Question about Bose 3·2·1 II System
By "other receiver" i mean use it as a subwoofer for another system example: a sony home theater system...
someone gave me just the subwoofer and nothing else...so i removed the back cover and i can see the cables that send the speakers signal but i want to figure out wich one of those cables are the ones that receives the input signal so i can use it with my existing system...
i know that the bose systems have propietary connectors so you dont have to remind me that...in fact i would like to "invent" with it so please if someone can help me i would be veeeeeeryyyy grateful...thanks and greetings from Puerto Rico...
I received a broken Bose acoustimass subwoofer... and by broken I mean the built in amp part didn't work. I don't have the module to control it either... and I wasn't given the unusual power cord so I couldn't even test it.
This is made in 1991, so I suspect it might be a series 1. It's in a white rectangular wooden box with a white plastic amp controller section up the top. It might be similar to the one you have.
Anyway, there was a little flap at the very top in the center and I removed a screw, then gently levered off the volume/bass/tone dials off with a flat screwdriver. I was then able to lever the entire top plastic outer box. I ended up just removing all of the circuit boards, heat-sinks etc. I won't go into the details but its a simple matter of undoing whatever screws you find and unclipping any joining cables between boards.
The power supply is mounted in a recessed plastic box that kind of sits inside the top of the box... I removed the power supply from the plastic box and set it aside.
Eventually I had the entire top section clear with a stereo cable coming out of the woofer. I snipped off the white connector at the end of the cable (that used to plug into one of the boards) and hung it out the top. I then replaced the recessed plastic box (that had the power supply) so that the top of the box was sealed again. I put the heat-sink over that just because it looked nicer (there are no electronics for it to absorb heat from). I made sure everything they were screwed down properly (so no undue vibration).
Basically I have now taken out all the electronic components leaving the driver in a sealed box, with the stereo cable still hanging out. I stripped some plastic off the ends of the stereo cable to expose the wires and attached a long stereo lead to the wires. I put the other end of the lead into the speaker out of my home stereo amplifier.
I started playing some music and it actually had quite a lot of bass. It wasn't too great at mid-range or high-end but it's not really supposed to as it's meant to be part of a 2.1/5.1/7.1 system. It will be good as part of any surround sound system.
