I would definitely go with the yellow top if you can swing it. My alarm drained the heck out of my battery and the yellow can handle it with out a problem. You are going to need to look into installation issues as I dont believe the yellow fits in the engine bay with the way the post setup comes. You may be able to remove the lower section of the battery tray to gain some clearance or you could do what I did and relocate it to the trunk. Let me know if you find a way to mount it into he engine bay as I am looking into getting another for my and would rather not relocate it again.
