I was just wondering if anybody has done this mod. I was looking inside the Bose tubes and all there is in there is a Sub with an amp that runs the sound through the Bose tube system.
I was wondering if anybody has replaced the OEM subs insde the tubes for aftermarket. If im not mistaken, all it would take is to replace it, seal it properly and make sure all the connections are tight properly or sealed if nescesary, Of course we would have to power it by either a small amp or regular size amp somewhere in the trunk, But at least you will be able to reuse those tubes.
I personally like the design for those subs that Bose made for RX7s, besides if i get rid of it, I will have 2 wholes in the Trunk Lid cover. I cant do aftermarket or custom installs either becuase i dont have a garage and if people see my custom system in my trunk, i can assure you, it wont be more than 2 weeks before they break into my car to steal it. so i will have to keep the trunk lid and do something to cover those wholes that the boses system has. I rather keep the Tubes and do something to make them work.
PLEASE someone give your 2 cents.

aNYBODY!?!?!?

im very curious too.
so youve taken that thing apart huh? i tried and ended up with screws i couldnt retighten. if nobodies done it, you should be the pioneer and tell the rest of us how it sounds. its a 6" right? there arent too many very strong 6" speakers out there. good luck.

SaulV

I havent taken it completly apart but enough to see the inside and to learn how the damn thing works. Its a pretty simple basic that Bose uses with all of their components, i have to admit they have gotten a whole lot better, because back then Boses sounded like ****.
Anyhow, 6" sounds like right, it should be enought fo rme though. Im not looking to make my FD SHAKE and TREMBLE with bass. Im just putting alpine all around and I need a nice clean Bass from a Sub that is clean enouh to make me enjoy music to a certain level not til I blow my ears off. Im a Professional DJ that spins at Raves and Clubs and the Last thing i need is High Volume in my car too! I like it loud but i admire Clean Sound and Accustics more than Bass and distorded sound.

i met a guy that did it with Polk 6" and it sounded better then the stock since it was able to handle more power...

But the head unit and everything else had to be changed since the OHM rating was different..........

you would need to find a driver with the same rating as the amp, or use a conversion box to match the input signal to a new amp and driver.

If you want to pull the Bose Wave Guide (or whatever it's called), you will need to buy stock non-bse carpet, or otherwise replace - and then do something with the cargo cover. either replace it with a base model part (easy) or chop off the top of the tube that stick up, and just mount them to the underside of the cargo cover - to make it look stock.

The Bose tube uses 2 6" drivers placed face to face and 1 wired w/ reverse polarity (so they are 180deg out of phase) Bose generally uses 2ohm voice coils but if you were to replace the Drivers & Amp any impedance (2, 4, 8 ohm) would be ok as long as the drivers are matched to the amp - I believe the line signal is std but not sure. but most aftermarket amps have adjustable input sensitivity so that is not much of a problem.

SaulV

mxpesce that is very important information you are giving, it impresses me but you would you please translate it to English. I have no idea of what im reading, I mean I dont know much about polarities or anything like that, im just wondering if i will be able to replace the internal sub and seal back up so i can then power it with an external amp to go with an Aftermarket Headunit and speakers.

SaulV

wait, i read it once again and i think i got it! So it means that the Bose system only holds two 6" small subs that can only hold but so much power and generally most Amp's put put more power than they will be able to hold. So you are saying that I would be able to install 2 small 6" inch subs inside the Bose Tube system and use that one reverse polarity wire that can only hold about 2 OHM and that I would have to adjust the amp to only put out that much power so i dont end up ******* them up????

Cant i just use 2 small 6" inch subs inside the Bose System and connect them diretly to the Amp and Set the AMp to kick 2 OHMs or whatever the Subs can take manually?????

maxpesce

Is short YES you can just find a pair of drivers that will fit, and wire them oppsite of each other, ie one hooked up normally w/ signal on + terminal & ground on - terminal, the other then gets signal on - terminal and ground on + terminal, so that both drivers will move in the same direction at the same time.

BATMAN

i am curious on how this turns out.............

SaulV

Im going to do it!!! Ill let you guys know ho wit turns out. I like challenges. For those interested. I think i found a couple of woofers in the market that will be able to fit perfectly.
Audiobahn AWT10

You can find these at www.ikesound.com
may be ebay or your fav car audio store.
They are hard to find in that size so im gonna try to work with these.

RX-7-Tobi

Stop!
Don't change speakers from the Bose Acoustic Wave Tube!!!
Two reasons:
The amplifier only produces its power at the 1 Ohm impedance of each driver.
Second: The enclosure is especially designed for these woofers (yes, two 6,5" in push-pull (isobaric)). Its size and the 3:1 lenght ration only works best with the OEM speakers parameter. Other speakers will sound worse.

If the performance is not enough, install a totally new subwoofer with amplifier.

I dont think youre gonna fit those 10's in the bose hose!.....Good luck!

SaulV

wILL NOT WORK, THE AMP NEEDED for that project would have to outPUT 1OHM, those amp are expensive and rare, not to mention that to find 6" Subs is a bitch. and like RX7-Tobi mentioned, It will sound like **** because of the enclosure and the way Bose Subs are designed. For the amount of money the subs and the amp cost, not to mention the custom work and the poor outcome, we are better off doing some custom work that will sound much much better and with less money

........you can at least put in new speakers for the front and door panels. But I agree, if you want it to sound really nice, go with new setup or something else. As for me, I'm spending the extra money and having Bose put in new speakers and new head units, make sure they are compatible that way everything works for sure. Actually the head unit isn't going to be Bose, I'm putting in a full DVD system! The lower slot is going to be the actual DVD player and the upper slot is going to house the fully motorized 7" touchpad screen. Very nice.

BATMAN

can someone harrass DamonB for another group buy on that enclosure he made for the FD?

RX-7-Tobi

Hi Spirit R,
same thing for the door speakers.
The amplifiers are especially desgined for low impedance speakers and the enclosure is designed for the 5,25 " drivers. Do not change anything OR CHANGE ALL.
I guess Bose did some equalizing in the amp module, at least that's the way ho they get good sound out of quite poor speakers, at least at low levels. ;-)

I would replace the Wave system sub and buy a amplifier with high-level inputs and a good subwoofer. So you can use the signal connectors of the wave tub.
But you will need an extra power cable. And short ground cable same size. The turn on signal can be taken from the wave tube connector.

Tobias

SaulV

Tobi, The problem is that You can only fit 6" Subs in there and those Subs only run at 2OHM, You will have to lower to the output to 1 OHM to make that new 6" Sub work in which case it will not only sound like **** but will also cost you money to get an amp like that

RX-7-Tobi

No,
the main problem is that each driver needs a proper designed enclosure (closed, vented, bandpass, volume size...). And any aftermarket 6" driver will not be designed for that wave tube.
Just buy a 10 or 12" woofer with a nice box and a amplifier that produces around 200 W RMS. Should have a high-power input (not only RCA) so that you can use the bose wiring for signal inputs.
