if i have a powered cross over which would i run the componets off of the amp by itself or through the powered cross over than to the componets cross over im confussed help
By "powered crossover" are you referring to an active crossover?
If so, the active crossover gets connected via RCA's, and goes between the HU and the amplifier. And then yes, the speakers would be connected directly to the amplifier.
run your components to the amp. i assume you have some sort of external xover? that is not needed really since your comps should have a passive xover. other then that i don't know what the hell you are talking about
