Fiberglass Sub Box Anchoring Question

DarkStorm · #1 (**permalink**) 07-10-2009, 07:42 PM

Hey this might be a stupid question but how are you guys that make fiberglass sub enclosures that fit in the corners of the hatch stay put? I have looked over a bunch of guides and I haven't seen anyone mention anything about anchoring the enclosure? I find it hard to believe that the enclosure will stay put during hard cornering even though it is form fitted.

I plan on anchoring mine to the tailight access panel.

I'm going to use 1.5 inch bolts with lock washers and wing nuts.

the bolts will be inserted from the inside of the access covers and i'm going to silicone the bolt threads just before I tighten the wing nut.

this way if I ever decide to remove the subs I can just by new panel covers.

If anyone out there has experience that contradicts my intentions please let both of us know in the next two days, Before I myself attempt this.

Yeah, I was going to start glassing today but I wanted a second opinion before starting. Your idea seems pretty good. My idea was to remove the tie-down hoops in the hatch and get longer bolts and use though tie-down bolt holes.

it will definately move around and it gets fairly annoying. darkstorm, that sound like a good idea. its always best not to wreck stuff

I did plan on velcro as wella. however, in case of an insurance claim, I would need to prove that it was bolted to something.

really? why? in my current ek i dont even have the sub box attached. I guess its different for hatches then...

If it's bolted down then it is part of the car, and hence considered for replacement under comprehensive coverage.

thats weird. in B.C. it doesn't matter if it's bolted in or not

"Permanently Affixed" is technical writing term.

The bolts in the tail light access panel covers work great, bolt them to your enclosure then pop it in place, use a little bit of maneuvering and it will sit flush again.

do you have a pic of how you rigged it up?

I placed the fiberglass box into position where it resides in the corners, and drilled a hole through the fiberglass AND through the removable panel.

Took out both and turned the bolt through the inside of the plastic piece then when I tried to put the panel on the fiberglass the bolts would not go through withought reaming the hole a little bit first.

Once I go the plastic onto the fiberglass box with the bolt through both of them, I tightened with a lock washer and a wing nut.

I was not too worried about the air seal because i just squished the rubberized undercoating that i sprayed into the interior of the box with the lock washer.

Good luck, sorry i don't want to take it apart again, i had to finish up the install yesterday before it rained while i was out in my driveway so no pics of the process.

there is a bolt that holds the side pannel to the floor and just inside the tail light pannel there is a brace that runs top to bottom . i drilled through the pannel into the braci used nut and bolt with loc-tight.. that gives you 2 places along with velcro on the wheel well it holds tight....i also filled all the voids with expandable foam. also dynamated the crap uot of everything...bass sounds tight no raddles and sub does not move around....
