But Before I take back seat out again and now also front seat out so I can get at amp and use pass thru pre amp signal to go to sub instead of sub out on deck.... Is there any chance that somehow my 12 volt power supply could be causing this?... it reads 12 volts on meter.... But in your vast experience have you seen a power supply cut on and off like it is?
Absolutely. A quick check to verify is to simply disconnect the switched +12v (remote turn-on) at the Tube annd connect it directly to the constant +12v connection. If the Tube plays non-stop, you've found the culprit. If not, you know what you are dealing with.
