[QUOTE="LoneRanger, post: 75116, member: 540903"] I got my MECP booklet right here beside me and nowhere in here can i find the term box impedence....maybe i'm not looking hard enough. The test I performed on the amplifier took ratings assuming the impedence of the driver was that stated by the manufacturer. I figure it this way: I use my amp exclusively on audiobahn subs. If they say it's a duel two ohm coil, then to me, that's what the amp does in one ohm mode.....same goes for the duel 4's making a 2 ohm load......I know that impedence changes with the note being played and also as a factor of heat dissapation.....just seemed to take entirely too much math for me. For the test I used sealed boxes that were fabricated by the owners of the subs. If my memory serves me correctly, the AW1506Q was in a 1.0cuft and the AW1505Q was in a 1.25. I know by extensive testing with my own equiptment that the loudest frequency my truck will play from the rear center of the cab is 59hz. I used the MECA CD and that handy-dandy pioneer track looping feature to ensure this note was played during the testing. The power supply will not drop below 13.8v constant supply at the back distro block. It has been measured peaking as high as 14.4v. If you can awnser your question with this information, let me know.
