I would like to change the 110 volt input transformer in my Acoustimass subwoofer to a 220 volt transformer. The current number on the unit is 194459. What is the model number for the 220 volt unit?

Has it ever worked?

Try this - connect one pair of its speaker wires at a time and test it. Watch the polarity.

• Make sure all cube speaker arrays are connected to the proper terminals according to their
position in your room.
• Check to be sure all wires are connected to your surround receiver with the proper polarity
(+ to + and – to – wires). Incorrect wiring can result in a total loss of module output.
• Correct any wiring problems before you plug in your receiver and turn it on.

SOURCE: Hi. I got a Bose Acoustimass

Do you have any plan to use the Bose Acoustimass 20 sub/amp in it original form?
Please double check the pins count.
Popular Bose unit has 8,9 or 13 pins.

A Bose third party vendor does sell a direct cable from the Bose Acoustimass 20 to two RCA and 1/8" stereo jack.

I'm sure you can find other cable vendor at a lower price.

I do not recommend you to open the Bose Acoustimass 20 and get the two set of wires out of the box.
It may cause damage to the casing.

On the DIN plug.
With notch / dimple facing the ground.
From let to right
1 = RED negative
2 = White negative
3 = RED positive
4 = White positive
5 center = un-use.

Please use an ohm meter to verify the resistance between1 to 4 and 2 to 4 before you start hooking up to the amp.

Please keep my posted on the project via email.
