The bass knob regulates the frequency blend level in the lower part of the sound range. The subwoofer knob controls the Gain of the signal that runs into the amp. So, decreasing the bass only alters how the treble and bass frequencies associate.
Increasing or Decreasing Frequency
Depending upon the type and genre of your music, most probably, you will only need to increase or decrease the low frequencies without any interference with the high frequencies of your amplifier settings. This is significantly helpful in 99% of car stereos installation. Where the amp is placed in the trunk, you will not be able to change its configuration while driving.

While knowing how to wire a bass control knob, it is also necessary to choose a compatible bass knob for your vehicle. There are various types of knobs available in the market, and the main difference is how they connect to the amplifier.
As you know, car amps come with different connection kinds, and you should look for a bass knob that resembles the connection kind of the amp, i.e., some use RCA cables. On the other hand, others are universal knobs that can connect directly to the amplifier.
Connecting RCA Connectors
An RCA is an Electrical Connector. Its major function is to transmit video and audio signals. Although, it can also be used for the functioning of a DC power connector, an RF connector, or as a connector for loudspeaker wiring.
They are often color-coded like: red works for the right audio channel, yellow works for composite video, orange for the digital audio, green for the center audio channel, and white or black works for the left audio channel.
Length of RCA Connectors
Generally, the bass control knobs arrive with short RCA connectors, and you may feel you can increase the length of the wire by hooking up an additional RCA cable, particularly in case it is at the trunk.
Quality of RCA Connectors
Keeping in mind that you are using RCA to connect the bass control knob, the quality and thickness of the RCA cables also play a significant part in the sensitivity of the bass control knob. e.g., RCA cables should be properly shielded to avoid any sound distortion.
Attaching RCA Cables
Now, when you have the correct RCA wires in your hands. It’s time to attach the (blue & white) signal outputs to the amplifier and next to the RCA (red & green) signal inputs to your car head unit.
NOTE: The color coding mentioned above can vary on the BRAND (may be different), But generally, bass control knobs have a label on the output and input connectors.
Connecting The Remote Turn-on-Cable
A remote wire fixed behind the head unit is called a turn-on-cable. In most car stereos, a blue and white cable comes out of the back of the stereo harness. After turning on the car, this cable gives the amplifier a signal on when to turn it.
If you connect this cable to any other wire in the car with a constant voltage, the amp will stay on even if you turn the engine off. So, it is essential to remember that it should be connected only to the car radio. If you turn off the car’s ignition, the remote wire stops transmitting current. Consequently, the amplifier switches off.
You have to HOOK UP the remote turn-on-cable behind the stereo towards the orange wire in your bass control knob and then connect the blue wire to your amp.
Setting the Head Unit & Amplifier Bass to Medium
Note that you will adjust the bass of your car radio by utilizing the bass control knob and not the amplifier or head unit other than volume. You should set the bass to medium. Yet, to enjoy the best bass experience, it is always recommended to eliminate the sound distortion from the stereo system.
First of all, minimize the Gain in the amp by increasing the volume of your head unit until there is any sound distortion. You can minimize it simply by turning the knob in the counterclockwise direction and maximize it by turning the knob in the clockwise direction.
Can You Use Any Bass Control Knob for Your Amp?
The bass control knobs are universal devices that can work with almost any amp available on the market. Some come with a multimeter to guide you about using the power of cars’ electrical systems. Hence, they function in the best direction when they are from the same brand as the amplifiers.
Knobs and amps may not work properly if they are of different brands. The reason is that some use standard phone jack plugs while others use standard plugs. And also, their signals and circuitry are usually distinct, with fluctuating current needs and voltage levels.
