I needed more volume, clearer sound and TRUE stereo from my main speakers for my sound system. Also the way I was running it before wasn't the best idea.
I have 2 15" subs for the low end but my mids and highs were just a set of 12" mains that wasn't enough. I found a pair of horns that I could use but the drivers were blown and nobody made parts for them so new drivers were on order.
After a bit of research I figured out how I was going to wire them up. You can't give high frequency horns bass or they can blow. I needed to get the bass out of the signal to them so I set on making a passive crossover.
I started by taking the old parts of the existing board. 
Then I needed to fit the new parts.
Here is my rough drawing of the how I am going to wire it up. 
And then mock up of how I am placing them
All soldered up and ready for installation
Here are the new drivers.
Everything bolted up nicely
All setup and sounding loud af. I took the covers off of the woofers just for fun.
This years Poineer days are going to be fun!
Hope you guys enjoyed.
