after market upgrade to sound system maybe drawing to much power circut to keep up with. best to get connections checked and alternator tested for output. compare with system draw. it may also be the battery. if battery is not able to hold enough charge to run components, you may need to upgrade to deep cycle to keep up with system draw. double check and test everything related. audio tech. should be able to address as needed.

Ok so it took me awhile to go back on this site I did the repair 5 years ago
Was on this sight with another problem and saw that I hadn't reposted the fix so sorry

Sorry what happens here is there are a couple of diods in the cabinet control mod that the soder will brake and leave you with a weak connection. Use a magnifying glass to inspect look for a little ring of rust at the connection.
Desoder and resoder connection
