Subwoofer enclosures

TheRandom1 · Post by **TheRandom1** » Thu Feb 18, 2010 2:08 pm

I'm kind of tired of having a huge box in my trunk and was hoping to change it out for something different that will free up some space.

I know the SRT's have the sub enclosure on the drivers side, but has anybody made one for the passenger side? That they're offering for sale at a decent price, I mean... someone's custom build doesn't help me unless it's for sale as I don't really want to mess with FG work.

Ideally, I'd like to put my 2 12" Kicker CVR's in the wheel wells like that and still have a trunk to put more than a case of pepsi in...

I may be interested also depending on price. Although my cvr's are in a box that is still small enough to let me fit 3!! 24's packs in my trunk.

Yeah... not so much here! lol

They pretty much go from the edge of the back seat to the edge of the trunk lid.

Mine is sloped on front, plus it's not nearly as deep. And just to let you know, having the amp ontop is going to rattle it apart. But not many other places to put it lol.

It was like that when I bought it.

I'd rather mount it to the seat, or under the deck or something... but no reason to do that until I get a new box, as there are already holes in this one.

don't expect anything cheaply. all the corner boxes i have built have had at least $75-100 in materials alone, and that does not include labor. if you wanted them painted add another few hours of labor plus associated costs. unless you are willing to do the labor there is nothing cheap about fiberglass. even if you do fine one you have to be sure that the airspace is correct for the sub you are installing. that being said i do plan on building one for my type-x this spring.

It doesn't have to be fiberglass, I would just prefer one that's formed to fit in there and not a wood one I could build.

nineball · Post by **nineball** » Thu Feb 18, 2010 4:16 pm

fiberglass is your only option then. no one makes pre-fab corner boxes for neons. the only pre-fab option you have is the qlogic one that sits in the spare wheel well.

the only way to make a plastic injection version would be to make one out of fg, then remove it and use as a base to make a mold, then inject the plastic. to do that you are talking thousands of dollars.

TheRandom1 · Post by **TheRandom1** » Thu Feb 18, 2010 4:17 pm

Actually, I wonder...

Could I do the injection molded deal if I had a spare trunk? Drill a hole in the fender for the vacuum, and do it that way?

nineball · Post by **nineball** » Thu Feb 18, 2010 4:38 pm

anything is possible but you need more than just a spare trunk. doing it your way would give you the form of the trunk wall but you would not have a front half. you would still have to build one and then somehow seal the two halves with enough strength to take the pressure created by the moving subwoofer.

building an enclosure out of fg is really not hard. you just need a little practice on something smaller until you get the basics down. check out www.fiberglassforums.com and you can see pics of the build process of thousands of boxes.

I never said it was difficult, just that I don't want to mess with it.

Just a thought, might/might not work, get a can or two of that expanding foam, a small/medium trash bag, and some sturdy cardboard. Put the bag in the recess that you want the sub in. You may need to tape it in place, to hold the shape.

Duct tape the cardboard over the recess, in whatever shape, clearance you want/need. Have enough of the bag opening sticking out to fill it with the expanding foam.

Let it cure. I would go for the shipping stuff. I think Great Stuff takes too long.

Remove your mold, send to your favorite person with a vacuum forming table. Just make sure they form it with the outside edge up, so you have the flat surface to mount the sub to.

It may need to be reinforced, but if the foam will hold to the vacuum process, it would make a slick enclosure, that would fit like a glove.

^interesting idea

Post by **occasional demons** » Thu Feb 18, 2010 9:23 pm

Only if that packing foam doesn't get crushed by the vacuum.

It holds up very well shipping heavy motors, etc., but IDK how all the little air spaces will react to negative pressure.

hmmm... good idea...

You're an ingenuitive mofo. Slick idea.

LOL I want some room 2. Never will happen for me I have 2 12s & a 15 in my trunk on a 2,000 watt rms mono amp.

TheRandom1 · Post by **TheRandom1** » Tue Mar 09, 2010 12:57 pm

Yup, that would be a bit more difficult to do...

I once had two tens and two fifteens. Lowrider in the back lol.

Do something like i did but relocate the sub. Build the box below. And raise the floor a little. I did it with an inverted cvr 15 still with a lot of room. I have pics on here. Just to hard for me to find on my phone.

Nevermind found the thread:

Looks pretty good, but would 2 12" subs fit in the wheel well? I thought they'd be too close together.

Mr Josh Zombie · Post by **Mr Josh Zombie** » Wed Mar 17, 2010 9:05 am

just go with a smaller set up. i single 12" in a properly tuned box will give you more than enough bass.

TheRandom1 · Post by **TheRandom1** » Wed Mar 17, 2010 9:06 am

I don't know how to figure any of that stuff though. I just plug in, tune the stereo and go.

Not a bad idea on going with one sub though...

my single alpine type R in my cobalt was MORE than what i ever needed. i only ever maxed it out to be irritating to those around me

TheRandom1 · Post by **TheRandom1** » Wed Mar 17, 2010 9:10 am

I need to check the specs on my amp to see what it'll do bridged to a single channel. If it'll even do that.

Paralyzer · Post by **Paralyzer** » Thu Mar 18, 2010 11:53 pm

Get the Program bassbox pro. It is a car audio builder's best friend. You put in the specs of your sub, your amp, how much power, ported or sealed, and basic design. It will tell you how much airspace you have and everything. Great software.

Just looked at it, and I'm not worried about airspace just yet. I'm more worried about finding out whether my amp can bridge down to 1 channel (it can, about 600x1) and whether my sub can handle it if it does (it can't, RMS is 400)

So it seems that idea is out the window for now. Unless I sell my current stuff and buy new, which I'd rather not do really.
