Hole in Subs Surround?

[HiAmplidude 10+ year member]

So pretty much any clear, strong adhesive. If silicone do i need to get the caulk type stuff or the straight silicone? Also this is a rubber surround so would rubber cement hold up? I was also hearing about gorilla glue and CA glue. Which would be best for a screwdriver size hole in my subs rubber surround

Personally, I wouldn't use anything that dries hard, or very thin. You're putting it on an extremely flexible surface that gets a ton of flex, stretch, and roll -- constantly, not to mention pressure. I would use the most flexible, stretchy, yet durable and strong-bonding adhesive possible. Take the woof out, flip it upside-down and apply it to the inner-side of the surround roll to avoid making it look like crap. A good recommendation is clear silicone adhesive or straight silicone (like the stuff you'd caulk your house windows with). Don't put in too much (or too little) -- oh.... and, be sure you clean the surface thoroughly befor applying it. Use Windex or something to take off any dust and possible grease from the area for a better bond with the adhesive.
