How to Nab the Right Radio Control Knob
More often than not, the importance of peripheral car parts such as the radio control knob is understated if not completely ignored. We only realize its importance after noticing that it's broken and the entire car stereo becomes useless altogether. Don't worry because among thousands of replaceable car parts, the radio control knob is probably the easiest one to change. But, replacing the knob isn't really the problem ? the problem is in choosing the right knob for your car stereo. Fortunately, here's a guide that will help you explore some of the most common radio control knobs, and hopefully will help you decide on which one to buy.
Compared to standard models of radio control knobs, the collet knob is designed to integrate function and versatility into one. The collet knob has a soft touch finish unlike other types of control knobs that have hard surfaces. In addition, the collet knob uses polypropylene and thermoplastic elastometer in order to mold the markers rather than simply printing it. Commonly, collet knobs are colored in black and white which interchanges between the marker, the body and/or the surface.
In terms of durability, the push-on knob is the name of the game. Push-on knobs are created using a two-shot molding procedure that allows creating the two parts simultaneously without the need for assembly. It has a hard touch finish due to polypropylene content that gives it more durability compared to other knobs.
The slider knob is specially designed to provide the user with the ease of control. However, while a slider knob is perfect for that aspect, it takes a lot of space. This is because the slider knob requires occupying at least three inches of a horizontal line to set the control parameters and visual aids. Moreover, slider knobs are available in soft touch and hard surface models.
Fixing a Broken Radio Control Knob
Since the 1920s, automobile radios have developed from the simple AM/FM devices to the complicated compact disc players installed on most vehicles nowadays. Because of its complex evolution since it was introduced to vehicles, automobile radios become harder and harder to repair every year. Thankfully, there are still a few parts of the automobile radio produced today that can still be easily repaired without professional assistance. The radio control knob serves as a channel selection device that allows you to change frequency tuning whenever listening to the radio. Other automobile radios also have control knobs for volume, bass and output tuning. Fixing a broken radio control knob is an easy task for beginners ? all you have to do is gather some needed tools and follow these few simple steps we enumerated for you.
Difficulty Level: Easy
Tools you'll need:
- Phillips screwdriver
- Allen/standard screwdriver
Step 1: In order to install a new knob, remove the car stereo from the dashboard mount using the screwdriver that fits your car's specifications. Insert the tip of the screwdriver to the top or bottom grill and turn it clockwise until the car stereo pops out.
Step 2: Depending on the knob you are replacing, locate the output RCA cable connecting the broken knob to the stereo. Disconnect the output RCA for the former knob and join the output RCA to the input RLC of the new knob using a pair of pliers and a standard screwdriver.
Step 3: Plug the car stereo back to its dash mount and make sure to place the wiring back in place before sealing it off again.
Step 4: Turn on the radio and test if the knob works. If it's a volume knob, set it to a normal listening level slowly increasing volume and back to normal again. If it's for channel selection, test for channel accuracy.
