Fiberglass build (updated pg3)

[3stagevtec]

My 1st time building one of these. Enclosure is for my pops Mazda B2500 pickup. The vehicle has limited space so I chose to locate the enclosure in the foot area between the rear seats.

When completed, 3 people should still be able to sit in the rear with the enclosure in place... hopefully...

1st up, the sub.. Sundown E8..






Epic suspension!


The rear cupholder had to go..






Plastic bag and masking tape galore! The rear bench seat was moved forward about ~0.75" to make the mold. That way when completed, the gap will prevent the seat from squeaking against the box.

5 layers of resin and fiberglass..




After an overnight dry..


The sides were marked and cut according to the shape required. The box is being made in such a way that rear passengers can rest their legs comfortable against it. Well, that's the intention anyway..




The right way to cut the resin.. i.e. the personal protection.


Test fiting


with seat in place.. Notice the small gap between the enclosure and seat..

The baffle


The slanted edge allows the factory glove box to open without restriction.. I ran out of hot glue, hence the duct tape..


A cloth was pulled over the sides and soaked in resin.


Simple masking tape was use to keep it in place..


It was then hung upside down so the wet resin soaked cloth would 'balloon' out a bit and form a nice smooth shape.




So far, the sides are coming out as intended. I doubt it would be intrusive to any rear passengers..


as soon as the cloth dries firm, I will put down a few layers of fiberglass for strength and see how much volume i end up with..

Sundown recommends a 0.6cu.ft enclosure tuned 30Hz for the E8.. Hopefully, i'll be close to that.. If not, a 0.28cu.ft sealed (Qtc - 0.7) is recommended..

[pimptacular]

nice build so far man..
how much space are you expecting?

[3stagevtec]

I estimated it to be around 0.5cu.ft but somehow it 'looks' bigger than that.. Once it comes near the 0.6cu.ft mark, i will use an external 2.5" PVC port and tune it accordingly.

My dad is not much of an SQ person, he and his brothers had a DJ back in their day, so he tends to prefer loud rather than quality.. ported would definitely be more to his liking..

His front stage uses the factory door speakers (I really like the tone / midbass you get from them) and a pair of PA tweets. I can't remember the brand, but they are run off a '3 way' passive crossover (LP / HP and rear fill) I got from SR..

so this is how u spent d 3days when tuner break down ...lol


i guess whoever is unlucky to sit in d middle will have to have a leg on either side of it


looking good so far ...

[SmokeyGTi]

nice! like i better contract you to do my van too!

If it's one thing, the stock speakers in the b2500 give you impressive midbass, especially with a decent quality head unit.

[southside connections]

very nice work so far there

keep it up!!

[fuzz_174]

good work yo

[DYNAMIX SOUND SYSTEM]

NICE BUILD BRO.. KEEP IT UP.

[theblitz]

I like the PPE
When I'm sanding fg I use a full disposable cover-all and a full face mask like yours though... I don't play with that sh!t at all

Great job so far!

[masterofmindzchris]

kool....post a vid with a few tunes when completed...

[X_Factor]

if its firing upwards, is it too late to countersink the sub so there is less chance of contact with a foot?

[theblitz]

^^^ that's a helluvalot of counter-sinking you talking about there if you look at the sub again lol

[3stagevtec]

if its firing upwards, is it too late to countersink the sub so there is less chance of contact with a foot?

The baffle is really small, so it would be difficult.. I will look into countersinking the sub though once it's possible and there is enough internal volume..

Will post a vid when completed..

[X_Factor]

yeah, or a decent grill to prevent the sub from being damaged with someone's foot and it can happen very easy

im not sure how/if it will work for ur application...but what about a 3/4 ring over the existing baffle on the top..and fiber and filler the edge of the ring and taper it to the existing baffle
it will also give it a nice custom look rather than the flat top

[kurpal_v2]

Where u bought gluesticks?

[Sully]

Do you have the specs on this sub? I can't find any info on the website.

Its been replaced with the new SA-8.

[carfreak1024]

those SA-8 subs are supposedly some of the baddest 8" around. If you like #s i saw somewhere that with one SA-8 sundownz hit 150db or 151db or some, with 1 8".

it was on an SAW3500D though.

Good work. Looking forward to the finished project.

[Anton]

Looking good. Those E8 gave a nice flattish response when i modeled them on WinIsd even in the ported enclosure.

[jeff]

looks great! i've tried this before and the tactile response in your seat is going to be like a hardcore sundown massage!

[carfreak1024]

so what is the power for this build going to be, let me guess an sae1000d or some.

Pioneer Premier Class A 4CH amplifier.. 2CHs bridged to run the sub, the other 2CHs run the front stage and rear fill through a passive crossover..

75Wrms per channel, which is plenty!

[nello-sello]

nice work man

[Chiney]

lookin bess!!

[Morpheus]

Nice work
