Fiberglass box for 12" sub

[ocuriel]

I have a 01 Acura MDX. I'm in the process of building a 12" sub box for a 12" OZ audio 12.2 matrix sub. I pulled the factory 10" sub & used the opening to get the most air space possible. Here are a few pics. I'm hopping to get more this weekend.

This is the mold already made & cut to size - I then sanded the corners smooth which the picture doesn't show. The speaker ring was made for a flush mount installation.

These pictures show the fleece already stretched & glassed. It was a pain to get the fleece wrinkles out. I added 3 layers of glass matt on the inside of the fleece vs. the outside. This makes it much easier to get a smoother finish. Next step is to get rid of the excess fleece & then start adding bondo to the outside. Not the best or most detailed pictures, but I hope you enjoy :) .

Here the box is coeated with 3m premium body filler. This stuff sands off real nice.

Here the box has been sanded smooth, primered & then I added putty to fill in the very small holes & indentations. I used bondo uv drying putty, which f'n sucked. It was a pain to sand down & I eventually took it all off & had to primer again.

Unfortunately I over estimated the box size. This box is too small for thje oz, so I will be switching over to a IDQ.

covered the box in vinyl this weekend.

I own a 2004 Honda Pilot so I feel you pain. Are you still going to be able to get the factory grill and panel over the sub? BTW, looks REALLY good...

[ocuriel]

Thanks. The sub box will extend out of the hole making the grille useless. Will probably use the cloth on the grille to wrap around a custom grille, making the sub somewhat stealth.

Pilot owner here too (well, the wife's piolt) Post more pics, I'm interested in the turn out.

Sorry but I laughed out loud on after reading that... Man, do I feel your pain. But it's all learning process...
It is really looking good. I am anxious to see how it will fit into the MDX though... Thanks and please keep me/us updated.

[ocuriel]

It really got to me. It's a very nasty product. Putty is suppose to sand very easily, & this was lke trying to sand plastic off. I took a step back instead of forward when i put this crap on.

Added a picture

[chad]

Wow after seeing it inside the SUV I found out that it's WAY different than the '06!

BUT it looks great! I'm anxious to hear your comments.

[edwelly]

ocuriel - anyway you can post a bigger picture of it mounted in the MDX?
Very interested in hearing how this sounds and loks. Thanks!!!

[ocuriel]

I can't comment on the sound. Box is too small for the OZ audio sub. I can tell you this though, that sub sounds so clean & effortless when tested free air. I'll have more pics this weekend.

I agree totally. IMO...the worst product they make.

When are you getting the IDQ 10"?
BTW, GREAT job on the vinyl...

[ocuriel]

I already have it. Waiting on t-nuts & a grill to come in so I can install it properly. I did test it out in this box. match made in heaven if you ask me.

[alphakenny1]

looks good man. i'm thinking of making a fiberglass box for diyma :D.

looking good

[ocuriel]

Thanks. I used this grill

[vwtoby]

Ahh..is it SEM sprayed or did you wrap it?

what adhesive are you using to lay your vinyl?

[ocuriel]

It's wrapped. Used cloth from old speaker grill.

As far as the adhesive, I used 3m spray. I think it was the 77 or 80. Works okay.

What size enclosure is that, i'm trying to get a good idea of what a 1cf enclosure would look like, as measureing size of a non rectangle with wierd shapes looks to be the biggest problem assocaited with FG. I know the packing peanuts method, as well as the water method, but i'm just not safe figuring this out with water.........any suggestions?

[ocuriel]

I'm estimated close to .7-.8 before sub displacement. I honestly considered 3rd row seating clearance before box size. I figured I can then fine tune the sound using pollyfill.

Packing peanuts would give you a pretty accurate box size. Do the measuring before you glass the fleece in case you need to make any adjusments.

[demon2091tb]

Yea that may work, but i'd think if i had my speaker baffle and all up and then wrapped it in fleece like you said before classing the fleece then it may work but just not sure how close i could get it, and yea i you could use polyfill to fine tune it before any EQ.

[chad]

As opposed to packing peanuts one can use the small foam beads like in cheapo Bean Bag chairs. This would give you a more accurate representation because of the more uniform shape and less air void between the "peanuts"

When measuring for my wierdo ports I used water, it was not that messy and spot on accurate.

Looks really nice. I like how it matches the rest of the cargo area.

[edwelly]

ocuriel - damn fine job my friend. Very impressed. So, how does it sound???

[ocuriel]

Not sure yet. I stuffed it with a 1lb of polyfill at 1st and It didn't really sound right. I took half out and have since sold my radio so I didn't get a chance to hear it with 1/2 lb of polyfill.

Dying to place my order for a new radio, but bills come 1st :(

[ocuriel]

I just snapped some pictures for the sale section and figured I should post the amps installed.

....hmmm why not invert the woofer allow for more aire space?;)

[02bluesuperroo]

Yum, sweet amps!

[unpredictableacts]

What will ahppen to that poor oz matrix woofeR? I may be interested? would 400-500 watts do it a bit of justice?

[ocuriel]

....hmmm why not invert the woofer allow for more aire space?;)

That sub is long gone. I have a infinity perfect 12.1 in it now.

Sorry, That sub is long gone. I added to an old thread. My buddy has that sub now. He has an alpine pdx 600 watt amp on it and it slams clean and tight. I think 400-500 watts is perfect for it. It's a great sub. Too bad my box couldn't acomidate it.

Where in the Chicago area do you live?
