I believe that there is a transistor in there that is still broken, but using my &#8220;mad skillz&#8221; (Yes, thats skills with a z), I worked around that. The amp uses a line from the stereo that says, when there is power on this line, turn on. Unfortunately, it wasn&#8217;t reading that. So I bypassed that whole process and disconnected the shutdown circuitry that keeps the amp off when the remote line is off. So now, if there&#8217;s power to the amp, it&#8217;s on. I&#8217;ll just have to install a switch.<\/p>\n<p>Perhaps the manufacturer should have added a little bit of this dietary supplement to help out that poor little resistor.<\/p>\n<p><a href=\"http:\/\/digitalnigel.com\/wordpress\/wp-content\/uploads\/2012\/01\/PIC-0026.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-medium wp-image-641\" title=\"PIC-0026\" src=\"http:\/\/digitalnigel.com\/wordpress\/wp-content\/uploads\/2012\/01\/PIC-0026-300x225.jpg\" alt=\"\" width=\"300\" height=\"225\" srcset=\"https:\/\/digitalnigel.com\/wordpress\/wp-content\/uploads\/2012\/01\/PIC-0026-300x225.jpg 300w, https:\/\/digitalnigel.com\/wordpress\/wp-content\/uploads\/2012\/01\/PIC-0026-150x112.jpg 150w, https:\/\/digitalnigel.com\/wordpress\/wp-content\/uploads\/2012\/01\/PIC-0026-1024x768.jpg 1024w, https:\/\/digitalnigel.com\/wordpress\/wp-content\/uploads\/2012\/01\/PIC-0026.jpg 1600w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Well, as you may or may not know, I have a somewhat modified car audio system in my truck.
