If you need to learn about Honda Accord Subwoofer Replacement, this article will help you to make a better decision by reading it till the end. Let’s dive in!

Swapping Factory Subwoofer In Honda Accord:

Before I go any further, I must clarify if you really can replace the existing subwoofer in Honda Accord with any aftermarket sub. The 8″ factory sub is located in the car’s rear deck, near the windows.

It’s a kind of free-air subwoofer and cannot, therefore, produce deep sound. Anyway, the swapping process requires some basic wiring knowledge and a few tools to remove the existing subwoofer and install the new one.

Before buying, it is always best to double-check that the new subwoofer is compatible with your vehicle’s electrical system. When purchasing an aftermarket subwoofer for your car, look for models with a strong bass response and good overall sound quality.

4 Essential Steps for Honda Accord Subwoofer Replacement:

To replace your Honda Accord factory subwoofer, follow the below steps carefully:

1. Choose a Compatible Subwoofer:

The already-installed factory subwoofers in Honda Accords have different specifications according to the yearly models.

So I would recommend you should choose an aftermarket subwoofer (such as a kicker sub) that compiles with your Honda Accord factory sub.

For example, if your Honda Accord has 2 Ohms single voice coil subwoofer (8″ in diameter), you should choose an aftermarket subwoofer with the same specs.

However, you can also go with the 4 Ohms free-air subwoofer setup (You should be able to convert it to 2 Ohm to match the factory amp), but make sure it supports up to 200 Watts of peak power, a frequency response of 25Hz – 250Hz, and an RMS power handling of 100 -150 Watts.

2. Remove the Old Subwoofer:

Once you choose the right subwoofer, it’s time to remove the Honda Accord factory sound system sub. Start by removing the cover panel from the rear deck of your Accord.

Remove all screws that hold the subwoofer in place and disconnect the wiring harness that connects it to the car audio system. Keep track of any screws or bolts you remove to reinstall them later correctly.

Then gently pull out the subwoofer and its mounting bracket from your Honda Accord’s rear deck lid. If you have any difficulty during this process, refer to a professional mechanic for assistance.

3. Install the New Subwoofer:

Once you remove the old one, place the new subwoofer in the exact location and connect it to the wiring harness, as the old subwoofer was wired up.

Sometimes, you must drill new holes in the subwoofer adapter plats to align correctly with the mounting holes in the rear deck. Before placing the subwoofer, use some padding between the cutout diameter and the sub.

This way, you can prevent any rattling noises from the metal deck. Now, use screws to secure it firmly, then test it to ensure everything works properly.

To get the best sound quality from your new system, be sure to adjust any additional settings on your receiver or factory amp for optimal performance.

4. Reinstall the Cover Panel:

You should test out your new subwoofer properly to ensure it gives a better sound wave. After you are satisfied with its performance, you can reinstall the cover panel again in the rear deck. You must ensure that all screws are tightened correctly.

Things to Consider Before Replacing the Sub:

Here are some essential things that you should keep in mind to prevent any damage:

• Compatibility: As mentioned above, the aftermarket subwoofer should be compatible with your Honda Accord audio system. You must check the replacement subwoofer’s power handling capabilities, impedance, and physical size.
• Warranty: Honda Accord uses Bose audio system that comes with the company warranty. You must keep in mind that making any changes to your car audio system will violate the company’s policy, resulting in a warranty drop.
• Installation: Removal and installation of the subwoofer require some expert skills. Moreover, you must have the necessary tools to complete the process successfully. Some aftermarket subwoofers may require additional wiring or modifications to your car’s audio system, which can be challenging to do on your own.
