Threw a pair of these in a prefabbed underseat box that matched their specs in a 2017 Silverado extended cab and was completely blown away. Have them wired down to 1ohm being fed by a very small in stature NVX NDA12001 and wow. These subs are very impressive!! From the amp to the subs, we couldn't ask for anything more. They woke the truck up and would rival some systems twice their size. If you're on the fence on these, concerned about the shallow mounting, don't be. I was, and I was wrong. I'm definitely blown away. Way too go NVX, great selection to bring to market!
