How to Connect Car Audio Amplifiers to Your Smartphone

If you have an Android phone and a modern car audio system, you can easily hook it up with your smartphone via USB or Bluetooth. The first step is to determine whether your mobile device has a built-in USB port. If it does, you can plug it in and then browse your music library using the Android Media Player or similar app.

If not, you’ll need to get a USB-C cable to connect it. This will enable you to stream audio or transfer data to and from the smartphone and your car’s stereo system.

Some newer cars have a USB input on the dash or under the dashboard for this purpose. Alternatively, you may have an auxiliary input that can be connected to the head unit’s 3.5mm jack.

Before you start, you need to ensure that you’ve got all the necessary equipment on hand (a soldering iron, short length of power wire and a screwdriver). Next, find a suitable ground point on your car’s chassis. This needs to be in a good position and out of the way of moving parts.

You’ll need to sand it so that it has a clean surface and the ground wire can be positioned well. This is essential, as it will help ensure that the grounding circuit is optimised and that there is a good connection between the amplifier and the vehicle’s chassis.

Then, cut a length of power wire that is long enough to reach the fuse block where it will be secured and out of the way of moving parts. Crimp one end of the wire with a ring terminal and then use a bolt that will firmly hold it in place (you can do this without a set-screw, if your fuse block doesn’t have set-screws).

When you have finished, disconnect the negative battery terminal and reconnect the amplifier’s positive terminal. Then, test it to make sure that the amplifier is now able to turn on and provide the necessary signal to your radio. If it does, you’ve successfully connected your amplifier to your car’s system!

If you have an auxiliary output on your radio or head unit, you can connect this to the amplifier’s RCA connectors. This is usually the most convenient option, but it can be time-consuming if you have multiple inputs on your stereo.

For the best results, we recommend using a high-quality speaker wire with a good resistance rating. This will reduce the risk of tripping and causing damage to your radio’s internal components.

Once you’ve got all the components ready, you can complete the installation by following the instructions in your manufacturer’s manual or on your car’s user guide. This should be a fairly straight-forward process and will help to ensure that the new system is up and running properly and safely.

Adding a subwoofer can be a great way to add bass to your car’s music system. However, you should always check with your audio system’s manufacturer before installing a subwoofer. Some models have specific connections to avoid damaging the speakers.
