If you have a hole in your car subwoofer, you can easily repair it at home. To do this, you will need to access the damage, unscrew the car subwoofer, clean the area around the hole, and use RTV silicone to fix the hole. It is recommended to wear gloves during the procedure. To repair damaged speaker foam or rubber rings, you can use a blade knife, scalpel, or pair of scissors.
As a glue, you can use Parts Express Speaker Repair Glue for excellent sealing. To apply the RTV silicone, cut off the end of a cotton swab to transform it into an RTV applicator. Dip the swab into the RTV silicone and use it to apply the RTV silicone to the bottom of the subwoofer tear. You don't need a lot of RTV silicone on both sides of the rubber cover, just enough to form a very thin layer. Repairing a hole in a car subwoofer is not difficult and can be done with minimal tools and materials.
With proper preparation and care, you can easily repair your car subwoofer and get it back in working order.
