[QUOTE="winkychevelle, post: 8814197, member: 611804"] I've answerd that numerous times. The mic goes in front of the box 1-3feet from the subs. Both inside and out of the vehicle. And when measuring the response curve outside the vehicle you want to face the box away from any hard surfaces that could reflect back at the mic. You don't have to use your current box. A simple spare sub in a sealed box could just be sat on top of the seat inside and then ran outside with a decently long run of speaker wire. Idk if you could use a pressure meter to measure the response curve, I don't see why not but I've never done it that way. You use a frequency sweep not really tones but I guess if you had to manually record every hz 28-80hz you could run the 52 different test tones. [/QUOTE]
