Sound Storm SX210 2 way Car Electronic Crossover with Remote Subwoofer Control

I'm no audiophile, price aside, would you say this unit is the better choice over the clarion mcd360?

My crossover doesn’t have a harness can I purchase that without purchasing a whole new set up

Not impressed. put a rf noisr in all my speakers. sub gain. goes first quarter the way with no change. then it over does it. ?

Does this come with a harness for the positive negative and remote connection.does not look like wires can be connected to the connections on pre amp
