Would it give my components a negative effect if I place the cross over in the rear next to the amps? Black Friday should be good to me trying to purchase all my equipment while I have time to install everything!

 

Nah it shouldn't. I had buddies do the same thing, and it worked just fine.

 

The back wall next to the amps is a much better option than in the doors like most people do it. Keeps it safe from moisture and damage from movement. I have mine mounted on the backwall right next to a 2ch amp. Check my gallery or install thread for pics.
