[QUOTE="blazian87, post: 8444896, member: 574798"] It would be safe to say that it does 1500 @ 2 ohms. Some people claim that it does 1800w but there's no bench test to prove it. Even if it did a few hundred watts more than 1500, you wouldn't really hear that much of a difference anyway. You usually need to double your power to hear a 3 db increase if all things equal. The DMM method works well if you know what your rms target is but it doesn't show you where the clipping point is. The real way of getting the most juice from your amp is either a oscilloscope or a SMD DD-1. If you don't wanna spend the money, then just set it at 1500w and call it day. It's not that hard. Just look at the tutorial videos again. Just gotta do a little math then have your dmm read the output as you turn the gain up to your targeted RMS. Also, for your speakers.. since I'm assuming you are running your speakers passive and using a 4 channel amp for your front and back speakers, then you do the same method as the sub amp. Just look up what your speakers are rated for. Most are usually around 100w. If they are being ran active, then you need to do them by ear. [/QUOTE]
