I'm interested in adding an isolator to my car, but how big of one?

How do I go about choosing the correct size isolator for my setup? I'm currently running two air compressors and 2 amps totaling 2000 watts. HELP! The isolator that I'm looking at is the Stinger SR200, but i'm not sure if this i sufficient. TIA

uh, why? just wire up your **** in parallel, either way the load on your alternator wont be much different. How many batteries do you have to start with?

I'm looking to add a second battery. It would be pretty smart to add an isolator just so the main starting battery doesn't drain from the audio/compressors running while the car is off. //content.invisioncic.com/y282845/emoticons/suicide.gif.a649d21efc0d1fd4890a6428166586c1.gif

Not that id know about anything like that //content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif
