Sounds like a solid plan to me.

I used 12 awg wire, Jantzen coils, Genteq oil caps, and Dayton resistors in my Markwart 604G xover build. I ended up using fixed resistors instead of an Lpad.

J Markwart did a great job designing those crossovers! I'm sure you will like them. Post some pics after you build yours
