Had sdr seires witch wer amazing.upgraded to the ddx 10 an o my how thay pound an shake the ground
I purchased 2 ddx d4 10s and I am so happy with them once broke in they amaze me everyday.
I have owned several skar audio subwoofers but I received my first zvx12 d1 and built a birch enclosure tuned to 34htz on a Memphis mojo 4k amp,stinger sp2250 aux battery and sky high 0g wiring in my 02 bmw 330ci and it is hands down the loudest single subwoofer system that I have ever heard! This thing is incredibly loud and LOVES power thrown at it! Repping skar audio in Savannah Georgia!
Running 1 Skar zvx 12 in my Chevy Malibu on 1500 rms tuned to 38 Hz in a 3.5 Cubic foot Box at this thing pounds
