    That sub has it's own built in amplifier. The amp you have will only send a signal to the sub, but the sub will use no power from it. It is it's own independant sub-system.

    Not exactly sure what you mean, but I'll give it a shot. If on the back of your reciever/amp/avr you have a sub out, connect the sub there. If your other speakers are running fine currently, nothing will change. There will be no added stress to your amp. If your amp has a speaker set up program, allow it to control volumn for speaker matching, other wise you will have to adjust the sub.

    The sub will have every connection diagrahm that currently exists.

    Hi again. Dat means the 45w from the amp will be fed indirectly to the main speakers via the sub speaker in/outs?does it work that way?thanks so much again..

    As far as I know the speaker terminals act like a line output converter. Meaning only the low frequency is "stripped" from the speaker cable and sent to the sub amp while the mids and highs are passed through to your speakers

    Your 2 channel amp will provide the power to your bookshelf speakers via a pass thru on the sub. The sub will provide it's own power thru it's built-in amp. The setting on the sub crossover will determine which frequencies go to the main speakers. Use the volume on the sub to control the sub volume level. Once it is set you don't need to touch it again. Use the voulme on the 2 channel amp to control the sub and speakers together. The power ratings are not important.

    Home Theater:
    Vizio V585-H11 ~ Yamaha RX-V800 ~ Furman Elite-15 DMi ~ Marantz DV6001 ~ EPI M90 ~ Polk Audio RT35i ~ CS400i ~ (2) Polk Audio PSW450

    Carl is correct. I am not positive that the psw110 has a built in high-pass which filters out the lower frequencies from going to your monitors, but it will does at least have a low pass. It should work, though as always better options exist. I always encourage people to go used. I have purchased about 15 different powered subwoofers over the years, only 2 were new, and I have never had a single problem with any. I will highly recommened this http://app.audiogon.com/listings/subwoofers-outlaw-audio-lfm-1-compact-subwoofer-2013-05-06-home-theater-06037 over the polk.

    Good luck!
