For sale is a slightly used Skar Audio RP-350.1D 350 watt, power class D monoblock sub amplifier and a Skar Audio SK10TBV 10" 800w mas power dual voice coil vented base tube subwoofer. What you see in the photos is included. The sound out of this amp/sub combo was good, just not what I want (it came in a car I just bought). The sub is dated 2021, no date on the amp but I suspect it was produced about the same time.

Price is $175 plus shipping via whatever method you wish
