well i have a amp (cactus 5kw) and it has four speaker terminals and im trying to hook up a 2ohm load to it. my question is if i hook 2ohms up to it will it be 2ohms or would it bridge it down to 1ohm?????? thanks

if it's a monoblock amp, then it is wired in parallel inside.

A DMM will tell u this once it's hooked up.

It will only parallel connections if you havent done so already.

If your connections are already in parallel or series, running a single line of positive and negative to the amp will not change anything.
