Ok Heres my new plans. I have the money to get that Audiopipe AP1500D and a Sundown Audio SA-12, but should i get the 2dvc to get a 4 ohm load or get the 4dvc to get a 2 ohm load? By the way I have a box that i could temporarily put the 12 in. I currently have a RF Punch 501s amp installed im gettin rid of.
