Changing the inpout voltage of inside bose Acoustimass module

Confirm there is power in the wall socket and that the mains cable of the Acoustimass Module is OK,then check if the Boselink audio cable is inserted firmly into the zone1 output of the Media Center and the input of the Acoustimass Module.Turn the Acoustimass Module upside down and power the system,if led indicator blinks orange,the Acoustimass Module is faulty but if it blinks an intermittent but regular green light,the fault could be from the audio cable or Media Center.Only a qualified Bose Technician can handle this kind of fault

The output voltage on the secondary appears to be tapped at 22 and 16 VAC.

i just bought companion 5 1 month ago and am facing this same problem from 1st week. its an embarrasment. i had given it to the service center and they could not detect the problem. so i did my own research and found that if i kept a fan blowing on the rear vents of the acoustimass module the problem does not occur.you also please check it. i have again given the acoustimass module to the service center and told them this lets see what they do???

YOU'LL GET IT ON EBAY

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.

it need it own sub out speaicl done so bye bose steyem crossovers wont work right in your set up nee dto upgrade the sub try mtx

try taking ones apart that have the rumbling and see if theres anything loose inside

I have the same problem too, I have replaced the fuse that blow inside, but did not work it just blow again and again call bose and they told me that may be the amplifier that when off.
