[QUOTE="winkychevelle, post: 8812414, member: 611804"] No that means you cabin gain is fairly low frequency but you might not be gaining a lot compared to other vehicles. Best way I can describe finding cabin gain is to take a driver in a sealed box, outside the vehicle, pointing away from hard reflective surfaces, measure a sweep at 1foot distance in front of the driver Put that same enclosure in the vehicle and run the sweep with the mic at the listeners position. Subtract the original outside sweep from the inside sweep and that is you cabin gain. Basically you are comparing how the sub acts in an open environment compared to the enclosed vehicle environment. It doesn't have to be any particular driver I usually use a random 10inch sub. Once you know your cabin gain you can add that gain or subtract it to the predicted curve of a box program [/QUOTE]
