### ⭐⭐⭐⭐⭐ Good product will buy again
*by A***R on June 14, 2021*

Had the amp wired up to my double skar 5000w loaded pack, pushed out plenty of power and sounded amazing had the wipers in my jeep bouncing an inch off of the windshield lol. I definitely recommend because it wasn’t breaking the bank while still pushing out power
