I purchased 2 zvx15v2d1’s and I got to say they definitely delivered what I wanted. They slam for sure! I got the dual 1 ohms and built a massive slot ported box tuned to 28hz and they absolutely get down!! I love them and I’m very happy with them. I’ve heard a lot of bad mouthing about skar but at the end of the day whatever makes you happy is what counts! I upgraded from a single L7 15” kicker so it’s definitely way way louder now! Lol. I love my zvx’s, they get down n low and rattle the shit out of everything! So if your wanting some badass subs that pound these will definitely surprise you. Don’t be scared to try them out. And they package them amazing so you don’t have to worry about them getting messed up!
