12“ Sundown zv4’s on 7000 watts

Got my subs back in a couple days ago and it already cracked my windshield. Took a quick video of the windshield before getting the new windshield installed. Also metered this system and it does a 153.7 at 38hz for now. Im going to try to get that 154. :) 2 - 12“ Sundown zv4’s 2 - Sundown saz-3500v2’s
