So I bought a spider jam and have 10 minutes or so the amp cuts out an re-boots itself. I've had a 4gb sd in the memory card slot after only just finding out you can only use up to a 2gb, Could this have anything to do with it?. I've also been researching about firmware my amp has the latest version but could re flashing it solve the problem?. Any help on this topic will be gratefully received. Thanks
