[QUOTE="T3mpest, post: 6833729, member: 560148"] The Q of the enclosure has no bearing. You metered it outside and metered it inside. The only change was the car's acoustics itself. Take actual measured in car at each one-measured outside car the number that is biggest is where you got the most actual gain, that's the frequency your car is giving you the most boost. What's actually loudest is irrelevant, that's why people get confused and are like "my box is tuned to 30, but the car peaks at 42". They say that, but it's usually the box and car combo that peaks at 42, that's a different measurement lol. 43 or 44hz is what your shooting to meter on, tone wise, that's where your car adds the most db's. If you want to try a different location, go ahead, simply keep the old out of car measurements and subtract the new values in that location. Your looking for the biggest DIFFERENCE, not the biggest number... Also, you want to measure close to the cone, but far away from ANY boundaries. At the frequencies your working with, you want to be as far as possible, like 100feet if you can (srs). I live in illinois, empty corn fields in the country work wonders lol. [/QUOTE]
