Just keep in mind that the alternator on our cars is only 80 amps. Just the aplifiers alone you are running will be drawing well more than that. You need to maintain about a 13 volt system to keep everything happy or your headlights will dim and so on. The added screens and stuff will just add to the amperage draw on your electrical system. My suggestion to you is to put an additional yellow top in the trunk to run all your components, and leave the one under the hood for just the car, and definately minimize the time you have everything turned on when the car isn't running. Then your car will start everytime.

Running multiple batteries on the stock alternator is a bad idea. When you add a 2nd Battery your alternator has to work double time to try and keep both batteries alive. Suggest an upgraded alternator if you're really worried about it or if you run into problems.
