Zapco dc1000.4 query.

Hey guys I'm looking for some advice or ideas or even confirmation that I am just plain over thinking stuff.
I am putting together a system for my new to me 2005 f250. I ran a four way setup off a p99 in my previous ute and loved it. I really had no dramas with it at all, but as seems to always happen I have some other options for the new build. In the last ute I ran
Hertz Mille tweets and audible physics ram 3 off an alpine pdx 4.150
CSS sdx7 bridged off a ppi 900.4
Focal 27v2 off alpine pdx 1.1000.

For the new truck I have this gear still but now have access to
Zapco dc 1000.4
Phoenix gold zx 450

I suppose the thing I am really interested in is the zapco dc for my mids and tweets, but have been advised that using the simbilink balanced setup will bring in a phase shift that won't be apparent with the other amps. Is this going to be an issue for me or do I need to wait to find a full set of dc amps to really use this big guy.

I'm quite confused by this. But that is not uncommon for me. These dc amps are quite rare in oz where I reside so sorry if this is a really dumb question.
