With no cassette in the deck providing a signal, only your external audio will be going through to the volume knob and then on to the speakers. In that case, you may be able to wire up your auxiliary audio into the cassette module’s audio output, and simply use the existing switches on the deck to select cassette mode.

Install that switch somewhere tidy and the job is done!Īlternatively, you might find that there’s a button on the deck that switches the radio into cassette mode whether or not a tape is inserted. The toggle switch then selects between standard operation, or the external feed.

You can then wire in your new aux cord or Bluetooth input up to the other pins on the toggle switch. Hook the volume knob’s wires up to the middle two pins of the switch, and hook the original stereo feed up to a pair of pins on one side. The easiest is to cut the stereo audio traces or wires going to the volume knob, and hook them up to a DPDT toggle switch. Thus, there are a number of ways you can splice in your own audio on these units. Some kind of rudimentary switching decides whether the radio or cassette signals get to the volume knob and are then passed out to the amplifier section and on to the speakers. In this case, the audio signal flows to the amplifier directly through the volume knob. This normally applies to radio/cassette players from the 1970s and early 1980s that have an analog volume knob on the front. If you’ve got something quite retro, this hack can be very simple indeed. Often it’s as simple as wiring in to the back of the volume pot. Guide 1: Old School Radio/Cassette Decks An old two-knob AM radio from a 1970s Ford Bronco, modified with an auxiliary input.

However, this guide is intended to get you thinking conceptually about how such mods are done, so that you can investigate the hardware in front of you and make your own decisions about how to integrate an external audio input that suits your usage case. Edge cases exist and depending on the minute specifics of how your original car radio works, these exact methods may or may not work for you. This guide won’t cover every stereo under the sun, of course. In the case of a simple headphone jack input, you simply need to wire up an aux cord or 3.5 mm jack somewhere you can get to it, and call it done. The only difference is, in the latter case, you’ll want to buy a Bluetooth module and hardwire it in to the auxiliary input you create, while also splicing the module into the stereo’s power supply. Whether that audio source is a 3.5 mm jack or a Bluetooth module doesn’t matter. To achieve your goal, you need to find a way of injecting the audio signal into the head unit’s amplifier stage, while making sure no other audio sources are getting sent there as well. Whichever way you go, the process of modifying the stereo is largely the same. Cutting off the plastic case can help too.ĭepending on your choice of audio player, you may prefer a 3.5 mm aux jack, or you might want to go with Bluetooth audio if your smartphone no longer has a headphone port. The RCA plugs can be cut off and the module hard wired inside your stereo if you have room. There are two wires for 12 V power from the vehicle, and the audio signal is sent out over the RCA plugs. Fundamentals A simple Bluetooth module designed for wiring into car audio systems. This way, you can pump in the latest tunes from your smartphone without a fuss, while still maintaining an all-original look on the dash. Thus, we’re going to look at how to modify your existing stock car stereo to accept an auxiliary cable input or even a Bluetooth module. Flashy, modern head units can spoil the look of a car’s interior, particularly if the car is a retro, classic, or vintage ride. If you’re an automotive enthusiast of taste, you can’t stand the idea of fitting a janky aftermarket stereo into your nice, clean ride.
