[QUOTE="LDW3RD, post: 5268274, member: 548883"] I forget were I read this(maybe in Carstereo review) but I believe it went something like this... I believe your are going to need a RTA so you can measure the db's of the frequencies that you choose. Take a open air(outside the car) measurement of your sub at a given frequency, I believe the mic should be 3ft away from the sub. And then take a measurement in the car at the same frequencies that you measured in open air again with the mic 3ft away. And I believe the gain achieved in the car, above the open air measurement, is what is called cabin gain.. Gotta see if I can find that issue. I'm sure someone on here knows for sure, I also think there is a standard of in-car-gain at given sub frequencies... I believe.... [/QUOTE]
