[QUOTE="glennlewis, post: 1315166, member: 564701"] I have a slightly different view.....You should put a voltmeter on the car anywhere in the system and check what the voltage is when you crank up the subs...If the voltage drops below 12.5 volts probably the amp is shutting down due to low voltage....Which is normal....It is true that the alternator is of a low amperage value but if your battery is of low capacity it can affect this equation also. Say your battery is 650 CCA instead of 1000CCA could also affect this situation. The other issue is what is the impedence load of the amp. You say it is 1 ohm. It is possible that if you increase the impedence load to the amp that this shut-off problem could be lessened. If you are running an extremely low impedence load the amp might not like it and is shutting off due to that. Also you mention that you have the Sub Out set at +15...Is this a wise thing regardless of what is thought to be true...my 2cents [/QUOTE]
