Hi, got it working!!! it was faulty, the guy i bought it off opened the amp up and there was 2 wires into the positive and none into the negative. It works mint now!!

Hi, thanks for your help every1, I think its a faulty sub after all that! My friend tested all the cables with a multimeter and they were fine, I'm trying the sub in my m8s car today. Iwill let you know how o get on. Thanks again for your help

Could be too much power trying to go throught the amp and its just dying, fix this with a power cap, fusion or Vibe have a few decent 1.0 farad caps, also could be just your amps overheating, they are in a well ventilated place yeah? hope it helps

Does the amp have another light onit, if not then it sounds like it's going into protection mode. You should only b turning ur headunit up 3/4 of the way, also make sure Loud is off on ur head unit. Also make sure ur the gain on the amp isn't all the way up.

Hi, i held it against the boot lock point thing, you know the pointy thing, and it did exactly the same. as soon as music comes on, it goes straight off. Arghhh

Its more than likely your ground lead mate, this happened with a mates active sub tube, make sure youve got the ground connected to a clean point with no paint/rust.

Hi, i recently bought a vibe cbra120 and a autoleads 600w wiring kit. I wired it all up. And when the ignition is on the led on the sub/amp lights up. As soon as you turn up the volume, the led dims then goes off. None of my friends know whats wrong.
Please Help:(
