Snooping around a bit, you people amuse me. Firstly, I'm likely older than most of you at 49 which in itself means nothing other than I've had a chance to learn from more mistakes than most of you have. I was also a "genius" at 17 and knew far more than my elders. Yeah, right. Enough of that. I'm not your dad and its not my job to be. Most of my equipment is also likely older than most of you (late '70s, early '80s vintage). My home stereo (McIntosh powered, of course) will deliver 130dB of absolutely undistorted hearing damage. If ANY of you were to try to stand it for an album (yes, those vinyl thingies) side without suffering painful permanent hearing damage (tinnitus) you must be wearing earplugs. It WILL permanently damage your hearing. This is with 300W/ch in a large room and 100dB/W Klipsch speakers. What exactly is the point of ANYTHING hitting 150+dB (which I seriously doubt is possible anyways, you're kidding yourselves). Doubling the power gets you 3 dB. Roughly 128000w at 100dB/W for 151 dB. Then again, you "kids" like nothing but bass (cause it sounds cool???) rather than full range music. If your amps actually delivered the watts they advertise, 100W/ch would make your ears bleed in a full sized sedan, let alone a ratty-assed Honda or other import crap. I drive a full-sized Blazer (kinda like a Yukon for you younger crowd) with 100/ch with 3-way "house" speakers in the back. The rear-view (windshield mounted) mirror is useless when cranked. The lights dim at stoplights with a 250A alternator. That's a REAL 100W/ch amp.
