Stock Subwoofer Specs

[Burtonnboarda]

Hey, Ive searched all over these and other forums trying to find out some sizing and specs for the stock subwoofer. Because I want more bass but dont have money at the moment to drop into a full system that is going to come later and was wondering if the stock sub could be replaced with a shallow mount sub and just call it a day.

anyone every try it or know sizing and specs?

I have the non Bose system and I know mine is a 10" but i dont know any wattage numbers

[DUDEFROMRI]

Non bose is NOT a 10inch, Possibly an 8, but def not a 10"

[n7plus1]

per my '03's audi symphony owners manual, i can at least tell you it has a 70 watt subwoofer....i wish it had a size listed, just go lay in the trunk and measure it.

[B6Lovin]

im fairly sure it's an 8

[JerseyShoreA4]

I have audi symphony and I think there is a total of 10 speakers. Components in the 4 doors=8 and 2 subs. I think there is actually two 8s but I think one is a passive diaphram and not a complete speaker.. Forget how those actually work. I haven't crawled into the trunk to check it out tho so I could be completely full of shit.

^^^oh sweet, a passive radiator. Good idea to effectively "port" such a tiny box

to the OP...trying to find just the right driver would be more difficult than just making a small sealed 8" sub box and using a small amp to power it. Any crappy two channel could be bridged to do the job if you're going for all out cheap. I'm just about to slap a $50 Resonant Engineering 8" sub in my Avant for some more bass and am using a small $100 Rockford Fosgate Class-D amp. I'm putting it in a fiberglass box for aesthetics but I'm sure a little MDF box would do just fine in your application.

Now, it would be fun to see someone power the OEM sub outside of the car off of something to see what kind of excursion you can get :evil laugh:

^^Good link on the passive radiator. I'm almost possitive that is the setup used in our rear decks.

Nope, there is just one sub back there. The 10th speaker is the center on the dash.

Yeah definitely only one back there.

If i get a extra sub and amp or lets just say i have them around. LOL :)

where can i get a remote (rem) wire connection. I know i can get one from the trunk somewere and i dont have to run the wire from the front Deck to the amp. Any clues?

[A4TL]

they sell a line level device that detects signal and engages a relay to remote power the amp. i did this on the bmw.

line lever converters to the two rear speakers; remote converter to the line level; fused power to the battery in the trunk. jl10w1 in port tuned box. no wires to front sounded GREAT with the harmon kardon as "extra" bass. not ghetto-blasting levels but enough to really enjoy the harmon kardon dsp/sound system which smokes audi bose up and down the street all day long.

What year is your car? Bose? You can grab it at the stock amp in the passenger's side of the trunk. I know behind the radio there is the harness with ~20 pins (not all filled) and it's the thick white wire on there.

stock sub is like a 9 or 8.9inch sub. i replaced mine with a 10. it was a PITA!!!

And how's it sound?

Bose and non bose have the same size speakers.

I have 2002 and yes its BOSE. also the guy above said something about putting a 10" sub in the stock location. Can i put my 10" MTX sub in the stock location and hook it up to the stock amp?

Check the Stereo Info link in my sig, there is a pinout of the bose amp for your car. I wouldn't put your MTX sub in there unless it's made for an IB setup. Also the Bose amp probably doesn't have enough power for it.

If you guys are looking to have a sub out of the way, PM A4Moda. His shop makes enclosures that fit on the side of the trunk. I have one waiting to go into my car and I can't wait to hear how it sounds.

there is a white wire coming off the factory unit. it is the remote wire for the amp in the rear of the car.

Thanks also

make sure you verify the wire once you power up the radio

lol for sure

Would this work in our rear deck ---> 8" Shallow Sub

[Capt. Obvious]

It will work, but you still need a box. They aren't made to be a free-air sub.

[JerseyShoreA4]

I wonder if with some reinforcing if I can get my 10 inch solobaric into the stock location.

[ungucpho]

no. the stock subwoofer is housed on the rear deck, downfiring into the trunk. you can do it if you mount underneath the rear deck. if you wanted to fit a sub in the stock location, it would have to be a free air sub with a depth of 2-3 inches.

marine subwoofer my man.
infinite baffle.

and i think pioneers new shallow subs are free-air capable.

or you do a shallow sub that require little airspace. and do a shallow enclosure that is mounted to the deck it self.

"Marine" doesn't automatically mean infinite baffle, it usually just means it's able to withstand water splashes and high humidity situations.

The specs for the sub says it needs .8 cubic foot box, which is a bit smaller than infinity.

[gotdubd]

most marine subs also have the options of being free air.

[ungucpho]

take apart the rear deck and you'll see what i'm talking about

the subwoofer is downfires into the trunk, between the rear deck and the cover for the rear deck, there is only a few inches that will between the those 2 pieces. find a 8" sub with a few inches of mounting depth, maybe it'll fit

if you mount the enclosure to the bottom of the rear deck you're better off putting an enclosure inside the the corner of the trunk since the box would stick out like a sore thumb

I used to have two 12s mounted to the rear deck, remember that? If any one is thinking about doing it...don't just have A4moda make you a box for the side of the trunk.

And how's it sound?

I'll do a write up soon. I am using a Kicker CompVT 10" with a Cadence FX+1500 amp.

the setup is good, for what i was striving for. I wanted more hit than stock, but not too much. although this sub if it was in a box would hit a lot harder, which i wish it did.

the kicker i'm using fits PERFECTLY with my configuration. Only downside is that with the factory headunit, and having the signal tapped off the rear speakers the sound processing isn't up to snuff with aftermarket units.

basically it sounds like the stock sub with a little more power. wish it was more fine tuneable but i'm limited because i am using the factory head unit. if using an aftermarket head unit the sub would sound a lot cleaner, since aftermarket head units have low pass filtering and a user configurable Equalizer. Right now some songs have NO BASS and other songs are overworking the sub. Then again a few songs, anything that Dr Dre has produced sound GREAT!. Wish i could run an aftermarket headunit that fit like stock.


ohh btw. most higher quality subs can be run infinate baffle (free air). they will NOT hit as hard as in an enclosure but it'll work and sound fine. It won't be super high quality or hit as hard as it should, but it doesn't sound like shit one bit. its all in your settings on your amp, and if possible settings within your head unit. I am essentially running my sub infinate baffle since its located at the factory location on the rear deck. I could seal up the rear trunk, but i don't really think it will make a huge difference with the factory head unit powering everything.
