Hi Guys
I have one paradigm PW200 and one Polk Audio PSW125 can I connect 2 @ the same time to get more bass from it or not. If yes, then how can I do this. Right now I am using PW2200 and it works great.

Sure, you can connect two subs. You don't mention the make/model of the AVR, which would help us help you, but if it only has one sub out, simply use a "y-connector" to go to the two subs.

Thanks 57 for replying. I have a Yamaha HTR 5060. Now right noe I am using a regular (AV cable) to connect my AVR and PW2200... Should I be using a coax 75 ohm type of cable or some especial cable. I am planing to place one upfront by the TV and second one by the sofa where I sit, that means I would have to run a cable of 20 25 ft cable. What type I should use. Please coment....Thnaks in advance.

You should connect a digital audio coaxial cable from the AVR to the LFE in on the sub. Composite, coaxial and subwoofer cables are basically the same - RG6 or RG59 internal with RCA ends. These can be purchased online relatively inexpensively.
