I you have it in a IMAX theatre, why shouldn't it be in your vehicle ?? Wouldn't be the same if it was missing ... DO you sit in your truck to watch movies? Are you competing in the "best theater experience" class of "SQ" ocmpetitions? Nobody is saying you can not do it, and others have with success, but we get into the objective versus subjective debate yet again, like always and any time you bring judging and human ears into the equation, all objectivity goes out the window. If could afford the electronics to watch movies, yes I would ... Yes, I am in Super Modified Class in USACI and Modex class in MECA ... Yea, aparently SSA is saying it can't be done ... This is the game I want to play in, so just like any other game, I have to play by their rules ... just the way it is ... Nobody said it can't be done, and why do you always make these threads? You pose a question, then when you don't get the answer you want, you dance around everything and it always ends up with you twisting shit around. You're like a teenage girl who doesn't get her way and throws a fit. Here's a question for you; since you know guys who have "successfully" used rear speakers and center channels in their cars, why don't you ask them since they know what the fuck they are doing? OR better yet, why don't you ask the judges how to do it and what they want to hear. . .
