its set maximum volume all the way down to virtually "off." Since it adjusts the amp's level and not its bass boost, you'll hear consistent bass tone as you lower and raise the volume.

Product Highlights:

  • remote level controller for Sound Ordnance B-8PT powered subwoofer
  • 14' connection cable (RJ-14 plugs on each end)
  • warranty: 1 year
  • Our 60-day money-back guarantee

Crutchfield Customer Review (What's this?)

It didn't work on my old Rockford Fostgate amp. I plugged it in an the bass was always full volume. Ended up reselling it.

Pros: Knob feels nice and smooth with clicks. Compact in size to hide anywhere.

Cons: Doesn't work on older amp models.

Crutchfield Customer Review (What's this?)

I agree whole heartedly with the other review. It is indeed a knob, that turns the subwoofer gain up and down. It does this job quite well, almost like it was the only function it had to perform. The cable is sufficiently long (RJ11 phone line) that it can be run from trunk to drivers seat if required.

Pros: It does it's job well

Cons: To nitpick, I imagine it could be engineered to be smaller, but it's a good size. Smaller than a jeopardy buzzer, larger then a cricket.

Its a knob!

Crutchfield Customer Review (What's this?)

This knob turns the subwoofer volume up AND down. It's truly amazing.

Pros: Turns it up. Turns it down.

Cons: Doesn't light up with LEDs or some other totally awesome but incredibly unnecesary thing.
