Hello. Welcome to Just Answer. Please allow me to assist you. The 12 volt auxiliary battery is insufficient to power any additional accessories. If you add these units, you are exceeding the capability of the battery. All the 12 volt battery is there for is to power up the computers inside the car, not for anything else. The battery is just big enough for what the car needs, and should not be overloaded at all. You might want to look into the OPTIMA line of batteries, I understand the the "d-35" unit will fit thsi car; but I have yet to verify that. You might want to measure and compare. The d-35 is a bit pricey (275 dollars in my area) but worth it if you are going to add units that consume current.
