I guess that's business and celebrities that go there typically have more money than they know what to do with, and like a fool are soon parted thereof LOL.
As for the average joe, did anyone see that episode where some guy (non-celebrity) goes in there? The funny thing was the guy had to be under 25 and he had a Ferrari I think and he didn't look like he made the money in legit fashion (or even owned the car legitimately, LOL) but when he gave him a quote for like one sub and an amp the guy had to leave because he couldn't afford it. And he went in there with a Ferrari, not like some average car. So you can imagine the insane amounts of money they charge sports players, musicians, etc.
As for Reme v. Mike, I'd have to say Reme because Mike is apparently a clown LOL. I guess on the one hand you have Reme doing simple installs while the guy he works for charges 100x what the installs are worth; while on the other hand you have Mike doing "free" installs for people that have ghetto cars... But I mean out of the stupidity of installs, and his attitude off the show (or so I've heard) Mike still loses, lol.
