Lookin pretty good, some filler and a lot of sanding and you should be in REALLY good shape. Whats the volume and tuning? and what subs are you putting in there? I'm guessing its going in a chevy cause of the bowtie right above the port.

port looks small?

it does.

What's going in it?

The glass looks a little thin also.

this was kinda a low budget build. i had about 560$ to do everything. ive ordered 4 ma audio ma12d4's. 400 rms 800 peak. still need to buy an amp. The box is going in a chevy blazer. (Fits Snug, very snug)lol. i dont really know much about port sizes and all that stuff. im more into the electrical side of it. i read on another thread that a basic rule of thumb is to push on the fiberglass, wherever it bends of flexes at all, it needs more glass. still need to add more.

Push on it? With a properly built box you should be able to stand and jump on it.

QFE

A box that isn't properly tuned is USELESS

Might as well close off the port and make it sealed.

I dont know much about the glassing, but that port looks REALLY small compared to the airspace in the box. I would say seal it off and stuff the box with some polyfill.

 

[carfreak5312 10+ year member]

ill just close it off prolly. (port). keep in mind that all i did was glass it

 

[carfreak5312 10+ year member]

i can make the port to the right size, but like i said before, im more into the electrical aspect of the whole deal. can someone help me with the tuning. isn't it hard to do with all of the curves.

You'll need to find the (relatively) exact airspace, which shouldn't be TOO awful hard. Then you can calculate the port tuning and adjust from there.

I'd say with all the effort and cost put into that box, you really REALLY should make the effort to tune it properly, or you will likely be very disappointed with the sound at the end of the day. If it's just about looks, well, then seal it up and call it good, but if you want it to SOUND decent, get to work and determine the actual airspace inside you're working with, then we can help you with the port tuning.

You need more FG!!!It should be about 3/8 to 1/2in thick if not more.Maybe try a layer of kitty hair.
