Questions on PPI P65C3

[baron_of_bass]

Hello, 

So, I'll be starting a build in a big rig soon, and have a few questions that I was hoping you guys could help me with.

1. Anybody run the PPI P65C3 components in a passive set up? If so, what are your thoughts on these components? 

2. I was thinking of running 3/4 sets of these, and run them off a 2 channel because all of these sets of components will be the "front stage". I wanted to stick to all amps being the same brand and was looking into either sundown or ampere. I couldn't find that they make a 2 channel, so can I use a 1 channel per side (left/right)? Or what would be the best way to hook all 4 sets up? I'm trying to use lease amount of amps possible. 

I want to go passive so I can save some money, if that's what possible. 

Any advice would be appreciated. 

Thanks guys
