SOURCE: subwoofer

Most AV receivers do not have a built in amplifier block to drive a subwoofer, and merely provide the subwoofer output channel at line voltage. Thus, a powered subwoofer is required. Does the subwoofer require mains power? From your description, I'm guessing it doesn't. If not, it does not have a buit in amplifier, you will need to purchase a monoblock amplifier, which is just a mono amplifier with a volume control, no tone controls or anything else. Make sure that the amplifier power rating is as close as possible to the subwoofer power rating, as it is quite possible to blow a speaker by using an amplifier whose power output is too low, by overdriving the amplifier , and putting DC through the voice coil when the amplifier clips. If it does require mains power, it will have an amplifier built in, but does not have line level inputs.

SOURCE: subwoofer installation

no jack =no sub audio signal so you would have to get some kind of summing filter. this would sum (mix) the two signals together and extract the sub audio from both channels in order to drive the powered sub woofer you have. could be expensive dont know.

SOURCE: AR1 Subwoofer Keeps Blowing the 5 Amp Fuse

Well, so far so good. I reinstalled the newly repaired amp and fired it up and so far, so good. Ran it through about an hour of fairly intense break-in tracks and then ran it through about 2 dozen power up and down cycles to try to get it to fail (better now than a month from now and have to fight them on backing it up).

SOURCE: I have a celestion s80

Dont remember which cap it is , but its 47 uf 35v, on one corner of the board. You can use a slightly bigger value and slightly higher voltage if thats all you can find. Check the two caps next to the voltage regulators, these go as well problem sorted!!!!

Rw12fuse blown klipsch subwoofer. The new fuse blows instantly. What else can I try?


If it's continually blowing fuses you have an internal circuit problem, best to take it in for repair at that point.

I have the SB-HW950 subwoofer and teh SC-PT950 speakers and I just purchased a Denon Receiver to replace my DVD/ receiver player. So now I have SC-PT950 speakers playing through the Denon but for some...


Yes, the old Panasonic SC-PT950 did drive the subwoofer by its own amp, such as it was.

It's never a good idea to adapt prescribed connectors to bare speaker wire or vice versa.

Speaker Level and Line Level signals are worlds apart and equipment damage may result. Your Denon (model unknown) probably requires a POWERED SUBWOOFER, to which it would provide Line Level LFE from its Pre Out.

Read the manual where it doesn't say to convert a speaker wire to RCA.

Mission m-cube sub fuse keeps blowing


If you have replaced with the correct rating and the fuse blows off then you will need to check for higher current drain in the sub woofer or the network. After replacing the fuse load up the subwoofer slowly, reduce the bass and as you increase check at the point the fuse blows off. Now we need to analyse if the rating of the amplifier you are using is rated for the subwoofer. If your subwoofer has a higher rating you can increase the rating by about 25% and check again. Some amplifiers give a very higher voltage on full bass which could result in such a condition. Moderate this and check again. If the fuse stays Ok you can continue with this new rating.Otherwise the output of the amp at higher volume needs a confirmation. Hope this helps. Good day

Subwoofer blows internal 1.25A fuse when plugged in.


Any fuse blowing is caused by an overload in either the power section or the amp part. Look arond for burnt or damaged parts first. It could be caused by a shorted transistor, but your best bet is to follow the circuit from the fuse on the PC board.

Fuse blows


Both 3 or 4 amp slow blow fuses are suitable replacements for the 3.125 amp subwoofer fuse.

It could be that the subwoofer is blowing the fuse because the one you installed was not slow blow.

But, more likely is the subwoofer has a short in the power supply which is causing the fuse to blow.
