More power Can you add an amp or increase the power output of this receiver? I have the bose acoustimass 10 w/out the powered subwoofer. (Big Mistake!!) This unit does not drive the speakers. I do not want to add a powered subwoofer. (limited space) Is there a mod for the receiver? Thanks

Acoustimass speakers need to be driven by a Hi-Fi amp/receiver or AV receiver. So the thing that's driving them needs to be an amplifier.

Unless your radio is also an amplifier then the radio and the Bose speakers are not directly compatible. There's no suitable output on the radio that generates the correct signal in sufficient power.

your acoustimas requires you to connect all speakers outputs to it first then to the speakers.

Hi, ok the Bose Acoustimass III system consists of two small cube speakers and one subwoofer unit called the Acoustimass bass module. If the subwoofer stops working, three points can be the cause of the failure. The Bose Acoustimass III is a passive system, meaning the speakers do not power themselves, but instead are connected to a receiver or amplifier. Thus, the amplifier, the speaker between the amplifier and the subwoofer, or the subwoofer itself could be the issue.

Things You'll Need:

* Amplifier
* Speaker cable
* Extra subwoofer


Instructions


Disconnect the speaker cable from the back of the Bose Accoustimass bass module and connect it to a subwoofer that is known to be working. If the subwoofer works, the bass module needs to be replaced.


Disconnect the speaker cable from the back of the receiver or amplifier you are using and from the back of the subwoofer in Step 1.


Connect a speaker cable that is known to be working between the back of the receiver or amplifier and the back of the Accoustimass module. If the module starts working, then the cable was the issue.


Disconnect the speaker cable from Step 3 from the back of the amplifier or receiver, then connect the cable to the subwoofer port on the back of an amplifier or receiver that is known to be working. If the subwoofer works, the receiver was the issue. If the subwoofer still does not work, verify that the speaker cable is in the subwoofer port of the receiver/amplifier and that the cable is connected securely to the subwoofer.



If you think you did the connection properly,Fine... If not you can use the manual from the below link and know how to connect it properly..

Have a nice day..

The entire speaker system is passive. That is, it requires amplification for each channel.

From the manual: "Compatible with A/V receivers rated from 10 to 200 watts per front channel and 10 to 100 watts per rear channel; rated from 4 to 8 ohms".

If you have it literally conencted the way you say not much good will happen.

The speaker OUTPUTs for the Yamaha feed the INPUTS on the Acoustimass Module then the satellites branch out of the Acoustimass Module's OUTPUTs.

Acoustimass module
Bose® recommends putting your Acoustimass module at the same end of the room as the
television monitor. To prevent interference, keep the module at least 2 feet (.6 m) from the
television.
• You may hide the Acoustimass module behind or under furniture, but do not block the
opening. Be sure there is at least 2 inches (5 cm) between the opening and any surface.
• If the opening faces the wall it increases the bass; if it faces away it decreases the bass.
For the most bass response, place the opening 2 to 3 inches (5 to 8 cm) from a wall or
corner.
• Stand the Acoustimass module vertically or horizontally (Figure 6). To stand it on the
cable connection end, remove the cover by gently pulling it away

Move the sub closer to a wall or corner to increase the bass.

This is a SYSTEM and as such is not designed to be pieced out or separated. I don't recommend that you try it that way. I doubt it will improve the sound.

The entire 5.1 amplification system, in the Bose Lifestyle 35, is actually part of the Bose Acoustimass (subwoofer) module. The RJ-45 (network type) connector passes a low-voltage signal from the console to the Acoustimass module. If you were to hack the connection, and plug the speaker outputs of a 5.1 receiver to the RJ-45 socket on the Acoustimass module, you would blow the amplifier.

If you are really itching to replace the Bose Lifestyle 35 console with a regular 5.1 receiver, I strongly suggest you sell your Bose system, and purchase a Bose speaker system, such as the Acoustimass 10 Home Theater Speaker System, which is made for use with a standard 5.1 surround sound receiver.

Well, first of all this speaker system is designed to give you a subwoofer where you do not have a sub-woofer output on your receiver/amp. However, that is not the case with the Onkyo. The way I would set it up (only because of the speakers you have) according to the Acoustimass Manual. You take the left and Right "Speaker" outputs to the Left and Right input on the Acoustimass and the speakers crossover does the rest. The Onkyo is designed to have a powered subwoofer so in this format you would just tell the receiver to turn off the sub channel which would tell the Onkyo to send the low end to LR. That should do it.

Usually the LFE out is only a line out and is not amplified in any way, so first of all is your subwoofer self amplified or not? Cause if not, the LFE output won't be of much use to you. So if it's not self amplified you need an new amplifier to put between the receiver and the subwoofer. Any amp that supports RCA line-in input will do. Even a car stereo amplifier will work provided you can get a 12volt power supply to run it in the house. If the subwoofer is self amplified though, then all you need is to make an adapter cause none are readily available in stores to go from a RCA connector to 2 wires. You can buy a virgin RCA connector that you can wire yourself at The Source, Circuit City, or any electronics store you have locally, or if you have an old RCA to RCA wire you don't need anymore, you can just cut it in half, strip the 2 wires and you got you adapter right there.

Hope this may help but you will disappointed. as heard from some pro, your amp will blow up the bose cube if direct connected to them, they are powering down your output to fit their tiny speaker. My understanding was you have to hook up everything to the bose module. They don't like to play with others.

Ok, have you tryed to unplug all of the wires from the sub, including the power wire from the wall. Install of the speaker wires to the sub, and plug back in the sub. Also what are the numbers on the speakers and the sub.
