[QUOTE="PV Audio, post: 6533533, member: 554493"] Being as respectful as possible, but you haven't seen nor heard a true 150+db setup. No two subs getting 500 watts each are hitting a 153.4 unless they're in some sort of tricked out horn enclosure which would be larger than the car itself. They just aren't. Three things determine your output, aside from the vehicle: speaker type, enclosure type, and input power. I don't say cone area, because that isn't sufficient. A 10" RE MT will every day of the week score higher than a 15" Type E even though the cone area is vastly smaller. Why? Force. I'm not going to get into how speakers actually work because you probably aren't interested, but just take this away: to make lots of sound pressure, you need to move a lot of air, and that requires a large amount of motor force. That is why most SPL subwoofers have such high power handling. It isn't because you can brag that you can feed 2000W per coil, it's because when you're feeding that much power into said coil, the force being created with the magnet is going to be making some serious output. Your PRs, as I said, aren't sufficient. If you want to get into the 150 range, you're going to need to both improve your speakers, improve your power source and improve your enclosure. The three things are not independent in the slightest, and definitely all need work to get you where you want to be.
