I had a Alpine IVA-D900 & AudioControl EPIC Four.1 in my Tacoma...just recently swapped that out for a new Eclipse AVN726E minus the EQ since I don't have room for it. Now when I turn off the key, the sub will make a faint thump/pop. What is causing this? The installer (Eclipse/JL Audio authorized dealer) who worked on my truck for years says its a normal on/off thump/pop...I don't think so...because the Alpine never had this and they installed that too. Help?
