Awesome sub!!

The following review is for SW-M12D1, which is a part of the bundle you are viewing.

This subwoofer is an absolute beast! Build quality is top notch. I got it as an open box deal, which i would highly recommend. Saved me almost $200. The sound quality is amazing! It's rated for 2000w rms, I'm running an alpine amp that only pushes 900w rms, and it's still loud AF. Bass is loud, deep, and clean. Sundown has a new customer fore life!
