Well, I just only want one amp. Ik i could use a distribution block but I would actually be saving money by going with just 1 amp bc if I got 2 I would get a much better one for the sub. Im just trying to save space in my car tho. I already bought my 3 rcas and speaker wire and all anyways for this set up. I am just going to get the hifonics for 400 bucks or if someone can find a better one then ill get that one.
