In the C5 FAQ the link is dead for the plans for building a sub box for the C5.

Does anyone have a link for that? I would like to build my own box to fit in the space at the back middle of the trunk.

Any help is appreciated!

 

If you use Baltic Birch Plywood and mostly fiberglass you can save over half the weight, what I do, what I will be offering later on for the C5 (C6 is being done now, far less weight, superb quality, what these cars deserve

Plans really not needed this way either, just do it, how I learned

I had a pdf link somewhere, but can't find it

This one opens in word:

Will this be a flush mount?
Does your design increase the air space inside the box?

 

Yes, much more air space, more depth so flush mount is easy(as long as the right sub is used of course) less weight, etc.....

Not sure when we will get to this but not to far off, month or two probably.

IF, there is a really good low weight unit available let me know, I will not do one unless there is a need

Thanks
Rick

 

I think there is a need (for me!) Looking for something to install either 2 10" JL subs or one 12".

 

I can take care of you on much more musical subs if interested, lower cost most likely as well

Rick

 

Thanks for the replys guys!

 

I just got through building a customer a stealth box out of baltic birch and you wouldn't believe the weight difference over MDF. For those looking to save on weight, this is a great alternative.

 

I believe I recommended he ask you to build it that way for him, thanks for doing so

Since there is so much more room and easy to fit I might not have my own enclosure if you are willing to make them for guys I send you, as long as it fits the IDQ10v3 at least

Not sure if we even need to use fiberglass on the C5 box which saves a ton of time and cost. A well done BB unit weight is low enough, etc...might not save any or enough to bother so it helps everyone save money and weight at the same time!

Give me a call if you wish or an email, PM, etc....

Yes, as a matter of fact you did. It helped my lungs a little, by not making all that dust that MDF creates, lol. The box turned out nicely and very lightweight. Unfortunately I forgot to get a weight, so maybe he can get one for us. It should fit the IDQ10v3 perfectly. I personally don't think the use of fiberglass would be needed on these type boxes. I also meant to get a picture, but that didn't happen either,lol.

 

I will weight it with and without the sub when it comes in the mail. Thanks again NVTHIS for building it. Also, Rick, thanks for all your help (and continued answering of my questions) as I begin the install of my complete audio overhaul in my C5.

 

Glad we can all work together on this There are tens of thousands of our great cars and many owners want upgraded audio systems. I firmly believe these cars deserve to have the lowest weight, high quality systems they can, If I can help some, others as well, more than enough to go around so we can all have some fun doing this fun business

Note: If any resonance issues you can use a drilled out(for lower weight) brace inside the box as needed. My TT car has a 2.2 cubic foot sealed enclosure, bottom is fiberglass molded to the floor that I hand hammered to a bowl shape to get the depth(steel floor of course) which stiffened it significantly thus resulting in thinner glass needed. The rest is BB, 3 different gauges, three layers right where the sub mounts so I can flush it in but beside it, over internal braces, I was able to go down to one layer due to the small unsupported surface areas. The sides, etc are all short so thin material was used there as well.

Then end result is an incredibly stiff enclosure that only weighs 20 lbs empty! This car hit 138.4 db on music for a 2 minute average with a single Arc 15 and 1kw amp beating all but one bass monster systems because they all blew up, blew fuses, speakers, caught fire, etc as only built to play a single note. My system did not clip, distort, etc just played though I have to admit it was a Bass Mechanic track

And yes, it is my TT car, it is also an audio comp car and when I get around to finishing the big turbo build it will see the track again but this time run with the system playing, I just like to do things others do not do. It weights 200 lbs less than stock with nearly a full interior, comp audio system, cage, big brakes, wheels, tires, etc........and I could put plates on it if I wanted to

Anyway, a bit off subject but wanted to let you know my dedication to low weight, high performance audio


Have a great day!

I had an '04 Z06. With the fixed roof coupe, you have a great opportunity. I put three 10's in a rectangular box at the front of the cargo bay. Very little side room was left, just enough to run wiring and push/pull fans for ventilation. It separated the cabin from the trunk area. This gave me unbelievable bass by reducing the cabin volume, and it reduced road noise from the rear tire wells.

Also, light weight mdf is available, but I think it flexes a tad more compared to regular mdf. Any sub should have internal bracing anyway, so i suspect light weight mdf is fine. Do not use nails only, especially if you are going to run sealed and high power. Use rabbets on the panels and screws (if using mdf, then use mdf-specific screws). Baltic birch is good stuff, but make sure it is the 13 ply, not the 7 ply.

If you don't want that setup and are going with two subs, then I recommend one sub in each corner. That is called corner loading and it is sonically advantageous and more efficient.

 

I just weighed the birch sub-box without the sub in it. It is 11 1/2 lbs.

 

Not bad at all

I have not used MDF for over 10 years now, the only thing it is good for is large trim panels in 1/4" as not as prone to warp as plywood.

BUT, if you need that then use Alumalite instead, super stiff, will not warp, incredibly low in weight

 

I know this is an older thread but maybe someone can answer this.
Will the Alpine SWR-12D4 Type-R 12" fit in this box?
Thanks in advance
-Taylor

 

Nope, not the 12". The 10" would be close, but should definitely fit if you add a spacer ring on top.

Any shallow mount 12" sub should fit fine, but deep ones like that won't.

 

Thank you for the quick reply, so with the 10 inch and a spacer ring I should be good?

 

Most likely, yes. Fold up a cardboard box using the plans to see how much room there is for the sloped portion, then compare it to the sub specs. Just be sure to make up for the thickness of the wood compared to the cardboard.
