I am sure someone has hooked up a self-powered subwoofer. Can you please tell me "how" you did that and what "hardware" like Y connectors are necessary. I currently have a NAD C325BEE integrated amp and a PSB Image 6 subwoofer. Thanks.

Following that recommendation, lower part of frequency spectrum will be reproduced by sub, and upper part (above sub's crossover point) by your main speakers. Problem is, the overall quality of the sound will degrade because of additional components in the chain. I wouldn't use that at all if your system performs 2-channel duty, i.e. not dedicated HT.Better option is probably to run main speakers full-range, and augment low end with sub. With your NAD, you'll need pair of RCA Y-adapters (1 male to 1 male-1 female, or 1 male to 2 female plus additional male-male connector or short cable) to connect as follows:
- single male end into pre-out
- split male end (or female + add. connector) into amp-in
- split female end + cable into sub's line in.
Hooking the sub up to your pre out and still giving your main speakers the full range signal will be a nightmare to setup, if not impossible.You absolutley need to have your main speakers crossed over in some way. The sub's crossover, on it's own, no matter how well designed, is not going to match your main speaker's falloff curve.
So... either use the crossover built in the sub to connect your mains to (recommended), or have a receiver with one built in that has an LFE out (your NAD, of course, does not have that)... and the only other way is to connect the sub to pre-out number two, and place a passive crossover between pre-1 and the amp in and then match the crossover points that way. If you want to go the route of external passive crossover, let me know and I can post a link to the place that sells them.
Connect the amplifier Left/Right OUT terminals to the subwoofer IN Left/Right terminals. Connect Left & Right speakers to the subwoofer OUT Left/Right terminals. No special adaptors required, just proper wire termination to suit terminals.
