The question is, are your amps turned on by a 12V source or signal sensing via RCA/hi-level input?
If its the former, choose a new line or run an extension off of the line for your head unit. If its auto sensing, faulty amp unless it has an adjustable sensitivity (highly unlikely).
Also, if your headunit has a demo mode, that may kill it.
These cars have a 10 min auto shutoff on the lights so you can't do too much damage to the battery.
How so? All of the fuses would blow before that could happen unless you didn't fuse your setup properly. The alternator wire is a fusible link which automatically prevents that source of overcurrent and the line you ran to your amps should be fused (for the total combined amperage of your fuses plus a safety net of say 10%) as close as possible to the power source.
If you really pull too much power, you run the risk of destroying your alt because you'd be using it to the point where it must provide lower voltage to provide the same level of current. On top of that, it'd pull power from your battery. If you really went overboard you could in theory stop your car because it wouldn't have enough power for the ignition or fuel pump. But if its all setup properly then there would be no fires.
