I've read numerous posts, but i'm still not sure what the general consensus is on the mounting depth of the speakers. I was wondering what the max clearence is for the front, rear, and rear deck speakers. I'm talking about when you add spacers. How many spacers can you add? Did you have to shave anything? Thanks in advance for your help.

 

I'm curious too... have some Boston RC620's and a multi-channel channel amp I'd love to install from my current car if it was actually an option...
