If you don't mind. Would you explain to me how to hook up 2 subs to 1 amp and is there any neg. to it?
Or is it better to go with 1 amp per sub?
One thing to note about those pro-subs is they do not dig very deep. With that approach you are giving up deep bass for bigger mid and upper bass. The dynamics are enormous, and they do get very loud, but the 3635 is -10 by 28 Hz, and the 4641 is -10 by 25 Hz. What that means is there isn't a whole lot of output under 30 Hz, and those subs will struggle with frequencies below that point, ie lots of distortion. They also have to be equalized for as flat frequency response, so you will want some kind of EQ system with them. I wouldn't rely on Audyssey for a flat frequency response, especially since you are only getting one sub. A single sub system presents its own problems as well.
I think the JBL 3252 speakers would be great, especially at those prices, likely better than the QSCs for your application, but be aware they are 4 ohm speakers and will present a heavier load on your receiver than normal speakers. However, they are so sensitive that doesn't look like it should ever be a problem unless your AVR turns out to be especially shoddy. The JBL 8320s should be better than my Hsu bookshelf recommends as well, especially at those prices. As for the sub though, I would not want the JBL sub though, it rolls off too high. You will be missing a lot of deep bass content with those. It is a more appropriate match for that system that the Hsu subs I recommended because the huge dynamic range is more in line with the JBL fronts, but A) you are very unlikely to get a flat response with just one sub, and B) very little deep bass at all. I would go for something like dual Hsu VTF15h
s or dual SVS PC12 Plus
subs, they won't get as loud as the JBL, but they will give you deep bass, a flatter response and thus a more accurate sound, and they will be much easier to setup because you probably won't have to do any EQing outside of room correction from Audyssey.
