How To Repair Surrond To Cone

Introduction

I realized — a fiddling too late — that a couple of retaining clips were rubbing against the pinnacle of the subwoofer/enclosure in my car. One clip was (thankfully) scratching the subwoofer enclosure carpet, simply the other one had poked a hole on the subwoofer's prophylactic surroundings.

I removed the retaining clips then at that place would be no problems in the futurity, but the damage had already been done. So I figured what the heck — might too make a guide!

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.

Assess the impairment. Depending on the severity of the cutting, you may demand some other scaffolding fabric (bated from RTV silicone) to enclose the pigsty.
This is especially true if a chunk of the safe material is completely missing from the rubber environs.
In this case, all we need to do is cover up the tear with RTV silicone in guild to make the subwoofer most as good equally new — functionally, at to the lowest degree.

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

Unscrew the eight #2 Phillips screws using either a screwdriver or cordless commuter.
Exist conscientious if you utilise a cordless driver for either screwing or unscrewing — you don't want to strip the screws or the enclosure'due south holes. You also don't desire to accidentally create another pigsty in the condom surround with either tool.

Utilize a flat pry tool (such equally a flat-blade screwdriver) to prop up an border of the subwoofer.
In my case, I but used the Phillips #2 screwdriver I had on-hand.
Slide your fingers underneath the sub so that you get a practiced grip on its border.
Carefully lift the subwoofer out of the enclosure, minding whatsoever wires that may be tethering the sub to the enclosure.

Use a make clean, lint-complimentary cloth to wipe away any clay/grease/grime that would otherwise tarnish the bail between the rubber and RTV silicone.
Inspect the underside of the tear and also gently make clean it with a material, if needed.

Time to get dirty. Put on your favorite brand of nitrile or latex gloves.
Put a dab of RTV silicone on a disposable plate, or some other clean, non-essential surface.

Cut the terminate off a cotton swab in order to transform information technology into an RTV applicator.
Alternatively you tin try removing all of the cotton wool from the swab, but y'all certainly do not want any cotton wool fibers to remain on the swab.
Dip the swab into the RTV silicone, and use information technology to utilize the RTV silicone to the underside of the subwoofer tear.
You do non need a huge corporeality of RTV silicone on either side of the rubber surround — merely enough to class a very thin layer.

With the underside coated, put a dab of RTV silicone onto your gloved finger.
Gently spread the RTV silicone across the front of the torn subwoofer surround.
Over again, yous don't need gobs of RTV silicone in social club to make a stiff bail — but enough to form a thin layer.

Perform this activeness at your ain gamble -- you may inadvertently open up the hole again, depending on its size.
Push down a couple of times on the centre of the subwoofer to ensure that the RTV silicone doesn't accidentally impede the movement of the sub.

Subsequently you're done applying the RTV silicone and testing the subwoofer's circuit, shine a strong flashlight through the now-covered pigsty, and ensure that no light bleeds through.
Ensure the sub wires are nonetheless connected properly, and reinstall the subwoofer back into the enclosure.
