In my enclosure when the guy made it, they put a hole for the wires and just put the wires in a put a little tack to seal it up. How much of an effect would this have all together and should I take further precautions to fix this? When I was using the box it didn't sound bad personally, but thats completely subjective.

As long as it is sealed it won't hurt anything.

It's pretty common for people to do this in high power set ups. Terminal cups have been known to melt. It's possible that the builder was just trying to cut down on the resistance from the amp to the sub. I thinks it is still very professional and if it is sealed up properly its legit

Alright, well thats a relief.
