This harness combo allows you to retain your factory amplifier, subwoofer, door speakers and tweeters.

Our harness combo utilizes RCA connections to send a low level (0v-4v) audio signal from the back of your new aftermarket radio to the factory amplifier in your Acura RDX. Our harness combo integrates with the factory amplifier to keep all of your speakers working. If you wish to keep the factory steering wheel controls with your new aftermarket radio you may also need the AXSWC steering wheel control interface. If you do plan to retain your steering wheel controls, you will only be able to keep volume up, volume down, next, previous and mode. You will not be able to keep the call control buttons. When you replace the radio you will lose the factory hands free functionality and the factory XM radio along with the factory compass. The factory audio-HVAC display shows the audio and climate control information, if you replace the audio unit you will still be able to control the climate but you will not be able to see the information. You can still change the temperature and the settings but can’t see the current temperature or blower location/speed.
Please verify your factory amplifier is working and you aren’t having any volume issues before replacing the factory radio. If you are having volume issues please check out our plug and play amplifier. If you wish to bypass the factory amplifier in your Acura and power your speakers directly from your aftermarket radio check out the amplifier bypass.

If you have any of the following Acura’s including the Acura ILX, Acura TL, Acura MDX, Acura RDX, and Acura TSX from years 2007 to 2014 with the ELS system you can now replace the factory radio and keep the factory amplifier in place to power all of your speakers. The factory amplifier requires digital volume control which is achieved with our interface and a dedicated external volume knob. Instructions
This interface will come with proper connector for your vehicle and you will have to connect two additional wires. You will have to connect the red wire to accessory power and the black wire to ground. This interface will plug in behind the radio. We will reach out via text to confirm all the details so please use a valid phone number when ordering.
This integration does not keep the factory navigation working. You can retain your navigation if your car has a DVD based navigation unit somewhere in the car. The 2010 and up Acuras all have Hard Drive based navigation so you will not be able to retain it. You can only retain the navigation in some 2007-2009 Acuras. You can not retain the navigation in any 2009-2013 Acura TL.
This interface allows you to control the volume of the factory amplifier. This interface does not allow you to control balance and fader. You can change the EQ on the radio for the desired sound but the factory amplifier will still keep the factory crossovers in place. The factory amplifier only uses the FL and FR audio outputs of the aftermarket radio and expects the voltage of the RCAs to be between 0v- 1.3v. This means this interface can work with almost any aftermarket radio. Along with this interface you will still need the other necessary harnesses to install you aftermarket radio. You will not have the ability to fade the audio between the front and back but you can balance between left and right.
Do you want to add aftermarket subwoofers to your Acura TSX? If you have a TSX from 2004 to 2008 that uses the factory amplifier (they all do unless you removed it) then you can use this t harness to get a low level sub signal (0v-3v) from the factory radio and the switched 12v amp turn on as well from one location without removing the radio.
This harness connects to the factory amplifier plug and gives you a pair of RCA out (RL and RR) and a remote lead (12v power) for your aftermarket amplifier. It makes adding a dedicated subwoofer amp easy and you can use it with the factory radio or an aftermarket radio if you use one of our DIY or plug and play harness to install your radio.
This is a low level signal with 3V of output at max volume. This harness will be all you need you will not need a line out converter.
If you are using an aftermarket radio installed with our accessories then this harness will allow to add an amplifier for subwoofers without removing the radio.

Looking for a replacement sub woofer for your Honda Accord or Honda Civic that fits in the factory location? This is it! When replacing your factory subwoofer the three main challenges are that it must be a free air subwoofer as the factory subwoofer is not fully enclosed, that it must be 8 inches and not exceed 6 inches in depth and that its final impedance must be two ohms. This subwoofer meets all of those criteria and fits into the factory location with the use of an adapter bracket. If you are replacing the subwoofer in the 2008-2010 and 2012-2020 Honda Accord you might need to modify the factory opening by bending the metal to help the subwoofer wiring fit into place. If you are installing this subwoofer in a 2006-2011 Honda Civic you will have to make modifications to the metal around the subwoofer. This subwoofer does not work on the 2006-2011 Honda Civic Coupe (2 Door Models).
This replacement sub works with the factory amp but can be amplified with other amplifiers if wanted. We recommend you sound deaden the rear deck and the rear deck cover if you will be using another amp to power the sub. This sub can handle up to 150Watts RMS. This subwoofer will not rattle your car apart but it will give you better bass response. This subwoofer works best with one of our plug and play amplifiers or a aftermarket amplifier to power it.
This package comes with the adapter needed to mount the aftermarket sub in the factory location and a harness to connect to the factory subwoofer connector so the install is as easy as possible. Once a subwoofer is installed and powered on it is not eligible for return only exchange.

If you are looking to upgrade the factory amplifier in your 2008 to 2016 Honda Accord this amplifier is a great upgrade that doesn’t require permanent modifications. This amplifier is fully plug and play, there is no wiring necessary to install it. This amplifier can replace your Hondas’s failing factory amplifier and doesn’t require you to install new speakers. Your Honda Accord must have a factory amplifier for this amplifier to work. If you have the factory rear subwoofer then this amplifier will work for your car. You can also use this amplifier to power aftermarket speakers. This amplifier provides 80 watts of output per channel @ 2 ohms and 40 watts of power @ 4 ohms. The subwoofer portion of this amplifier can provide up to 200 watts of power to a 2ohm subwoofer or 100 watts of power to a 4ohm subwoofer.
This is a class D amplifier that produces 80 watts of power for each door speaker 200watts of power for the subwoofer at 2ohms. At 4ohms this amplifier produces 40 watts to each door speakers and 100 watts to the subwoofer. Your factory amplifier has a rough output of 20 watts per door speaker and 40 watts for the subwoofer. This amplifier theoretically will produce either double or quadruple the power of the factory amplifier resulting in a system @2 ohms that will sound almost twice as loud as the factory amplifier.
When installing the amplifier we also recommend replacing the factory subwoofer at the same time. The factory subwoofer works with the PNP amp but it will require that your turn the amplifier output down significantly leaving a ton of power on the table. If you are planning to also upgrade the speakers we recommend using 2 ohm speakers from companies like JBL, Infinity, Powerbass, Focal or Audison. Two ohm speakers will allow you to get the most power/volume from the new upgraded amplifier. You can view our speakers here. Also if you are upgrading the subwoofer you want to look for an 8 inch free air capable subwoofer or use the subwoofer output of the amplifier to power an enclosed subwoofer that you can store in the trunk. You can view our subwoofers here.
This package is not meant for bass heads who want to shake the neighborhood when they drive by, it is for someone who wants a balanced audio system with great bass response. This upgrade will make your car noticeably louder and you will feel the bass. Installation is easy and the system comes preconfigured depending on your selections.

When applying sound deadening material to metal surface you need to apply pressure against it so that it sticks properly. This pressure is normally applied with a roller like this one. This roller is the perfect size to apply sound deadening material in your trunk or door panel without any issues.
