Cranking amps is what's important with starting your vehicle. As long as it starts my car I'll use it.

Do you have any information that says a battery is important to your audio system once the engine is on? I'd rather not use "experience" since it's wildly subjective and based on a number of variables.

I haven't found any academic proof that says a solid 12V battery source is necessary to run in line while utilizing 120amp/13.6V source.

How many 20amp outlets does your home theatre require?
