Ok, I'm going to be putting a sub in my coupes rear cubby. I have a 8" image dynamics and I want it to be a sealed enclosure - so the questions is... If you have done this, did you build a box to fit inside the cubby's space (any pix or details?) or just seal enclose cubby at the top and fill/seal the inside to get the correct interior dimensions?



Thanks Sam

Still very much prefer the powered Bazooka approach to this: you don't damage your car, you don't lose a cubby space, and the sub can easily be removed if you need every square cm available.

Haven't done it yet, but I'm planning on putting one or two subs in my Coupe. I'm pretty sure you won't want to just seal the top... the body of the car makes a bad enclosure, and I doubt you'd be able to get it 100% sealed. Better to make a fiberglass enclosure that fits in the space. Then you can always cut it out later if you want to. Some pretty good shots of a guy doing this on a Subaru can be found here.

www.klaindustries.net has a subwoofer enclosure for the cubby hole I believe. Fits an 8" speaker.

I have a KLA style panel that I made. Pix Below. The sheetmetal is lined with a high density Dynamat like substance that I found for much cheaper and some marine sound deadening mat. The aluminun angles on the inboard side hold the edge of the plywood. Flash helped with the foam weather strip around the edge to seal it up. Sounds great and I didn't even cut the carpet or pad. The flap just flops over the driver face and a grille protects the cone.

My sub came with the car so I'm not sure where it was purchased. It's looks like the KLA design.

It's a neat install with the amp/crossover fitted below.

Dave,



Yours is ported? Does that make it harder to tune? No fair having Flash help... is that your amp mounted in the cubby too? How did you attach it or does it just rest on the top. And last where did you get the Dynamat stuff - is it stuck to the sides? Ok just the usual twenty questions...



Thanks Sam

I think the KLA one is sealed, is it not? From the pics, it looks like yours is just one piece of wood that goes over the top? Wouldn't a sealed box have better quality?

The low cost Dynamat equivalent, and I mean exactly the same material, is the stuff called Polymeric Mastic sold by McMaster -Carr:Dynamat substitute

Look for part number 9709T19



My panel is just a flat piece of plywood and the remainder of the cubby is sealed as good as you can with foam and gaffers tape. It just kind of wedges into the carpet area to seat. The port is sized according to an estimate of the cubic volume and the table found in the book - "Building Speaker Systems" found at Radio Shack. One of the few good things that Radio Snack sells <img src="/forum/images/smilies/968/smile.gif" class="smilie" alt="" />



The amp is just sitting there in the hole. It is wedged in with sound deadening stuff

Did you plug the hole that is designed to drain out water? How is the sound? I know the KLA won't fit a 10", but will your design fit a 10"? I have two 10" RFs sitting in my room, collecting dust.

i am working on exactly this right now - i can't see a 10 getting in there and facing upward

The sound is decent. It is not optimized like a tuned and sealed chamber. I did not seal the drain hole. My configuration won't fit a 10" You would need to tilt a 10" or mount it proud of the surface a bit with a different panel

You are correct, the KLA unit is sealed.

FWIW, I haven't hooked up my dual JL 6W0s in my 968 yet, but they sounded incredible in my 993. Mine are sealed Fiberglass boxes with black Porsche carpeting laid over it, and are molded so that they sit at about a 45 degree angle facing towards the front seats [they lay down in the foot wells of the rear seats.



I had Hifi Buys [Tweeter] custom build and install them for me in my 993 and once I figure out my speaker options on the 968 will put them in the 968.



I will now attempt to attach this picture of them in my 993; they are only 6.5" woofers but the bass response is incredible...picks up all but the lowest of lows, and is great through the midrange.

how many people have the kla enclosure? does one sound good enough, or is it advisable to get two?



also, does anyone else have trouble (in a cab) with their rear shelf vibrating from their sub? i'm wondering if there's a way to tighten it down?



my 15" punch sounds great, but it kind of takes up the whole trunk!

the storage boxes are attached with 2 small nuts in the rear, and 2 bolts on the sides

SAM,



Your speaker want to be in a closed/sealed enclosure. You have the same one I do. Call me or email me if you lost my phone #. Mine Kicks major Butt! Waaaay loud and VERY tight not BooMy.

well, looks like i'm finally going to have to build mine - it seems the kla unit won't let me put the amp back there where i want it, especially if i only go with one, and want to put the battery back there too



i sure hope the seats don't inerfere with the sound as much as i first suspected



i'm going to try to do a test first with the bazooka and see what frequencies and levels make it through, and what don't



my guess is that i will need 2 8" drivers, in roughly .2 cubic ft sealed boxes,driven by at least 100W each, to make this work



ah yes - another project

ok - very big problem in the cab for sure - you hardtop guys have it easy for sure when it comes to subs - i have a solution, but it's not going to be what i had hoped in ease - i'll start a separate thread so as leave the hardtop thread alone

Resurecting an old thread here, but I've been looking to add a sub to my coupe and was considering the KLA enclosure. I like the idea of having it hidden away under the carpet in the cubby (even if that sacrifices a little sound quality).

I've sent a few e-mails back and forth with the KLA Industries rep but I was wondering what everyone's experince with this is here, assuming that at least a few people have installed it. I'm only looking at putting one in, does driver vs. passenger side matter? Are there any fit issues? Any concerns with it sitting back there in the cubby and causing damage to the body panels?

One thing they (KLA) mentioned was that it this was originally designed for the 944 which has the side marker light in the cubby. Since the 968's don't have this the box needs to be supported on the fender side. Has anyone found this to cause any issues?



Thanks,

Tim
