I have this happen but only when i max out my system when the car is off. That was on my civic though (smaller battery). Your system is just taking too much power from the battery, and something is shutting the system off as a precaution, instead of killing your car. Get a decent sized cap and you will be fine because the battery will get drained at a constant rate instead of drawing large loads all at once, causing the system to shut off. I dont know if you can justify buying a bigger battery for the size system you have though. Any bigger and I would say yes do both but you should be okay with a big capacitor.
