Hooked up new speaker and it was still crackling! The guy called tech support and the suggested that it could possibly be a ground wire. Is it possible ?If so where do I found a wiring diagram for this ?

Depending on your setup your amp should have two larger wires attached to it - one to the battery (usually red, but doesn't have to be), and one ground wire attached to the frame(usually black, but doesn't have to be). Some amplifiers have the connections printed on them, but if yours doesn't you may need to check the manual.
