Is the power supplied to the stock subwoofer amp constant or switched 12v?

I would say it is constant. I can turn on my stereo without a key in the ignition

The W/D shows constant B+ power supplied to the amplifier on pins 4 an 11 ( OR/WHT ) in color, an 2 ground black wires using pins 5 an 12. The remaining 8 wires are the in an out audio wires for those 2 subs. Whatever that power draw might be on that Amp when power to the car is turned off, must not be very much, or owners would be having some amazing battery problems. Course with a 30A circuit fuse and some sort of partial internal shorting taking place with that Amp, you probably could expect the cars battery to fall flat on its face in short order.

Thanks! I found the pinout that said "battery 12v+" but it didn't dawn on me that it meant constant voltage.
