[QUOTE="Ethan Greaves, post: 216574, member: 14552"] Yes, it is easing to know that that is the right way of doing things - this is my first build so I thought all had to be matched. Thanks for the tip and reassurance on amp choices. It is right that the subs need ~2500w each if there are 1250 watt rated ? This is where things get weird for me as I've spent a lot of time thinking about this in last 48hrs, and I'm utilizing the passive FB464 crossover. The DCX464 is technically 2 in-phase drivers for HF + VHF, both - according also to website 16 + 16 ohm. If I am powering the crossover itself to both speakers - is this in fact an 8 ohm parallel group of 2 drivers ? And if they are resistance-matched - they each draw equal power evenly, then should the "program power" amp channel requirement be 320w (220w MF + 160w HF continuous power handling) to suit the more delicate HF driver ? Sorry, brain going on logic explosion Here is crossover diagram: [ATTACH type="full" width="707px"]209584[/ATTACH] [/QUOTE]
