sorry to post so many questions, how exactly does the PAC-200 work? I know it isolates the battery from the main battery but i want to know what happens when the remote turns on and off... really appreciate all the responses

It's a relay. If you know how relays work, then you should understand that. If not, basically what it does is allow current flow to/from that rear battery only when the car is on (when the isolator senses voltage from the turn-on lead, wherever that may be from depending on how it's wired), and shuts off that path to the rear battery when your car is off. It's beneficial if you play your stereo with your car off, so that if the battery powering your amps dies, you still have your front battery fully charged to start your car, which will then recharge your rear battery. Make sense?

does it matter where the input voltage is coming from? Mine is off the remote of the head unit...

I thought you said you already ruled the isolator out? Test it by measuring the voltage in the rear with the car on.
