I'm looking to put in a sub at the factory location. I have audio20 so there is no sub in there at the time.

I know the stock sub is 8" but I'm looking to put in something larger.

To anyone that has removed the rear deck, how much room is in there? IE if I take a saw to the metal panel and attach the sub to a piece of MDF what is the max size I can fit? 12" maybe larger?

PS I dont want a sub enclosure because I dont have folding seats and I wont sacrifice the room. Besides I can throw enough power into an IB sub to get the job done.

ROLLNNN

I dont have any answers to your questions but I'm interested to see how this turns out. I was looking into doing an IB sub before, but people were saying that it wont sound that great, so i just scrapped the idea... Please keep us posted.

Thanks

I have wanted to do this for a long time too so BUMP for the topic!!

I did some research and talked to some people and the pioneer IB Flat is what i came up with too

as far as I remember looking at the underside of the rear deck of my car (Harman system) there isnt a whole ton of room, but I have never taken off the deck. Id be worried about the vibes from a huge sub ruining your rear sun shade motor and also giving your rear passengers headaches.

Bad news guys. I just took some measurements, Looks like we can only fit 8"s at most 3 of them which isnt that bad. But honestly is it even worth having an 8" sub. (can you even consider it a sub when it can only hit 50hz at lowest)

With some additional modding a 10" might be possible (if its skinny), 2 of them might make it alittle better.

I am sad

Sad day for w203 owners. I'd consider putting a box in the trunk, but stabilizing it would be an issue.

Fit one or multiple JL Audio 8 inch subs. They are excellent. Vastly better than most.

ps - you will have to amplify them properly.

I've made my choice,

It hits down to 5hz, for an 8" I'm sold. It wont work infinite baffle but I'm sure I can rig up a 0.5 cu ft fiberglass box for the rear deck.

My last set of subs were 2 12" Orion's in a 4th order bandpass box, amplification I got.

Whatever floats your boat. Just don't end up with mono tone, one note booming bass. It sucks & 5Hz means nothing in the hostile audio environment of a car. You have to decide whether you want decent, fairly accurate sound or a Ghetto Blaster. Ghetto blaster is easy - decent sound is a lot more difficult.

JL Audio fall into the highly civilised category.

JL falls into the over priced category.
ID subs are used by audiophiles the wold over, as the #1 bang for your buck woofer.

JL makes good equiptment, there will be no debating that, but I'm not a rapper trying to show off the JL logo. In its defense the JL can use 50% more power but for the money I can run 2 ID8's hit lower, harder, and with an extra 2db from running the additional sub. (any more then that is madness on stock everything else)

You need not worry about a boomy system, you see I'll be running a sealed box at .5cu ft. Click that more specifications button on the ID page and behold how flat that Freq response is. Boomy systems generally go with 6th order band pass boxes, or very poorly tuned ported boxes.

When it comes to high end subs - apart from proprietary designs from the likes of B&W, Vienna Acoustics, Martin Logan etc. I think there is little doubt that the decent subwoofer market is ruled by JL Audio, Paradigm & Velodyne.

JL Audio subs are not expensive when one considers their capability & nothing matches them in car audio.

I will stick with the proven brands thanks - being an Audio Research & Magneplanar lover. I've been down this road many times. Most car audio sucks & more crap is spoken in this area than anywhere else in the audio hobby.

ps. I don't give a rats *** about anechoic or other measurements. I care about sound as I hear it. X Overs are a science all of their own with given drivers. I use Bryston 10B Sub X Overs in my bi amped system & even they are not perfect in my super Maggie surround set up. (MG 3.6's all round)

Good luck with your car sound.

Any pics of your system in your W203 Glyn? I am starting to research adding a sub to my 203 soon.

Anyone bolt a proper sub enclosure to the rear deck so the woofer fires through the stock location?

Glyn M Ruck

John,
I have the stock system in my 203 (Audio 10 + 6 disc stacker). I gave up on car audio a long while back. I have two large systems at home. One in my little home theatre. That's where I get my high-end audio kicks these days. I help friends with audio in their cars but consider it a hostile environment for sound.

A decent enclosure with a JL sub will work well under the parcel shelf - See JL sale from

JL Audio 8W7 FTW!!!! Thats all that I have and it gives me the bass I need.

johnand

You and me both., I gave up on car audio years ago as well, but have a very satisfying home theater. Just want a little more low end in my w203, so I may just do a JL 8W7 in a box attached to the parcel shelf. Thanks for the website
