Amp/Sub cuts out when moving

[AcID ZeR0]

Bloody thing been driving me mad for hours.
Right it all started eariler when I noticed my sub wasn't working, wasn't hard (twin 15") lol.
Anyways I pulled over and saw the light on the amp was still on so naturally I checked the wires that go from the amp to the sub all fine had a fiddle with all the wires, then checked the fuse I noticed it was blown.

It was the original fuse that came with the amp and had litrerally exploded inside it had a burn mark on it and smelt of burning plastic, oh well.

Put a new fuse in taken from the cig lighter, both 15amp but the original amp one was a diffrent color, now it's all working fine until I actually move the car.

Start the engine and it's still on but the soon as I start moving it goes off, it will come back on when I'm idling, any ideas please?

Bad connections? Alternator output too high? Don't know to be honest, never heard of an amp doing that before

if it's the fuse on the amp keeps operating then it must be an internal problem with the amp

Sorted it out now thanks guys, just disconnected everything recrimped all the wires and put them all back must have been a loose wire but it was so weird you could shake the wires about and it'd still play but the soon as you start moving the bass would cut completely. oh well all sorted now though - now onto my next problem the squeak lol.
