Introduction

I realized — a little too late — that a couple of retaining clips were rubbing against the top of the subwoofer/enclosure in my car. One clip was (thankfully) scratching the subwoofer enclosure carpet, but the other one had poked a hole on the subwoofer's rubber surround.

Step 1 Subwoofer Rubber Surround Repair

Assess the damage. Depending on the severity of the cut, you may need some other scaffolding material (aside from RTV silicone) to enclose the hole.

Step 2

Unscrew the eight #2 Phillips screws using either a screwdriver or cordless driver.

Step 3

Use a flat pry tool (such as a flat-blade screwdriver) to prop up an edge of the subwoofer.

Step 4

Use a clean, lint-free cloth to wipe away any dirt/grease/grime that would otherwise tarnish the bond between the rubber and RTV silicone.

Step 5

Time to get dirty. Put on your favorite brand of nitrile or latex gloves.
