I'm sure you hear more than we ever could with a camcorder recording played over PC speakers. I bet it sounds pretty good though. Eclipse is known for their clean and high voltage RCAs.
I was trying to find the spec on this unit, but what's listed is a bit general. Time alignment is listed, but i'm not sure if that for 6-position or not(Front L/R, Rear L/R. L/R sub).
It also just lists "crossover".. not sure if that's 2 or 3-way.
C'mon! The system on my desktop is better than most (main) home systems, and I wouldn't dare try and assess the SQ in someone's car via a Youtube video. The idea is absurd.
