as you can see, with all this information flying abou the place it's a bit difficult to actually get to the bare bones of what i need/require as opposed to what everyone else has done or thinks should be done or feels should be done in each individual case
i know the alarm kills the battery so i've sorted that out, let it passivly alarm and use the nornmal key to lock the car and everythings fine, if i lock it using the alarm it drains the battery like no one business
Apologies for hijacking your thread earlier.
If you really want to add another battery just for audio use then the simplest method would be an isolator style relay that way you can charge both batteries and have them isolated so when the audio battery depletes you are still able to start the engine.
Look at Fleabay item 400023614561 , i have usedd this to good effect.
Easy , simple fitting and with step by step instructions.
Ideally add sealed battery as you dont want noxious fumes in the car.
