i have a question, What if i wired up a 2 ohm sub into a 4 ohm Amp im not Saying im planning on doing this by anymeans i was just wondering what i would do Does anyone know?

 

its probably a 2 channel amp and if it is it most likely can't take a 2ohm load bridged(across both channels). It will overheat. it can use 1 of the channels but that will be underpowering it huge. you need a mono amp.

 

if its a good amp then probably not much, but otherwise it'll run hot and probably go into protection until it gets super hot and dies
