Hoping someone can help.
I want to add an Audison active sub in the boot of my car.
I’ve been researching everywhere and still confused as to the correct wires to tap into for my LOC before it goes to the sub.
The pnp adapter that nearly everyone seems to mention is not available to us in Oz so that leaves me with having to tap into existing wires.
My understanding has always been that the LOC has to tap into the signal BEFORE the amp, ie coming from the HEAD UNIT or have I got it wrong and I tap the wires after coming from the AMP or the wire of the underseat sub?
Appreciate your help😊
