140db means nothing to me unless I see what frequency was picked up at that. 150db with horn tweeters isn't hard at all, of course you're measuring it at a wicked high frequency.

I'll bet money that's well over 140db at less than 6ft.
Direct function of my gain? Did you read what I said? It's PROVEN from me and every amplifier manufacturer out there, the lower the voltage, the quicker the amplifier is going to reach it's clipping limit. I swapped my alternator, and didn't touch the gain. My voltage on a song would clip heavily at 12.0V, then new alt and it would be a clean signal at 14.0V, how are you going to tell me I touched the gain?
