Yes, I've posted about him before. I have his N774 LOC in my 6 and it works very well for me. If you read his bio on the site or hear other people talk about him, he seems very well respected and has had a long history in the car audio community.
LBJay, he runs the tech section over at the www.carsound.com forums. He's not an audio knowledge god, but he's about as close as you can get. I disagree with a few of his theories, but that's just my personality. =)
