I just have a couple more questions now about my system:
First of all, with our tv (which I am now using in my room, with the speakers), it has the video inputs; either Y, Cb, Cr, or Y, Pb, Pr, on the back, and my dvd player has support for both (the terminals say Y, Cb/Pb, Cr/Pr), and i've connected them to the tv using normal rca cords, (btw: I also have the normal single rca plug video plug hooked up) and when i go into the dvd player menu, and change the video type to 'P-scan Y/Pb/Pr', the tv screen goes wierd and distorted for a moment then, it doesn't display the dvd signal at all. Any advice would be very appriciated.
Also, the other of my questions is, with the subwoofer setup that i have altered (see furhter above post that has all the pictures), when i have the sub at the normal level and raise the master volume to about 60-62 (very loud, system goes up to 79), the subwoofer starts to 'pop,' and 'crackle,' and also, something i noticed is that i have had to hook up just one of the drivers, because, for some reason, when i set it up so that there is the main signal going to one subwoofer, and i hook up a second cord to the main to use the second driver, the subs start to pop at much lower volumes.

Any help, advice, or explanations would be greatly appreciated, thx
BTW: Just one last little thing, do you think it would be good/ improve the sound, to lay down some carpet in the room? Thx again in advance to anyone who can offer some advice.
