Why would a mono amp have a left and right channel if it is designed as a mono amp?  I have a mono amp rated at 500 x 1 @ 4 ohms or 900 x 1 at 2 ohms.  Right now I have one speaker wire comming from the "right" channel going to both subs wired in parallel which should be driving each sub with 450watts?  Correct?  Could I or would it make any difference if I used both channels on the amp and if I did, how much power would I be pushing to each sub respectively? 

Thanks

There is no left and right output from any mono amp. That is a contradiction in terms.  There is commonly a left and right input, which the amp sums internally.  Some mono amps have two speaker connectors, but these are paralleled and are there only for ease of connecting multiple drivers.

Please go to the Crutchfield website and view the Sony XM-DS1600P5 mono amp pictures and tell me what I'm seeing if it ain't left and right out speaker connections.  This is why I'm confused.  Please straighten me out.

It is a mono amp with left and right inputs and two speaker outputs.  Both speaker outputs are in parallel and are connected in the same way internally to the amp.  If Sony labeled them "left" and "right" then it is simply typical Sony idiocy.  It is NOT a stereo amplifier.

Thanks DYohn.  New comers to this industry can easily be confused. 

Cheers

As long as your subs' total impedence is 2 ohms, yes.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
