i only got one sub....so do i just split the + into two and the - into two or....run another wire from + to + and another one from - to -? and if i get two subs would i hook it up like a 2ch amp? one sub to each?

Just use on + and one -


Those terminals are connected together inside. I don't know why so many people equate number of terminals with number of channels on amps. It don't work that way.

thats just so u dont have to stuff a lot of wire into 1 of the terminals if u have 2 subs... if u have 1 sub just use 1 side

each + & - terminal will do the same exact job since internally its connected together

they just put 2 of each for conveniencoption instead of some1 trying to fit 2 thick wires on 1 terminal they can use each .......

Well i no on my MB Quart amp it has 2 + and 2 - and in the manual it says that each one is only stable to 2ohms so to get one ohm ive got to hook up a 2ohm load to EACH one to get a 1ohm load. I think it depends on what VC your sub/subs are and what the amp is stable to.

Like on your amp if its only 2ohm stable on each terminal and you hook up a 1ohm load to just one terminal it could mess up your amp.

The reason for the amp having 2 + and 2 - is for easier connections, on the inside of the amp the + connects to the other + and the - with the -. Say you have 2 DVC 4ohm subs wired to 2ohms each...instead of connecting both subs in paralel on the one terminal, you can just connect both subs to there own terminals... better looking and easy to connect instead of cramming wires in there...
