how to seal holes for wires in sub boxes

I am building a sub box out of fiber glass and i havent drilled a hole or anything yet  but i plan on it to get the speaker wire to the subs. if i do drill a hole, how do i do that do i just runt the wires though and then fill the hole with glue around the wires or caulk/silicone or and ideas would be helpful. thanks

Does your box have any MDF? If so, use a terminal cup and make sure you seal the cup very well. If you don't have MDF anywhere in the box, you can seal with some bondo around the wires. I would only drill the smallest hole you can and still get the wires through. That's all I have. I'm sure when some of the FG gurus come on they'll have some other suggestions.

Dont use a terminal cup. First of all its a waste of money. Second, that plastic isnt very thick and it creates a weakpoint in the box since the plastic will flex. They are a great idea for most home sub boxes because they arent made (for the most part) to be as loud as possible.  I do agree with drilling as small as a hole as possible. To seal it up, the easiest way is to use hot glue on both the inside and outside of the box. Dont be afraid to be generous with the glue. A second way is to use caulk or liquid nails.

yes the back and bottom is all wood im just doing the front in complete fiberglass... thanks for the tips

tie a knot in the wire inside the box, apply hot glue generously to the knot, and pull firmly from the outside until the glue dries.

I used silicone to seal the hole in my box.  At home depot they have tons of different sealents that will work.  They had a couple that are desiged to stick to wood.  I got one of those, drilled a hole just big enough for the wire, then caked the silicone on.  The stuff is pretty cheap, so go ahead and use plenty of it.  I also put silicone on the inside of the box where the wire comes through before i bolted the sub up.   

i like the idea of the knot and silicone thanks alot for the help

I use silicone and resin.
