Welche endstufe HT’s

Will do it in english, antworten in Deutsch ist gut

In the car I have micro precision 7 HT’s, micro precision z170 Ltd TT’s on a passive mp7 filter. Amplifier is a original human Reign hr2 with 2 x 450 watt rms. I love the attack and dynamic of a powerful amp. The subs are playing on a second HR2.
I want to go active,
Should a use both soundstreams for active? ( 2x450 watt is a lot active on tweeters, or should I buy/ use a lighter amplifier on the tweeters?

Please keep this setup, also for active use, really

It's not only a optical highlight, more power means (often) more control too. So why dont't keep it, if you already have it?
Theres nothing better for really loud listening than outrageous Control on the tweeter and midrange amp.

Only my humble opinion.

German Translation/Free Translation:
Behalt die HR am Hochton, alles andere wäre ein Schritt zurück.

That’s also my first thought. The second HR2 is powering two ultimo 2 ohm versions now with 2 x 900 and that’s going well.
I’m afraid if I put a less powerful amp on the tweeters that it wouldn’t sound the same.

Either the HR2 for the tweeter or a HR4 for tweeter and mids.
(I'm shure, you will upgrade the system sooner or later.)
