Ok...I just weighed my box. I didn't want to mess with taking out the sub which weighs about 6 pounds or so. So....the unloaded box weighs about 28 pounds shipped from 97220.

Still thinking about this. Surely someone has built a system that uses the trunk as the sealed chamber and ports into the cabin.

I have a box that does JUST this for my E34...there is a guy building them for people on bf.c and r3v.

For an E28 box, Luke charges $250, you have to have at least 4 orders in to make it worth his while and they wouldn't be ready 'til well into summer. I'm not hating on the guy at all; he makes a sweet box, but I think this is a better solution to my needs. Plus, I like supporting a local business!

Jeff, thanks again!

Thanks dood! I appreciate the business. Did you reglue that center dust cap?? That's what was rattling. Mine was loose, glued it back in place, no rattles. Clean bass.

Yeah I was thinking that I would match up the carpet here locally, the exposed section.you could wrap the box though.

I haven't messed with it much. I have some other rattles that I need to locate and tweak with the amp settings. New amp may be coming soon if I can't get it to sound better. Project for the weekend!

You can get it cheaper on Ebay. My box is not 100% sealed but it actually gives a pretty strong bass. I've had my sons seating in the back and had no complaints of anything hitting their behinds!

Is there a DIY on how to make a box like this somewhere on this forum?

Better yet, is there a DIY on how to construct a fiberglass box for under the seat?

check out a place like www.diymobileaudio.com for fiberglass tutorials.
Laying glass is laying glass, doesnt matter if its an e28 or Chebby cavalier. Its the techniques that matter.

You will need a baffle ring, there is an eBay guy that sells them cheap.

what i dont like on the "sub under rear seat is that the box is way tooo small and wont reproduce great sound in that little ass box. and you will be missing out on alot of quality bass. the OP's Idea is awesome on the other hand

Incorrect, and I seriously doubt you've even heard a decent shallow mount sub let alone installed one. You won't win any volume competitions, but man do these things hit all of the notes.

I would take a shallow mount sub that can fit underneath my rear seat and even allow someone to sit on it, than take up a third of my trunk space for an obnoxiously large sub that is not necessary for the speakers that are contained in the average person's car. It's music, not a "who can wake the neighbors up" contest.

It's audio snobbery!

Oh! Oh! Pick me!

Do those run directly off 12v? I have to use a power inverter.

These stealth sub boxes, well I took the back panel off of mine and used the fabric to cover the box itself. I use the top of the box to mount a board that has the crossovers, amps and fan. The area next to the sub box has the 'stiffening' cap and will hold a quart of oil on one side and the jumper cables in a US Mint dime bag.

I don't have pics of the set up now but have one of what it was before I covered the box with the stuff from the back panel. Having this extra space available, although the sub is not stealth is the way to go in my opinion.

The sub box, ported or not, needs to be made for the speaker(s) that will be used with it. My sub box has a pair of 10s in separate 1 cu ft sealed compartments because that gives my speakers the best overall sound quality. If you need to verify that, they are Goldsound woofers designed for acoustic suspension in a 1 cu ft box.

I need to get the new amp installed so I can drive the system a bit more.

For twice my price.

So I guess it is true: imitation is the most sincere form of flattery...so thanks! Seriously, I really do appreciate it.

I will have a few E34s at 5er West, mine included. I would be honored for you to stop by, take a listen. Mine will not have much of a system, the goal is to have the entire system able to be replicated for $500, including one of my boxes.

Make sure you hear the E28 I did for James Crivellone at 5er, too. The box for that install is of course far more complex: the face is stepped to fit that metal brace across the floor of the E28, the woofer is properly recessed, it is ported into the cabin, and the output of the box from both ports and the woofer is sealed into the cabin, so there are no rattles anywhere.

It also has a full car PC install, and active tri-amped 5.1 true surround sound, with a full active tri-amped center channel!

When you hear the detail and clarity of the bass in that car, you will understand why I do things the way I do.

As far as what you are doing, I really am happy for you. I hope you stay busy, and I hope you learn more tricks along the way. In fact, let me offer my help! If you get stuck on something, just hit me up on Facebook at German Audio Specialties, or on (one of) my site(s), www.germanaudiospecialties.com.

(Yes, that too is still under construction, but I am up to my eyeballs in work. I can't even begin to keep up.)

The more people you introduce to the idea of a custom fit box, the more customers I will have available, right? Those who don't want to pay for the level of engineering and construction of mine would do well to go to you rather than Car Toys, right?

I have basically no intention of ever producing an E28 box. I have shipped well over 200 E30 and E34 boxes now, apparently they are kind of legendary. People come to me when they want the absolute best in fitment and sound quality.

I do my best to please them, believe me.

When you hear one and see how they fit, you will understand all the extra work that go into mine. The goal for me is to offer the best SQ, the most logical use of space and the best value on the market. I hope you are as proud of your work as I am of mine.

Here is an E30 trunk with a E3010 box, a 5 channel PPI amp and a simple "pretty panel"



Here is a box I custom built for a guy in LA. He will be using the Image Dynamics IDMax 12" woofer, this box is vehicle and woofer specific. He will be handling the cosmetic part of things, but it will be at Bimmerfest this weekend:



All of the odd shapes on the front panel are to force the box to seal into the cabin, again, this sounds much better and eliminates 99% of all rattles. The ports will be through the rear deck, and again, sealed into the cabin. The crappy carpet job is only a gasket and is not visible when installed, but getting the carpet and the foam gasket to fit the car perfectly was more important.



Quick note: the woofer shown is NOT the one this box is intended for, but only to show how the box looks with the woofer installed.



Yes, the face of the woofer is vertical. The mouting depth on this beast of a woofer is so deep that you cannot angle it with the seat back, to make it fit into the ski pass location you would have to cut a hole in the floor of the trunk!

The porting is dual 4", over twice the port area typically used in a 12" box. This means far far more engineering and far more work, but all for a great cause: the most stunning bass at BimmerFest.

Here is a simple idea of how the porting works. Of course, I have a standard method of sealing the ports into the rear deck and into the box, but I won't bore you guys with those details.

Owned.

Uhhhh....who are you? I only know of you from an offhand comment last week by a friend who says you build boxes, charge accordingly, and have a reputation as an ass. Building subwoofer enclosures to fit in a particular spot and look as though they are not there is nothing new. Imitate you? Puuuhleeeze! I have been wanting to do this before ever hearing of you.

Your work is obviously good and you obviously do it for a living. I do not. You have put plenty of time into planning, tuning, fitment, etc. as you should. I build commission furniture and other fine woodowork. I simply take the skills I have and apply them to building a quality box that does what I want it to and offer it at a reasonable price. I am not interested in an installation that fits like a glove. I am not interested in the time involved. For what I have made, it sounds fine to me and I doubt hearing a perfectly tuned system will change my ways. I am not a car audiophile and do not need the perfectly tuned system. Those folks can go to you.

So, thank you for your good wishes and your look what I did style sharing of your work. It truly is well planned and thought out. I'm sure it sounds great, it's just not what I need.

Use the search button, I've built 12" sealed shallow sub boxes for under rear seat and they sound really good but I hate building them . . . fiberglass sucks. You don't need to cut holes from your trunk for the sound to come through for a sub in the trunk. It's not very hard to diy for the shallow sub under rear seat, lay down some tape then fiberglass and use mdf for a flat top. Make sure you use good respirator, resin and activator are neurotoxins.

Talk about hijacking a thread

Let me take this opportunity to let you know how great at what I do as well. Being a record producer I hope nobody steals my idea to also produce music, 'cause I invented the concept. The only difference between us is my web site has more than a splash page. but then, you don't need any more than that since you are so good at what you do.

I agree with you on the fact its just music. Thats why i have only one sub. Thats all i need; im not like people around me who have 2 15“s and think its hot....your just ketting people know you have something worth steeling.

I have never heard the true sound of a shallow mount. So ik guess my opinion is a bit bias.

You stole the idea from ME. Just look at the date I joined mye28. It will be clear that I am the true original.
