CA's Most Hated
I bought a brand new JL12W7 off eBay and a ported box with a 1.5" front baffle, built exact to JL specs, from the same guy. This guy has pretty good feedback (3000+ positive) so I figured his boxes must be alright. After I installed the sub and started playing it I immediatly noticed a leak in the port (where the wood from the port meets the front. I sealed up the holes with a some Shoe Goop (only thing I had around and figured it would work as good as anything). Today I took out the speaker wire terminal and sealed all that up with Shoe Goop. I think there are some more leaks because this sub should be louder than it is now. It is being powered by a 500/1 amp and I am soon getting a 1000/1 to replace that. Whats a good way to check if the box is leaking? Thanks!
