I maybe putting to much concern into this but I need to ask about this wiring.
I have 4 sets of MB quart qsc 216 6.5 component speakers systems. each set contains 2-6.5 and 2 tweeters and 2 crossovers. When wired they are a 4 ohm load with one 4 ohm 6.5 and 1 4 ohm tweeter per crossover. I am building my own speaker cabinets for home use and I am using 2 sets per speaker cabinet( 4- 6.5 and 4 - tweeters). My question is can just 1 crossover be used to wire all 4-6.5 speakers and 4 tweeters by wiring the speakers in a series - parallel configuration without damaging the crossover. I am sure I have the power to drive them. Im using 2 NAD 214 bridged and 2 NAD c270 bridged in a bi-amp config, the 214 are driving the components and the c270 is driving the subs.

In electrical terms yes it's fine to do that as the impedance ends up the same. However your crossover will probably not like handling 4 times the power it was intended for.
That's the part I was looking for richie00.
May I ask is it ok or a no-no to then run the crossovers in a parallel-series config. That's 4 crossovers per cabinet with each being a 4 ohm. Or should I buy a crossover rated for 500 watts or more?
I do understand that this might not be the best of configurations and there more than likely a better way, but I got all 4 sets of the speakers brand new in the box unused for less than what one set I seen costs on ebay. Less than 200.00 for all 4 sets.
I do appreciate any all help for I am not an expert, just an enthusiast that doesn't mind elbow grease.

The problem with trying to use one crossover would be that you would have to buy a generic ready made crossover which will undoubtedly not give a result anywhere near as good as the proper crossover. So that leaves you with connecting each crossover to a pair of drivers as intended, then wiring each of those four crossover inputs in series-parallel.
Double tweeters are not *optimal*
Probably a X2 power crossover -which means: lower AWG wire in coils for lowpass - and X2 power tweeters should do fine.
Put a midrange and let the magic begin...😱

With the NAD C 270 in bridge mode the load should be 8 Ω at least.
So the woofers need to be series connected.
I haven't played with bridged amps nor series woofers, so I can't tell.
Double diaphgrams should be used well under pistonic range, I'd say about 300 Hz, that's why a midrange should get into the system.
Then there's the fact that LS's designed for car applications have different priorities; probably double 6.5" on open baffle should do fine.
I'd say : get rid of 4 Ω speakers if your intention is for home hi-fi listening
Amplifiers are likely to augment distortion rates when the load is low.

Keep it simple - use one NAD 214 in a normal stereo mode for two sets of MB Quart QSC 216 (one set per channel). Likewise, the second NAD will drive the other two QSC 216 sets. Each channel of the amp will see 4-ohm impedance, so everybody will be happy.
Make two interconnect cables in a Y configuration - to drive two amp channels from one signal source channel.
