[QUOTE="Beatin', post: 8794185, member: 646085"] Have 2 audiotechnix strato 15's in a 4th order at 2 ohms on a PPI black ice 1800.1D. I tuned it to the head unit at 25 out of 35 to give 500wrms at 2 ohms with a 60hz 0bd tone with a multimeter and got over 31volts at the terminal. I figured if a turned up to 30/35 it would give around 1000wrms, which is what the amp is rated at 2 ohms. Dont know how many notches actually give you that but it was loud and sounded appropriate. I added a third battery and decided to wire down to half ohm. I tuned higher on the headunit, 30 out of 35, to get 31volts at the amp terminals, which would give about 1900-2000watts maximum amplitude with a half ohm load(amp rated about 1800wrms at 1 ohm). Hooked everything up, sounded good but was really soft at full volume compared to 2 ohms!? wtf? I checked the impedance of the subs, they're good. What did I do wrong? [/QUOTE]
