I have a Denon AVR1803 Receiver and I just got a PSW110 for the holidays. I tried hooking it up through the subwoofer output, with a double RCA cable (red/white) hooked into the subwoofer through the right input (marked Right/LFE). I'm using only one of the RCA cables in the bundle for the connection. Everything is set up according to Option 1 stated in the manual, but there is still no sound coming from the sub and there is no power light on the back. There was a lit power light when it was switched on initially, but it has since gone out. I'm not sure if its a fuse, or what the problem is at all. Any help would be appreciated!

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.

Dual Voice-Coil
The unique Dual Voice-Coil design allows both left and right channel sound from just one speaker. Simply hook up both the left and the right channels to the special terminals on the speaker. Hook up one channel only, if the speaker is to be used in a conventional stereo set-up.
I found this on jamo site hope that will help you

You will not need to y connect your subwoofer, if you have only one RCA sub out on your receiver the other end of the RCA connector cable goes into the left input on most powered subs, there is no loss of signal, the option exist as some receiver do sport a double RCA sub out.

You don't name the electronics, which can be the source of the problem. See #3.

1. If you suspect the cable why don't you just swap in another RCA cable? BTW: there's no such thing as a "subwoofer" cable. Monster makes their money on those beliefs. Cables don't wear out but they can go bad if one or more conductors fails. Oxides devolp at either end which can inhibit conductivity. Remove each end and reinsert it with a twisting motion.

2. Maybe. You need to ensure the sub is defined. Run speaker level check. If no sound at the sub, prove the LFE/sub channel has output by running the RCA cable to a recorder or your TV (low volume). If there's no signal, duh, no speaker will work with it.

3. Mmm, not if it's exhibiting the same problem as the old one and the Polk 450. Have you looked at the setting of the Standby/Auto/On Switch? And the Power Mode LED's? Red is bad.

if there is multiple jacks on the sub be sure they are hooked up correctly simple mistake if not no doubtly a simple overlooked setting on your amp good luck you will get it
