Now you’ll get a rough idea of how to install a subwoofer to a factory stereo. But that’s not enough; since it is a complicated task, you have to be aware of each detail before moving toward the installation process. And for that, we’ve given a step-by-step guide below, which will give you the profound knowledge and help make your task a kid’s stuff. Without further ado, let’s get straight into it.
7 Easy Steps To Install A Subwoofer To a Factory Stereo:
No matter how difficult your DIY project is, tools can help make it a child’s play. Mentioned below are the required tools that you should get before following the process.
- A toolbox
- Subwoofer box
- RCA cables
- 50 amps inline fuse
- Speaker wires
- Wiring kit
1. Disconnect The Battery:
Nothing is more important than your safety and life. First, you have to disconnect the car’s battery to make sure it is. You will find the battery under the hood of the car. All you need is to remove the black-colored wire from the battery’s negative terminal. Once you’ve successfully separated the black cable, you’re secure to proceed with the rest of the subwoofer installation process.
3. Inspect the Car Stereo Wires:
Here comes the next step, where you have to pay attention to factory stereo cables and ports. You will need to attach your subwoofer cables to the car factory stereo. First, look for a red-colored power wire, which must be attached to the car battery. This wire will provide the subwoofer with a constant flow of energy to work smoothly.
You can run the power cable from the firewall to where the subwoofer is located. To protect the wire from any uncertain future damage, you can slip it under the car carpet and the trim panels–only slip along one side of the carpet.
The next step is to attach the fuse to the cable before connecting it with the battery’s positive terminal. You will get the fuse already installed with the kit in most cases, but it doesn’t. You have to cut the cable at some point where the other end should be easily reachable to the battery.
Now, strip the isolation of both ends, attach the fuse there and connect it to the terminal. Mounting the fuse relatively close to the battery is considered good practice since it prevents short circuits and other hazardous occurrences.
4. Check the RCA Cables and Turn-on wire:
After running the power cable to the subwoofer, you have to make the way of turn-on wire and signal cables towards the stereo. It’s the opposite of the process you’ve done previously.
You must ensure that the turn-on wire and RCA cables don’t contact the power wire while running them to the stereo. Otherwise, they will distort the sound entering the system and ruin your music listening experience.
Once you’ve done this, it’s time to attach the wires to their mean places. You have to connect the RCA cables to their respective RCA outputs on the stereo and the Turn-on wire (blue cable) to the stereo’s wire harness.
This step is only possible if you have an aftermarket stereo with preamp outputs. If you have a factory stereo, the Line Output Converter (LOC) can help get the signals from the stereo to the subwoofer. The LOC deals with high amplified signals to RCA preamp level signals.
5. Connect the ground wire:
The third primary connection is the ground wire. You need to connect this wire to the vehicle chassis or any nearby part using the bolt, which you can fasten. The ground wire must contact the naked metallic part of your vehicle. If you found some paint and any other stuff on the metallic plate, remove it using sandpaper to ensure the wire is grounded properly.
Once you’ve done this, it’s now time to install the subwoofer and set up the wiring connections.
6. Setup the wiring connections:
Here comes the step of running the test of the newly connected powered subwoofer with the car factory stereo. Check the connection of wires again to ensure everything is connected properly at its desired place.
Connect the battery’s negative terminal, i.e., reconnect the powered wire. If everything runs smoothly, you’re all set to listen to your favorite music in clear high-bass sound.
7. Get into the groove:
Get into the groove with the new sound quality of your vehicle. Turn on your favorite music, jump on your friends in the car, and enjoy the long drives to the fullest.
