Answer 1

You have to tell your receiver 2 things so it will send lots of sound to the sub:

- Tell it that all your speakers are SMALL

- Tell it that you have a subwoofer attached

Also - if the sub has a crossover k**b - turn it to max. Otherwise the sub may ignore some of the sounds the receiver sends.

Get a copy of Avia, Digital Video Essentials or Sound and Vision setup dvd. These have test tones which you can use to make the sub make noise.
