jujumantb knows what it's all about.

It's not about volume per se, it's about crisp, clean sound... and maintaining that crisp, clean sound even at high volumes if you so wish to listen to it that loud. Take a stock car stereo system (yes, even those Bose and Monsoon and whatever systems are still stock crap) and compare it to a nice custom system and the difference is like FM versus XM.

I used to be real heavy into car stereo systems in high school. I had (still have, just not installed):

Sony CDX-M600 (50Wx4) head unit
Sony 9-band equalizer with seperate subwoofer volume and cutoff frequency controls
2x Infinity Kappa 693i 6x9s
2x Infinity Kappa 425i 4" rounds
1x JBL 12" 1000W Intercooled Competition subwoofer
2x Orion 200Wx2 amplifiers for the Infinity's
1x Kenwood 1000Wx1 mono amplifier for the sub

It was loud, it was crisp and it was clean. I loved it.
