Friends

Suddenly had a change of plans on going 3 way medyo need to go 2 way since i found the pillar mods a bit intrusive for my taste

Im working on a 80 to 100k budget so allocated 30k for install,deadening woodworks and wires

With 50 to 70k what can i do ?

I alreay have 2 4 channel amps already 4x100 each and have no plans on changing HU

Im planning on going focal flax audison bit tem focal p30

Would it make sense to change rear speakers to a coaxial ?
