Down4Sound's Universal Car Audio Bass Knob is now available in VERSION 2!

We have upgraded the whole manufacturing process this time to being injection molded & we incorporated a volt meter as well!

The finish is super smooth and soft to the touch.

Volt meter hook up:

  • Red wire- Constant 12v power
  • Black wire - Ground
  • White wire - 12v acc / remote turn on

Still made with the best internal parts and Rca's on the market. 
The Rotating Subwoofer is made from very strong plastic.
This is one of, if not the best universal bass knob / remot with Rca's on the market.

It will work with any amplifier that requires RCA inputs.

    It’s a really cool looking bass knob, the only issue is that it has a few scratches, other than that it’s great.
