Review: Bought this alongside CT sounds wiring kit. Absolutely the best combination of sound equipment I’ve ever owned. This 3 wire set up works great. I tied into my stereo wiring harness and it’s been just fine! I think it’s a great value for something so amazing.
Review: Works exactly as described....though it is very very bright at night. I will certainly have to put something over the display such as tint if I have some left. It was shipped out quickly and was fast shipping. Couldn't ask for anything more!!

## Questions & Answers

**Q: I need the one that has the telephone plug in the back where can i find it**
A: You have to realize that the telephone style plugs are not standardized. Each amp company can use any combination of wires to do any number of things. If you don't use the controller that's designed for that particular amp you could easily fry internal circuits and permanently damage your amplifier. So only use the base knob designed for your specific amp.

**Q: will this work on a1200 watt Rockford fosgate class D mono amp i cannot find a bass knob that works**
A: I would say that it will probably work. It plugs into your rca cables and has another set of rca out to run to the inputs on the amp.

**Q: How long are the wires for the knob? Is it long enough to wire from the trunk to the front of the car? If not what wires would I need to get?**
A: Run rca from head unit to knob mounted near the driver.. Then run rca to the rear..If you are using a factory head unit, You will just need to run longer rca to the frint, then back to amp.

**Q: Does this knob have any "knotches" or "clicks" in its rotation? Say like at the half way point? Or is it just smooth across it's entire range?**
A: It's smooth across the rotation. It does push in to turn it on or off.

### ⭐⭐⭐⭐⭐ Review
*by J***L on 21 January 2021*

I was a somewhat skeptical the sound would reduce in volume or quality before I purchased but neither of those fears came true, this thing is great. The voltmeter seems accurate but the hole in the side has a pot to allow you to calibrate it, if needed. The knob is not loose, it has a "dead zone" where it doesn't turn the control its attached to. It will definitely not get turned by loud music or bumps. The power LED is ridiculously bright, and I knew that from the reviews, so I hid it inside of a 1-din pocket with a flip-up door, available from Subaru for Foresters but made to work in my WRX. I like that it says "On" when powering up and "Off" when powering down, either by ignition or by the button on the dial. I pulled it open and was surprised to see its chip controlled on a high quality PCB. The wires are tiny and the RCA's aren't the best in the world but they do what they need to do. All of the wires are on JST type connectors to attach them to the PCB so I could probably replace all of them if I wanted to. I got a 4 wire connector that had matching wire colors and put that on the end, soldered and shrink wrapped. The car side of the connector was soldered into the wiring harness and the remote wires were crimped, being assembled in the car. I used a short 1.5' RCA to go to the radio. Makes for a very slick knob that does everything its intended to very well.
