How To Install Aux Input In Car Stereo?

There are two ways that how to install aux input in car stereo. One is connected directly from the back of an aftermarket stereo receiver. The other way we can install an aux input is from the wiring harness. This option includes our amplifier system to boost the signal strength of the aux input.

RCA-Aux Adapter/Cable

If you want to connect your phone or other audio devices via a cable, then all you need is the RCA-aux adapter. This will work with any cassette deck as long as it has an auxiliary input on its face (it looks like a headphone jack).

The back of this particular model features two sets of three inputs and outputs, one for input and one for output. That means you are able to connect two devices at once, which is a nice touch.

The RCA-aux cable has an integrated circuit chip to ensure maximum sound quality and reduced signal loss. It’s fully compatible with all Apple products, so your iPhone will get full functionality through this adapter (including Siri).

Aux input kits are an inexpensive way to get an aux input in your car. Most installers will charge around $50 for this service if you don’t want to do it yourself. On the other hand, installing the kit yourself only takes about 30 minutes!

You will need to buy an aux input kit for your car; these can be found at any retailer that sells audio accessories. It typically includes the following:

  • Car stereo adapter (X)
  • RCA cable (X)
  • 3.5mm male audio jack (X)
  • 3.5mm female audio jack (X)
  • Wiring clips (+/- 20 pieces or so)

How To Solder the Aux Input

You’ll require some basic soldering skills for this one. If you’re uncomfortable with the idea of doing it yourself, then take it to a professional and see if they want to tackle what looks like an easy project. The results will be well worth their fee in terms of making sure that no one steals your music!

If you want to install an aux cable directly into your car, then you’ll need to do some soldering. You will also require basic tools, including a soldering iron, solder, wire stripper, and wiring clips.

The first thing you’ll need to do is open up the input of your stereo by separating it from the bracket. After unscrewing one screw at the back, gently pull on both pieces of plastic, holding them together.

Taking your RCA cable, strip off about two inches of the insulation from the end that will be plugged into your aux jack. Now slice off about half a centimeter of insulation from the end where you’re going to solder on the stereo adapter. Once exposed, carefully apply a bit of solder to each wire.

FM Modulator

FM modulators are perfect for those that don’t want to go through the hassle of doing any wiring, soldering, or opening up their dash.

The way they work is by sending an FM signal from your aux device into your stereo receiver and changing its frequency so you can pick it up with a radio station.

FM modulators, however, will not work properly without perfect FM signals. If you can’t get a clear signal and you’re getting crackling and interference that won’t go away, we recommend just going for the aux input kit instead.

Mount the Jack & Testify

You can choose where you want to mount the jack, but make sure it’s somewhere that is protected from any physical damage (i.e., don’t put it near a heat source or air vents).

Once everything is plugged in and mounted properly at each end of your new aux input cable, test out all equipment by playing music on your device. Then turn on your car and see if you’ve picked up a radio signal for the frequency broadcast from your stereo to that aux jack.

What is an Aux Input?

An aux input, or auxiliary input, is a device that allows you to connect your audio player with a 3.5mm headphone jack to your vehicle’s sound system. This connection bypasses the factory-installed stereo receiver’s built-in amplifier and speakers with its amplifier and speaker system.

With this setup, you can listen to music from your phone or MP3 player through the car stereo speakers rather than just through earphones plugged into your phone’s audio output.
