Running the RP15001D amp pushing A single XVF D2 wired at 1ohm. In a 2019 Silverado crew cab. The gain is set at half and i’m kinda worried it’s going to rattle my new truck apart hahaha!!!! I borrowed the sub from my house system, which currently has 2xIX 8’s, 2xSDR 15‘s, 2xSDS 18’s, 2xVXF 15’s!! To 10,000 W, two 3000 W , One 4000 W pro audio amplifiers. It’s absolutely amazing!!! Waiting on my custom under rear seat box to get built which is going to have 2xL7S kickers. Can’t wait to see the difference I don’t think they’re going to be able to compete with one VXF 15 But we’re gonna find out LOL
