I am looking for an external half space eq and a sub. My alpine hu is too complicated EQ wise and I want something with some knobs that i can turn while driving to adjust the eq. I was looking at the Arc Audio KEQ5 or whatever it is called. For a sub i am thinking 10" as I am going for sound quality and not boom. I was think Arc D10. Any other suggestions? Right now I am waiting on quotes from Don, but I am not locked into these choices. I am looking for quality but as cheap as possible.
