question about rear deck sub install? (long)
i am sure that everyone has seen the amazing install done by JL Audio to the b5 A4. if not check the link below. has anyone heard a setup similar to this with the subs on the rear deck? how did it sound? i would imagine it sounds great b/c the sound stage should be pretty good with the back window reflecting sound through out the car, but i also thought that subs generally sound the best when firing toward the back of the car as far as possible from the listeners ear. i am guessing that an install like this is not possible to put back to factory? would it be difficult or affect the saftey of the car if the rear deck was re-welded back inplace when car would be de-parted?
my stereo sounds great with the back seats folded down as a port but with the seats in the upright and locked possision the bass is cut almost in 1/2. i was thinking that an install like this (i know expensive and time consuming) may be a good option. i was also thinking maybe if leaving the sub in the trunk and building a new rear deck panel (not cutting the factory steel panel) but the actual rear deck's (fabricated with MDF and fiberglass) center cut out and covered with speaker grill type material would increase the bass in the car's cabin.
hopefully i don't sound crazy and my idea's description is understandable. any idea's or advice would be GREATLY appreciated.<ul><li><a href="http://www.sqplus.com/htdocs/img/bbg/bbg.htm">sickest install in A4 ever!</a></li></ul>

philly audi kid, two recommendations of places that could handle an install like that in philly
I grew up outside of philly (actually haddonfield, nj) I did some business with Goodman Radio in Bryn Mawr, they don't work with fiberglass in house but highly recommended:
The Soundsource
1702 Route 541 #9, Burlington Township, NJ 08016
PH: 609/239-1800 FAX: 609/239-0014
Sound City Odyssey, Inc.
239 S. Easton Road, Glenside, PA 19038
PH: 215/572-6419 FAX: 215/572-6425
An install like that UK install in the B5 will cost a boat load FYI. The best thing to do is to set up a small woodshop at home and learn how to work with fiberglass, mdf, & plastics. The only part of car audio that requires any experience/practice is the actual fabrication. It's not brain surgery.
The electrical component (wiring etc) is very easy to learn, hell you already have a template to work with from your first install. DIY is the only way to really get things the way you want without spending a ton and being without a car for an extended period of time. For the price of an install you can buy all of the correct tools and the materials and have money left over, and if you don't like how your system is playing and want to alter it you can do whatever you want for the cost of materials, which is near nothing.
Only after toying around with my first system did I understand all of the components of mobile audio and learn how to get my installs the way I want them. It is hard to get yourself into taking something apart that you just had done, i went about 2 years with a weak *** install in my last vehicle before I had to adapt my install for new components.
Pick up some car audio books (they cover the basics) and a good woodworking book all at amazon. to get more up to date and progressive install ideas check out some car audio mags (skip past all of the adverts) and check out some car audio forums like:
www.termpro.com
www.carsound.com
www.caraudio.com
Or this VERY informative site:
www.eatel.net/~amptech/elecdisc/caraudio.htm
there are a ton of resources for the car stereo DIYer. don't just be a consumer be an enthusiast, you do after all drive an audi.

Re: philly audi kid, two recommendations of places that could handle an install like that in philly
yea i am pretty familiar with the install process and have installed stereo's in quite a few cars, i just have never worked with fiberglass. i do have all of the bassic wood working materials because my dad used to be a carpenter, so i always have his helping hand. i actually planned on doing it myself but didn't want to get flamed because of how complicated that install looks. thanx for the help i appreciate it!
I guess you could say car audio has been my passion for about 3 years now and i would love an appreciate an install like that, especially if it was a DIY, but is it worth it to risk seriously decreasing the resale value of the car for an install like that?

my steathbox required removal of the rear deck speakers. maybe move your 6.5" to the rear doors?
it lets a very good amount of bass into the main cabin. putting some speakers in the rear doors (easy if you already had bose) will not rob you of mid-bass
i have 5.25" components in the front, 6.5" coax in the rear doors and two 8" subs in the rear that open into the cabin. I cant even imagine how loud my car would be with a w7...

i agree
i take the same approach with installs, in that i want to be able to undo what i installed in the event that I get rid of my car at some point down the line. I am not familiar with the B5 rear deck but I am sure there is a way to take it out without irreversibly altering something else in the car.
take it apart and see what you have to work with.

how about...
removing the rear deck speakers and mounting subs under the rear speaker openings? No cutting of the factory rear deck (which is not removable), and you should be plenty of sound into the cabin.

kinda...
aim the sub at the holes, yes is one way to go about it.
another thing, since you were considering cutting and building stuff, why not hang the box from the rear deck, on the bottom? Remove the rear speakers, and place one sub under each opening firing up.

A different way to do it!
<center><img src="http://pictureposter.audiworld.com/2897/dsc00808.jpg"></center><p>
I would go to Sound Waves is Prospect Park (near the Philadelphia Airport). They did my system and are great. I have been to the other shops mentioned in this post, and they do great work also, but Sound Waves has been mentioned in all of the national magazines and does competition level systems. I was really careful this time because I have had many bad installs in the past. I am not very handy, so to me, it is better to pay a professional. I have a different way to install subs. I have my ski sack removed, and the subs face forward with a false wall built facing the rear seats matching their angle. I want more bass, I can leave the seats down, or leave the pass through open, etc. Because the trunk is so well constructed, as you said, you loose a lot of bass facing the subs backwards, but facing the subs forwards reduces this a great deal.

will the rear deck be able to support that kind of weight?
how would you mount a 10" sub to a 6.5" space? i guess leave a few inches clearence? i think if i was going to do that i might as well put the subs on the rear deck. i guess mounting the sub to the inside of the trunk but attached to the rear deck with a fiberglass box wouldn't make a difference? (magnet of sub facing rear deck and front of sub angled inside of the trunk at about a 45degree angle)?????
