Is it possible to hook the infinity bu-1 subwoofer to a home theater system where the subwoofer output is straight power say it"s like 25 watts coming out of that one channel and before the original subwoofer use to be a 6inch unpowered sub, i"m just wondering what the ohms are on the bu-1 because your not suppose to hook anything to the system below 8 ohm as far as the sub goes and the amp on the bu-1 saids it"s 4 ohm or no more than 4ohm minimum, i also took out the sub and looked on the back of the magnet and i didn"t see anything about ohm"s on that, i was just wondering would the subwoofer by itself be the same ohm as the amp its running off of, i"m thinking the subwoofer has to be 6-8 ohm for a house system, i know car audio is 4-ohm mostly and your not suppose to hook car speakers to 8 ohm house stereos

The connections on the control module all depends on what outputs are available on the receiver or whatever audio component you have.
Probably the most straight forward hook up is to connect the receiver's speaker (R &L) outputs to the speaker Inputs of the module, however you may have potential outputs on your receiver that could used. What I suggest is for you to provide the information on the receiver with make and exact model number so the receiver outputs can be matched to the model. http://ec1.images-amazon.com/media/i3d/01/A/man-migrate/MANUAL000030686.pdf

The link is for a system module manual, and it describes all the possible hook ups based on the outputs of the receiver. If you can provide the additional information on the receiver, I will try to asssit you further.

Hi,
here it is some tech info ..it is a fair price for 2.hand unit...
as ebay has the similar prices..it seems to be a good deal...

Take care and please Remember to rate/vote and give me 4 Thumbs Up

Active or passive subs (size is irrelevant)? Do you have the manual(s)? It might talk about that. If active subs, get an RCA splitter cable and share the subwoofer output.

hook them up and play something,, the speaker should bounce "out" on bass sounds, if it pulls "in" switch the wires

Pin assignment is as follows (not sure of levels required- preamplification / attenuation may be necessary:
1: Control 0/5V.
2: Unused
3: Unused
4. Center speaker in
5. Ground
6. Ground
7. Subwoofer in
8. Ground
9. Unused
10. Ground
11. Left Front speaker in
12. Right Front speaker in
13. Ground
14. Right surround (rear) in
15. Left surround (rear) in

if the impedance of the new speaker matches the impedance of the old one then i dont see why it wont work

check the fuse in the sub.

Try hooking up a different signal input to your powered sub, another stereo or even a dvd players audio output to the sub will work for a test. Just make sure the subs gain is down before starting. If it still not producing sound, the subwoofers amplifier is bad. I hope this helps.

When the wires touched, the output transistors overloaded before the fuse had a chance to blow. The outputs need to be changed. It is possible that the driver stage for the final outputs is bad also, but there is no way to know that without removing the bad outputs. Figure on $25-$45 in parts for this repair.

In general, there are two ways to hook up your sub-woofer. First using the high level outputs from your receiver ( speaker output from the front R & L speaker terminals ) run a set of wires from the outputs to the speaker inputs on the sub-woofer, you do this in concert with the speaker wires going to the front R & L speakers which you then attach to the R & L speaker outputs on the sub woofer amp. Note that the sub woofer doesn't power your front speakers, the connections from the sub amp are just a pass through connection where the signal needed by the sub is parasitically taken from the inputs.
Second is via a low level output from your receiver / amp to the low level input on your sub amp. This is normally done via a RCA type of patch cable and connected to the sub woofer RCA jack on the rear of the source receiver or amp, Next run the patch cord to the sub amp an into the RCA jack input. IF you have a right and left input, use the Right input.
