[QUOTE="FoxPro5, post: 3958703, member: 562649"] Amazingly Loud SQ...ALSQ?? [IMG]//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif[/IMG] Sorry, had to. Take an SLP reading where ALSQ is right now. Say for ex it's 130 dB. Consult the literature on the Rainbow Profi set and make sure the drivers can play to 140 dB before the phase plugs shoot out of them like a cork on a bottle of Korbel that's been rolling around the trunk of the limo on prom night (I'm only half jokingly serious here). To get to 140 dB from 130 dB you need about 8x the power. Break it on down (assuming your current amp puts out 100 W) 133 = 200 watts 136 = 400 watts 139 = 800 watts Consider the efficiency of your typical Class A/B at 60% or so Consider that your car only does 13.5v and not 14.4v (~10% drop in power) Start your car and drive down the road at 70 mph = maybe a 6 dB loss?? Solution: buy 11 batteries or a disel powered generator. or Learn to tune! [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] [/QUOTE]
