Issue 1: AMP's on but there is no sound. Resolution 1: Could be due to one or more of the following: i) AMP could be receiving the wrong voltage - You must make sure that the AMP is receiving 12V unless stated, a common cause for receiving the wrong voltage could be due to bad connection on the earth cable i.e. Muck and car paint work - remove paint and muck and test connection. ii) Bad connections between the AMP and speakers i.e. broken speaker cable or disconnected speaker cable. iii) Bad connections between the Head Unit and AMP i.e. broken audio cable or cable has been disconnected. iv) Broken Speakers or AMP - retest with another per of speakers or another AMP.
