I found the power limit to my 160v4. I have it crossed over at 40Hz. I was watching Black Summer with the 1500-3 in the mix. The Onk was at +5...LOL! I was pushing a little over 900 peak Watts into it. It's rated for 1000 peak Watts. During those peaks, it sounded a bit squirrelly although any guest at my place would not have noticed. I crossed it over at 80Hz and all was good.

Incidentally, when the planes and gunshots were going on at that +5 gain, it scared the bejeezus out of me and my heart kept skipping beats. I had the M100s on full range. They are normally crossed at 80Hz when driven with my Onk.
