I just got done testing the 12k in 2 different applications.
The first test was done in the Mini Van with 4 XL 18s and 4 D3100s starting voltage 14.2.
The second test was done in my truck with 6 Level 3 15s and 5 D1400s starting voltage 15.4.
Van results: Starting ohm load is 1 ohm bridged
30hz- 49A x 141.7v= 6943.3 watts @ 2.89 ohms
35hz- 39.89a x 144v= 5744.16 watts @ 3.6 ohms
40hz- 46.8a x 137.8v= 6449 watts @ 2.94 ohms
45hz- 47.3a x 137.4v= 6499 watts @ 2.90 ohms
12k Rated power
1 ohm bridged 12v- 8400 watts
1 ohm bridged 14.4v- 11000 watts
1 ohm bridged 16v- 13000 watts
2 ohms bridged 14.4v- 6800 watts
4 ohms bridged 14.4v- 4200 watts
8 ohms bridged 14.4v- 2400 watts
Now for all of you that hate on those results saying "Im paying for 12000 watts but im not getting it so I am going to be an ass and flame the results"
This second test was done in my truck running 6 Level 3 15s starting ohm load of .67 bridged. Voltage started at 15.4 and dropped to 12.5.
30hz- 97a x 117v= 11349w @ 1.21 ohms
35hz- 95.2a x 123v= 11710w @ 1.29 ohms
40hz- 86a x 129v= 11094w @ 1.5 ohms
45hz- 78.2a x 134v= 10478w @ 1.71 ohms
I believe this is proof for all of those that hated on my original clamp numbers that the 12k is well worth the money you pay because it does well over rated power.
