If you’re looking for a cheap amp to run dual 8" through 12" possibly 15" or mid and highs. This amp will do it. When I ran it through tests this is what I came up with, single 15" dual 4ohm rated 850. Bridged @ 2ohm 266.2 watts 20hz tone. Bridged @ 4ohm 164.5 watts 20hz tone. A change in either direction will decrease wattage.
