Question about Panasonic SB-WA100 Subwoofer
1. It's a passive sub. That means there is no amplifier built into the sub cabinet.2. Those are inductors. They passively filter the highs from the signal going to your sub.
3. It may work with the right adapters from Radio Shack. It would be a cheap experiment. Since the computer sub was 4 ohms and the Panasonic sub is 8 ohms, you are OK. You can always go up in impedance but be careful going lower. That's the quickest way to fry an amp.
Your Panasonic sub has 2 sets of speaker inputs and outputs. My guess is that the driver is a dual voice coil. If it says 8 ohms on the driver, then it is probably 8 ohms per coil. Wire the coils in parallel for a final load of 4 ohms and it will match your computer amp.
Finally, if that doesn't work then you can get an external amp to power the sub. Parts Express carries suitable amps from 25w to 3,000+w. Pick one that fits your budget.

Well, as I know, your Cerwin Vega subwoofer is designed for use with stereo systems. Therefore, it has only 2 channels for input, and 2 channels for output as well. However, you can try this out; the first thing I suggest is that you hook up your main front channels through the subwoofer. All you have to do is to connect the subwoofer input to the front channel output on the amp, then hook up your front speakers to the satellite output on the subwoofer. As long as you make sure that system is working on 8 ohms, I believe this can activate the subwoofer.

Does the yamaha have a subwoofer line out RCA type jack? Most receivers with 5.1 output will. Just insert a male rca to male rca patch cable from the receiver to the line in on the subwoofer,( not the speaker wire inputs) Plate on the sub may say low level input, and setup the receiver menu option for SUB? yes/ no to yes, this will direct the low frequencies to the subwoofer.
