[QUOTE="wickedwitt, post: 7914116, member: 622908"] People running multiple PAs on a channel of an amp typically run them parallel to get power. I wouldn't expect someone to run 3 sets of 8ohm speakers in series for a 24ohm load and 20w of power... That was to be read 1-2 not 1/2 btw. I agree w/ you that pressurizing the cabin to that level will distort the sound, but having PAs vs mobile audio speakers at that point does nothing. With good components and fair amounts of power, MA speakers can be just as loud as PA and sound better while doing it. The kind of pressure you're talking about is going to take that wave and distort it by changing the air in the cabin tremendously. I'd much rather see a MA speaker way over powered than a PA speaker and trashy low impedances causing double distortion (distortion from the speaker getting wrecked by sub stage pressure). Local audio shop has a van w/ 2 sets of 50w RMS coaxes on 300w each. Crossovers are set properly and power is clean. The speakers scream but sound absolutely crystal clear, and keep up with 8 15" wall just fine. [/QUOTE]
