So if you’re having issues with your amp, follow these simple steps to get it up and run again.

We all know how frustrating it is when our special audio equipment isn’t working correctly. And while there can be several reasons why an amp might not be outputting any sound, one of the most common culprits is faulty RCA inputs. The RCA input is the standard audio input found on most amplifiers, and it’s typically color-coded red and white. If one or both of these inputs are damaged, it can cause your amp to malfunction.

A Step by Step Guide on How to Fix RCA Inputs on an Amp

Step 1: Locate the Problematic Input

The first step is to figure out which input is not working. You can do this by unplugging all of the RCA cables from the back of the amp, and then plugging them back in one at a time. If the problem continues, you will need to go to Step 2.

Step 2: Inspect the RCAs

Once you have located the problematic input, it’s time to look at the RCA itself. First, inspect the ends of the cables for any damage or fraying. If you see any damage, you will need to cut off the damaged portion of the cable and solder on a new piece.

If there is no visible damage to the RCAs, proceed to Step 3.

Step 3: Check the Amp’s Inputs

Next, you will need to check the inputs on the amp itself. Then, using a Phillips head screwdriver, remove the screws that hold the plate in place. Once the plate is removed, take a look at the exposed wires.

If the wires are damaged, you need to cut off the damaged part and solder on a new piece. If there is no damage, go to the next step.

Step 4: Solder the Wires

Once you have located the problem and repaired any damage, it’s time to solder the wires back in place. First, tin the end of each wire with a small amount of solder. This will make it easier to attach the cables to the RCA inputs. Now, heat up the soldering iron and feed the tinned end of each wire through the appropriate hole in the RCA input.

Once the wire is fed through, touch it with the tip of the soldering iron to attach it to the input. Use a small amount of solder to ensure that the connection is secure. Repeat this process for all wires.

Ensure That the Connection Is Secure

Next, solder the wires to the RCA inputs. Again, ensure that the connection is secure and no gaps or voids. Finally, replace the plate and screw it back in place.

Step 5: Test the Connection

Now that you have repaired the connection, it’s time to test it out. Connect the RCA cables to the back of the amp and turn it on. If everything is working correctly, you should be able to hear sound coming through the speakers.

If you’re still having trouble, you might need to replace the RCA inputs on your amplifier. You can find replacement parts at your local electronics store.


  1. Check the input voltage of your amplifier. If the voltage is too low, it can cause problems with the RCA inputs.
  2. Make sure that the RCA cables are plugged in securely. Loose connections can also cause problems.
  3. If you’re using an aftermarket head unit, make sure that the ground wire is connected correctly to the car’s chassis. A floating ground can cause electrical issues, including problems with the RCA inputs.
  4. Try a different set of RCA cables. Sometimes, a defective cable is the root of the problem.
  5. If you’re still having trouble, take your car to a professional audio shop for help. They can diagnose the problem and make the necessary repairs.

Do RCA Cables Go to Input or Output on Amp?

If you’re having trouble getting sound from your amp, it may be due to damaged or loose RCA cables. First, check that the cables are properly plugged in and secured. Then, inspect the RCA jacks for any damage or debris. If everything looks good, you may need to replace the RCA cables.

Outputs on an amp are typically used to send audio signals to speakers. If your RCA cables output on your amp, ensure that the correct speakers are connected. Also, check the settings on your amplifier to ensure that the outputs are set to speaker level. If everything looks good, you should be able to hear sound coming from the speakers.

If you’re still having trouble, don’t hesitate to get in touch with the support team for further assistance.

Frequently Asked Questions

Do I Test the Input on an RCA Amp?

The input on an RCA amplifier will vary depending on your speaker configuration and audio preferences. However, it is generally recommended that you test the input before every use to ensure proper connection and performance. This can be done by activating phantom power (if your amp has this feature) or using a voltmeter to measure the voltage at various points along the cable path.

Why is My RCA Not Working?

If you’re experiencing difficulties with your RCA, there are a few common things that could be causing the problem. The first thing to check is whether it’s plugged into an outlet correctly. If it isn’t, try reversing the plugging direction or replacing the cord.

If that doesn’t work, you may need to replace your RCA cable. This type of cable can become corroded over time and cause connectivity issues between your TV and audio/video device.

Why is My RCA Remote Blinking Red?

If your RCA remote is blinking red, it may be due to a number of reasons. The most common reason for this issue is an incorrect cable connection. In order to fix the issue, try connecting the cable directly to the TV and check that the picture quality is improved. If that doesn’t work, you may need to replace the remote control or receiver.

What is RCA Output in Car Stereo?

RCA Output is a connector that allows you to connect external speakers or headphones to your car stereo. It’s typically found on the back of a car stereo, near the power outlet. This connector lets you enjoy the sound from your audio devices without having to use the front speakers or interfere with driving.

Do RCA Cables Affect Sound Quality?

Depends on the type of RCA cables you are using and your audio setup. That being said, a lot of people believe that RCA cables can negatively affect sound quality. This is because RCA cables are designed for use with audio equipment such as turntables, cassette decks, and speakers. They are often made from thinner wire and can cause interference when paired with audio equipment that uses high-frequency frequencies. This interference can cause a decrease in sound quality. If you are unsure whether or not RCA cables will negatively affect your audio quality, it is recommended that you test them out before making any decisions.
