new to the group and ML

I am also new

I just purchased my new home theater system and am excited to get them completely setup correctly.

TV: Samsung UN55C8000
Receiver: Pioneer VSX-33
Speakers
Left/Right: ML Sources
Center: ML Motion 8
Surround: ML Motion 4
Sub: ML Grotto i

I have yet to install my center/surround speakers as Best Buy is going to come and install my surround speakers.

I just hope I setup my front speakers and sub correctly, they don't sound as nice as I had hoped but I didn't get a chance to run the room auto corrector yet.

Anybody have any suggestions of what I can do for wires? I placed my receiver, bluray player, surge protector inside my entertainment center cabinet but the back is completely filled with wires and I do not think it would be good for venting. Should I place the receiver outside of the cabinet?

I would suggest getting the speakers sounding good before running the processor's room correction. Most likely they're just not optimally positioned.
