Stereo setup question

[Sinkoumn]

Could I get some feedback/input on this setup that I have drawn out below? I'm not even close to being an expert at any stereo setup, so I hope that I can get some audiophile's to let me know if there are any problems with the way that I have drawn out the diagram.

Basically, I'm running off of the XMD3, PPI PAR-650 Preamp, MTX 942 Amp (2-channel for tower speakers), MTX 564 (4-channel for interior speakers), Polk MM2104DVC subwoofer, MTX 801D (Mono amp for Sub).

I would like to have the 4-channel setup in the interior, so would it be a bad idea to set up the system with the Front outputs split - so the signal ends up going to both the Tower amp and interior speaker amp?

To simplify the drawing, I didn't put in the sub or amp for it - the Preamp has a sub output so it will run directly off of that.

I plan on controlling the level of the tower speakers by way of the MTX EBC level control (basic turn knob).

So, will this work or no? I would appreciate any help.
Thanks much.

Your setup should work fine without a problem by just using RCA Y connectors. You do run a slight risk of introducing more noise when splitting the pre-outs, but that is pretty minimal, especially since the PPI PAR-650 has a pretty high output (~6V).
