I have a matts d300hc class d amp it has two negative and positive speaker connection terminals, so now how do i wire my dd3515 sub to 2 ohm load on the amp? it's confusing me because the paper work says "single DVC speaker 2 ohm load" and shows a picture with a woofer and both the positive and negative on the woofer wires going into its own negative and positive on to the amp (which has 2 of each again} I though it should only be wired to 2 ohms inside the box to the wire out terminal to one negative and positive on the amp.
your right amp is a mono so each terminal has the same power they just do that because most people are going to hook up 2 woofers any way so both pos + both neg inside box 1 neg + 1 pos to amp.
