It's terrible! That is if you want to hear music with the windows open and doing anything over 55 mph. I haven't stripped it yet but I think we have tucked away: 1" tweets in door, 5.25" mids in door (I hope), and 6 by 9's in the rear. I have to toss my stereo in my R in the coming weeks. Alpine CD, PPI A404 (Art Series old school baby, but two months old) and two A/D/S i345 component sets (bad-ass). Maybe a 10" sub with A200 and Epicenter for depth but not too heavy. Just keep performance first and cosmetics and entertainment second.

P.S. I couldn't have said it better myself:

"I was too busy enjoying the mechanical orchestration provided by vtec at 8000 rpm."
