Basic guidelines to follow to install a powerful subwoofer to the factory stereo system:

Power subwoofers have all of the vital equipment such as an amplifier, enclosure, etc. that a subwoofer system requires to have. So, let me introduce you to the guidelines to install a powerful subwoofer.

  • Look for a suitable place to mount the subwoofer

Generally, subwoofers associated with amplifiers produce heat, and that is why it requires enough ventilation opportunities. So, find the right place where you can efficiently mount the sub. There should be easy access to the fact.

  • Disconnect the battery properly

For instance, you must dissociate the negative battery terminal for your safety. You must save yourself from unwanted shock, and that’s why adopting this step.

  • Running the power wire rightfully

In the next step, transfer the cable to the powered subwoofer from the battery after running the wire effectively. Then crumple the terminal ring to one aside and connect the fuse holder on the other end accurately. Make sure you are putting the fuse adjacent to the battery. Never leave the lead unprotected.

  • Drive the turn-on wire and function the signal cables nicely

Once you have finished running the wire, the next step is to lead the live wire and RCA signal cables properly. It is necessary to create a connection to the factory stereo.

Make sure you are plugging the cable into the right outputs on the stereo configuration. Running them from the reverse side of the car is necessary because it prevents electric noise access. Otherwise, it is going to upset the music quality. On the factory stereo system, the signal will respond differently.

  • Add the ground wire effectively

At this stage, you will get a positive and negative terminal of the speaker joining with the ground wire. Find a bolt where you can fix a ground cable. It should be in touch with the bare metal of the car. You should ensure the best connection.

  • Create a powerful connection

After finishing the crucial steps rightfully, you must raise the powered subwoofer and make a secure connection. The wires should not be bent and maximize the possibilities for making gentle curves on it. This process limits the chances of creating unwanted wear and tearing.

Now, you must join the negative battery terminal that you disconnected before. Test it whether the subwoofer turns on or not while you start the car.


At the final point, play some of your favourite music after installation of the powered car subwoofer to the factory stereo. If it functions properly, then you have done a successful job.
