I installed a Stereo system with a kicker AMP. The battery went dead without notice, in a parking lot of a hospital of all places .
But a simple push and clutch pop, it started and drive me to the nearest auto shop and installed a Interstate battery.
BTW, if you ever go though this one, check the web site of the battery you buy. They have specific batteries for specific vehicles. Don't over work, or under work your electrical system. Today I have MSD 6A, Pivot Ground Kit, a ton of extras and the battery doesn't even chirps.
