Sundown Audio SA-12 Spl/Power testing!!!

[uptwome2007 10+ year member]

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.

I can take pics of the box with my phone and send them to your phone. Just pm me your cell-phone number. I don't have access to a regular camera at the moment.
