Default Is my X350 lacking power?


I am a new member of this forum, living in Norway and just bought a Pass Labs X-350 to drive my Infinity Kappa 9.2i series II.

When pushing very loud volumes, the VU-meters are almost constantly to the far right, and I wonder if this is bad or if there is still more headroom in my amp even if the indicator bottoms out.

I am afraid to send some bad stuff into my speakers and destroy some drivers.

My speakers do drop in impedance to appr. 1,5 ohms@30 hz.

I also wonder if this is something the X350 can handle or not.
To me the bass seems a little out of control, and I wonder if the low damping factor combined with this low impedance is a bad match?

When I connect my other set of speakers, Usher Dancer AC-20 the bass is a lot tighter with the X350.

Thanks for the answer Nelson, for other people interested, this was the answer:

The meter simply indicates current draw, and the amp can draw more current than the meter can indicate.
