Wow, this thread is still alive. Probably won't be on a Termlab meter tell June, when there is a USACi comp near me. I've had loud setups before and have sat in vehicles that could do a legal 150 dbs on the dash. Not sure where I'm at. With music I'm guessing maybe high 140s. Probably could do in the low 150s with a straight test tone.
I'm only using an Orion 2500d on them right now. Looking to get maybe a Memphis Mojo 4kw amp. Gotta add another 3 or 4 batteries if I do that though. It's definitely loud and puts some pressure on you, that's for sure.
I'm going to try and post a video, maybe sometime this weekend. I'll put a link on here if I get one up.
