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...


In general higher speaker impedance is safer than lower impedance for the amp. Don't expect anything impressive re: audio output from a passive (unpowered) sub if your HTS says it pushes only 25 watts. Without frequency bandwidth and distortion noted the spec is virtually useless as a comparison.

The BU-1 is a powered sub that accepts either RCA Line Level or HIGH LEVEL amplifier power. If you use the latter, impedance is a non-issue because the input feeds the BU-1's internal amp, not the speaker directly. You should be okay.

Perhaps if we knew some specifics about the HTS we could do more than guess.

WHAT FUSE IS USED IN THIS SUB


The fuse is external, mounted on the back. I think it also holds a spare fuse. Rating is marked next to the fuse holder.

Infinity BU-150 has deep hum soon as plugged in


most likely it's your signal cable. You might first try plugging the sub into the same power outlet as the preamplifier, if it is not already.

Good luck,
