ok, so i started my wall build today, the back wall, and floor are braced with 4 2x4's glued & screwed, its going to have a double baffle, and tuned to approx 38hz

the entire inside will be fiberglassed for extra strength, along with internal bracing, every panel with open space behind, below or above it will be filled with expanding foam, i dont think this box is going to budge much....hopefuly...this is my first attempt at a wall, any constructive critisism is VERY welcome, if your just going to be negitive.....get the **** out of my thread....

and no, all of the rear interior has been stripped, the big odd shaped panels are being glassed shut against sheet metal sanded w/ 40 grit making that small piece of sheet metal a part of the eclosure, the only parts that will be like this are the small wheel well areas that are twice as thick as the rest of the car. so it will be plenty stout enough, all the other spots bridged with fiberglass will be 4-5 layers thick (mostly all very small areas)

metal is just a no no for box's. If you look at all walls they use a large box and than everything is braced inside. Than the panel is placed on the front and sealed from the back. With your design your going to have leaks you can use how much glass you want it still won't work.

id say build the area where you need to gap as an amp rach put a 2x4 all way around and put a new back of box against that then you can use other side of 2x4 as frame to either mount amps to to mdf to flus mount the amp/amps that is my opion and seal the crap out of it

what does it matter? fiberglass can be just as strong if not stronger, plaus way lighter than mdf.....

problem with fiberglass it does crack over long times of abuse unless you coat if with gelcoat and duraglass

MisterGrubbs
06-27-2008, 12:02 AM
Good luck on your first build.

I agree with what has been said, those gaps are simply too big. How hard, in all honesty, would it have been for you to A) use whole pieces of MDF instead of piecing it together and B) take an extra 20 minutes to measure and cut a piece of MDF to place where those gaps are? I'm not the best carpenter in the world, but man come on!

I'm not hatin, I've done some dumb things in my time, but you need to make those gaps smaller, and then glass them. You will regret leaving that large of a gap in there. There is a VERY good chance you wont seal them, but if you are as talented as you say, you should be able to.

Where are your measurements for area coming from? Do you have the room for 8 12's ported? It honestly does look like it at this moment...

Good luck man, I can only wish you the best. If you were closer, I'd lend a helping hand.

GohillaAudio
06-27-2008, 12:04 AM
untrue.......it doesnt just "crack" it will become brittle over a LONG time......but i change my systems so much......it doesnt matter, duraglass is just a filler to smooth out fiberglass to finish it, and gelcoat is mainly used for mold layups...has nothing to do with structure, unless its in a marine application, then gelcoat acts as a waterproofer...of sorts

MisterGrubbs
06-27-2008, 12:06 AM
What it comes down to. Listen to suggestions and be open minded.

Continue with your build, and prove us wrong.

It's not the 100% best way to do it, nor is it "our" way of doing it, but as long as it does it's job and holds up to your standards, go for it. Just keep us updated.

I'm not going to say it couldnt work. Hell if you can build a whole huge enclosure from fiberglass, why couldnt you make a few corners with it...? But in this case, I dont think it was needed.

the subs are hifonics hfid412's they were sponsored
the amps are ultra linear ul1602's they were also sponsored

so its a pretty cheap setup....but 6 of them hit a 147.5 legal on the tl in a sealed box in my trunk (no rear seat) so it will be reasonably loud

I have always screwed mine in, but I am sure others have just glued them in. Your box is going to flex, so maybe some other people could help with that.

Should have just made the biggest box you could fit in that area using striaght and properly glued seams. That little bit of area you are gaining by using weird angles and glass you will lose 10 fold in integrity. You just build the biggest box you can, brace it foam it, and then make a face to seal up the front of the box into a wall.
