I pulled my amp and sub out for a while and left everything hooked up. when i put it back in the amp wouldnt turn on. even though everything is the same and the fueses are good.
i didnt think it would have blown, when i bought the car the wires wernt taped up or anything. but i guess that was an old HU lol anyways. i was thinking to connect it to an ignition source but i wasnt sure if that would work.
