21 May Fixing The 10th Gen Civic Touring Subwoofer Rattle Issue
The 10th Gen Civic Touring sub-woofer rattle issue has been lingering around for some time now and many customers are complaining about it. The bad part is that many Honda dealers seem to be unable or unwilling to fix the issue. According to some customers Honda and their dealers are saying the issue is with the type of music and high volume that’s causing the issue. But some car owners have uploaded videos showing moderate volume/bass levels and still the rattling sound is coming from the rear. In the video below an owner shows his beautiful Aegean Blue Civic Touring having the issue.
As you can see from the comments on the above video, this is not an issue with a select few customers, it’s a widespread disease for the Touring Trim. You can also check this thread on CivicX.com to know how many owners are struck by this issue. (Scroll Down For Solutions)
Let’s talk about how you can deal with this issue? The first and foremost would be to take the car to the dealer and ask them to fix this issue. There are good dealers out there as well and I’ve heard some dealers are able to fix the subwoofer rattle. If the dealer is unable to fix the issue you can follow the following solutions step by step to fix this irritating rattle sound. However you should bear the full responsibility of any damage caused by the operation. If not confident get the help of a technical person to avoid any damages or mishandling.
#1 – Easier Method – Using Neoprene Foam & Dynamat Sound Deadener
Tools Needed For This Solution:
- Scissors to cut the foam
- Utility knife to cut the dynamat
- Putty knife
- Philips screwdriver for license plate
Step 01: First you need to insert the neoprene foam around the empty space under the rear brake-light/high mount stop-lamp (see picture below). This padding solves the issue to much extent but he problem with this method is the foam will compress with time and lose it’s place which makes this method a temporary solution.
Step 04: Now is the time to paste Dynamat adhesive sound deadener for some serious dampening under the trunk lid. Remove the cover of the trunk lid and put dynamat as show in the picture below.
Also dampen the sides of the rear-deck with dynamat sound deadener (shown below).
Look at the finished work in the below picture after pasting the sound dampener adhesive under the rear deck area.
#2 – Easiest Method – Using 1/2″ Adhesive Sorbothane Hemisphere Rubber Bumpers
This is probably the most easy workaround to improve the civic’s rattle issue. You can also use this in conjunction with the above method to get an overall improvement. Because the foam method can decay with time, this solution can be a bit sustainable as well. As you can see the picture of the adhesive bumpers they are shaped like balls and with a 30 scale on durometer hardness they can easily be fitted between the 3rd brake light/high mount stop-lamp. you can buy the product at Amazon by clicking here.
You can use 4 of these rubber bumpers placed between the rear glass and deck. Use the putty knife to push one on each bottom corner and one on each top corners of the brake light, you will have to press the deck a bit to create enough space for the rubber bumpers to slide-in. After releasing the pressure on the deck, the balls should be squeezed enough to gently withdraw the putty knife. (See pictures below for reference)
In the below picture you can see how they look from the outside after successful application.
You can also check the following demonstration video after the application, how the subwoofer rattle is gone.
