I will admit the SKAR DDX 12s do hit harder but for the price difference the HYANKA 12s are very close to the DDX bass output.
Skar DDX 12 are @2ohm load on amp. Hyanka 12s are @2ohm load on amp. watch the comparison difference videos of the skar vs Hyanka
taramps @2ohm dyno at 3,250 rms@ 12.6v
HYANKA FTW
