Please be more specific with your question: The Pioneer AVH-120BT has 2 sets of RCA outputs for operating external amplifiers. They can be setup as front and rear outputs or front and subwoofer outputs. RCA outputs are set up as pairs. Red for the right and white for the left. Are you using the receiver's built in amplifier to operate your speakers? Are they wired directly or through the vehicle's wiring system? Or are you using an external amplifier to power the speakers? Two speakers or 4 speakers? Does your subwoofer amplifier have RCA or Speaker Level inputs? Does the subwoofer have power from the battery? You can find more videos on Pioneer's KZfaq Channel here; kzfaq.info

This is not normal operation for a Pioneer receiver. I recommend to press the receiver's microprocessor reset button. You'll need a paperclip or some other small point to press the microprocessor reset button. You can find the microprocessor reset button on the Pioneer AVH-110BT on the front panel, just below the USB port. Are you using a steering wheel control adapter in this installation? If so , the steering wheel control adapter may be programmed incorrectly and causing the volume to lower by itself.

Yes. You can use all 4 speaker outputs and the RCA outputs running to an external amplifier for a subwoofer at the same time. The product is designed to reliably operate with the speaker outputs and RCA outputs operating at the same time. No worries. Depending upon your amplifier and subwoofer, you may want to run the RCA outputs as subwoofer with a crossover, or if possible to use a subwoofer crossover that may be built into the amplifier.

RCA outputs, are low level outputs designed to be used with an external amplifier. The RCA outputs send the low level signal to the external amplifier and then the amplifier does what is designed to do. It amplifies the low level signal into a signal that can push speakers. You then can hear the sound from the speakers. The RCA outputs are not designed to connect directly to speakers of any kind. The Pioneer AVH-110BT has a built in amplifier designed for operating 4 speakers in your vehicle.

There are a few different ways to solve this issue. The best answer depends upon the best solution for you in your vehicle. I recommend to get a 5 channel amplifier such as the Pioneer GM-D9705 seen here: kzfaq.info/get/bejne/b594mdCUnbfchpc.html With a 5 channel amp, you can run the front / rear / and subwoofer with on amplifier. With the Pioneer GM-D9705 you can run the Full Range Front and Rear RCA outputs from the in-dash receiver directly to the amplifier. The amplifier will pass this signal to the subwoofer output of the amplifier. In a setup like this, I recommend to use the crossovers on the amplifier. A 2nd way to set this up is with an amplifier that has an RCA output like the Pioneer GM-D8704 seen here: kzfaq.info/get/bejne/e5OGlbhzpq3bcX0.html You can run the front and rear RCA's from the receiver to this amp, and then RCA output from this amp to a subwoofer amplifier like the Pioneer GM-D8701 seen here: kzfaq.info/get/bejne/Y7uhZZh41NWUo4k.html or to a self amplified subwoofer like the Pioneer TS-WX1220AH seen here: kzfaq.info/get/bejne/iKySbLSh2Z-zkqM.html A third way to set up a system like this is to use the in-dash receiver's internal amplifier. For example: Your front speakers and your subwoofer are run from an external amplifier, and the rear speakers are run from the receiver's internal amplifier. All of these solutions will work if properly set up.

Please clarify your question. Do you mean the vehicle's steering wheel controls worked with the original car stereo, before you installed the Pioneer AVH-110BT, and now the steering wheel controls don't work with the new receiver? If so, The Pioneer AVH-110BT requires a 3rd party adapter to operate the in-dash receiver through the vehicle's steering wheel controls. Many are available. Here is one possibility: www.metraonline.com/part/AXSWC You can see where the steering wheel control adapter plugs into the receiver in this Pioneer unboxing video: kzfaq.info/get/bejne/qcCih5dmnpqxk4U.html Or, do you mean the Pioneer AVH-110BT was installed and working with the vehicle's steering wheel controls and it has since stopped working. If that's the case, I recommend to press the receiver's microprocessor reset button. You'll need a paperclip or some other small point to press the microprocessor reset button. You can find the microprocessor reset button on the Pioneer AVH-110BT just below the USB port on the front of the receiver. If this does not correct the issue, the steering wheel control adapter wiring may have become loose or disconnected.

When you say " it flickers on" when you start the vehicle, what part are you talking about? The subwoofer? Or the in-dash receiver? Many amp/subwoofers need to be wired directly to the vehicle's battery for power and separately directly to metal for ground. There should be no shared power/ground connection to the in-dash receiver. Are you using RCA wires to carry the signal from the in-dash receiver to the subwoofer? If so, you'll probably need the "remote wire" or Blue/White to switch the subwoofer on and off. The Blue wire with white stripe on the back of the Pioneer receiver, is the system remote lead. It is used to switch on and off external amplifiers and, other parts, you want to switch on and off with the in-dash receiver. The Blue/white is sort of like an On/Off switch for an amplifier. You can learn more about wiring your Pioneer receiver here: kzfaq.info/get/bejne/Y8h2Ztir38e4Y2Q.html I recommend to contact the manufacturer of your subwoofer for help with that product.

Just so I'm clear, there are 2 separate external amplifiers in this system. There are several possible ways to make this work depending upon the capabilities of the external amplifiers. The Pioneer AVH-110BT has 2 pairs of RCA outputs. The simplest way to set this up is running both pairs of speakers from one amplifier. The receiver's front RCA outputs should run to this amp for the front and rear speakers. I recommend a crossover setting HPF of 80Hz for the front and rear speakers. Please note: You'll have no fader in this type of setup. The receiver's rear RCA outputs should run to the subwoofer amplifier. I recommend a crossover LPF setting of 80Hz for the subwoofer output. On the receiver, set the rear output to Subwoofer. This will give you subwoofer controls from the in-dah receiver that effect the rear/subwoofer RCA outputs.

Did you ever get it to work ?

@@jashaunepps1296 What is the model number of your Pioneer in-dash receiver? What is the model number of your Pioneer amplifier?

What is the model number of your Pioneer in-dash receiver? This is usually printed on the face of the receiver near one of the corners. Usually the model number will begin with the letters AVH, or DMH, or AVIC. If you have the receiver's Subwoofer output switched ON, that is very likely all you can do from the receiver to get the subwoofer to operate. Much of the rest is decided by how the subwoofer is wired to the receiver and the power system in the vehicle. Without taking the vehicle apart, it's difficult to tell what may be the issue. When you say the subwoofer is not working, please be more specific with your question. Is this a Jeep factory subwoofer? or a Pioneer subwoofer? or other after market subwoofer also installed by the previous owner? Is there a power indicator LED on the subwoofer? Are there visible controls on the subwoofer or it's enclosure? Similar to what is shown in this video: kzfaq.info/get/bejne/a6h_jNup25_QZZ8.html You can find more videos on Pioneer's KZfaq Channel here; kzfaq.info

When I say it's not working I mean it doesn't play any sound at all and I have no idea if it's hooked up because there's no indication led on it that says that it could be on

@@courtneyroberts1306 Thank you for the additional information. Please read this entire response before you make any changes to the receiver. Here is a Pioneer How To video about the Audio Settings for the receiver: kzfaq.info/get/bejne/d9xygKiTx9yxmKc.html and here: kzfaq.info/get/bejne/kJ5mmbSj3tW2hp8.html The AVH-W4400NEX has a detachable face. You can see it here: kzfaq.info/get/bejne/qrh4i9B2xN7XcXk.html When you detach and reattach the face, or reset the system, you may need a password to operate the receiver. Since this product was purchased from a previous owner, it's possible the receiver is password protected. You'll need that password to operate the receiver if you press the reset button. Unfortunately, it's difficult to give accurate instruction with many variables in a situation like yours. Here are some possible solutions: If the subwoofer is in fact functional, I suspect it is not receiving an on/off signal from the new in-dash receiver. The subwoofer should automatically switch on and off with the in-dash receiver. This is typically done with the Blue/White wire on the back of the receiver. You can learn more about wiring your Pioneer receiver in this How To video: kzfaq.info/get/bejne/Y8h2Ztir38e4Y2Q.html It's also possible, the subwoofer is switching on with the receiver, and is simply not receiving any audio signal from the receiver to playback. An audio signal is sent to the subwoofer through one of two possible ways. 1. RCA connection. You can see that on the back of the AVH-W4400NEX here: kzfaq.info/get/bejne/es1jf7eTzMrDj58.html or 2. through the speaker outputs.

The Red and White jacks you see on the back of the pioneer in-dash receiver are called RCA outputs. The RCA outputs are designed to send a low level audio signal to an external amplifier. RCA outputs are not designed to be directly connected to a loud speaker or stand alone subwoofer. RCA outputs send the audio signal to an external amplifier. The external amplifier then sends the amplified signal to the speakers or subwoofer. You can see the red and white jacks on the amplifier here: kzfaq.info/get/bejne/b594mdCUnbfchpc.html It's a common practice in car audio to use 10-15 foot RCA extension cables to send the audio signal from the in-dash receiver to the external amplifier. However, if your subwoofer has a built in amplifier, and this is commonly know as a self powered subwoofer, a subwoofer speaker and amplifier built into one box, you can use the RCA outputs to send the signal directly to this type of subwoofer. Pioneer makes many different types of self powered subwoofer seen in this video: kzfaq.info/get/bejne/d9Glpst_us_Qhqc.html And subwoofers that require an external amplifier seen here: kzfaq.info/get/bejne/d8yojNaKq9Telac.html You can find more videos on Pioneer's KZfaq Channel here: kzfaq.info

You can see how to change the RCA output setup in this video: kzfaq.info/get/bejne/iq6ohJB-08ibeoE.html Just to be clear, I recommend to run two pairs of RCA cables from the in-dash receiver to the amplifier. And when wiring the speakers to the amp, you should wire one pair of speakers to the "A" channel on the amp, and one pair of speakers to the "B" channel on the amp. With both pairs of RCA outputs on the receiver set to full range output, when you fade you should hear sound on both front and rear outputs.

@@deckerdotto6035 Thank you for your time. I'm pretty sure that my rear RCA jack is bad. Can barely here rear speakers. Just bought the amp everything else is a couple of years old.

It's possible there is a problem with the RCA cable, or trouble with the amp inputs, or the RCA output on the receiver. For testing, please be sure the receiver's Fader control is in the middle. As a test, you may want to swap around the RCA cables at the amplifier. For example, with the system switched off, trade the cables from channel 1 to channel 2 on the amplifier and from channel 2 to channel 1. Power up the system and try again. If you are seeing the same result, I would try a different RCA cable on the channel that is showing the low volume. Also as a test, you may want to swap around the speaker connections, to be sure the speaker cable or the speakers are not the problem component.

It sounds like you'll need to apply the HPF or high pass filter. This will remove the low frequencies from the front speakers and reduce the noise. You can lean about using the HPF in this How To video from Pioneer: kzfaq.info/get/bejne/jqddg891nKu8eGw.html Since you have a subwoofer in your system it's common practice to remove the low frequencies from the other speakers. I recommend to set the HP for the front speakers at 80Hz to start.
