The "blue/white" power accessory wire of the harness (which I assume is the orange remote wire at the sub) is spliced to the power antenna wire of my deck. The weird thing is when I have my key at the ACC position, the sub is constantly/continuously on no matter what the volume is. Once I turn the key to the ON position, the sub usually shuts off if the volume isn't loud enough. For instance, after changing songs the sub shuts off, and it takes 3-5 seconds of music playing to trigger the sub to turn back on again. If I turn the car off and switch the key back to ACC, the sub goes on permanently again. This is all with that orange loop connected. If I remove it, the ACC position works as permanent on, but in the ON position the sub does not turn on at any volume level.
Anyone have any advice to offer? I think maybe the power antenna wire from my deck isn't what I was supposed to splice the blue/white wire into. Would it work if I spliced both the red power wire and the blue/white power accessory wire to the power wire for my deck? Any help would be appreciated.
Remove the remote turn-on loop. Connect the blue/white wire of the Tube to the constant power wire of the headunit or the switched +12v. Keep in mind, the blue/white wire is the connection that actually turns the Tube "on." Connecting the constant power and remote turn-on wire to the same source will not be a problem.
