[QUOTE="uptwome2007, post: 6197158, member: 584230"] I'm running 4 of the Sundown Audio SA-12's in my 97 Honda Accord wagon. The box is 5 cubes including the port and it is tuned at 40hz. I burped them on a Stetsom 10kd wired down to .5 ohm. Here are the results....... Burp Frequency......51hz AC volts..........99 Amps..............78 Box Rise..........1.26ohms Watts.............7722 DC Voltage Drop....11.2volts SPL.................151.4@ 51hz All of my measurements were taken 5 seconds into the burp. Each speaker was getting about 1930 watts for the burp!!! That is not bad for a 600watt rms rated sub. I burped them a few times just to see what my peak frequency was, and at no point did I smell any coils or hear them bottom out. Props to you Jacob for building a hell of a mid-level sub!!! ***I also have a box for eight of the SA12's but I didn't have any help to get it into the wagon, so I do some testing with that once I get it in the wagon, and I'll share my results then.
