Hey everyone. I wired up two- 12" alpine type E subs the other day, to a 600watt alpine amp. They bump pretty good up to about volume 13, (alpine head unit as well), then my whole system turns off and reboots when I go a little higher. It flashes maybe once then it goes off. Any theories behind why this happens? It's a 1998 cavalier-STOCK that it's installed in. Any help greatly appreciated. Thanks in advance!

What part of the system goes out? If its' just the sub amp cutting off, it could very well be an impedance problem. How is it wired?

Head unit shuts off? or amp shuts off?

Everything shuts off. So I guess the head unit must turn off. It like flickers with bass, then goes out. Subs are plugged into a mono amp, so they are wired one sub to the other. and one of them is plugged into the amp. But They work fine until like the Alpine volume level 13+. Thanks for the help so far!

could be the head unit itself or a power draw problem from your charging system. How are the subs wired? Make sure that your amp is stable for the load your putting on it.

It's a mono amp, so it is stable how I have it wired. it's a alpine V12 amp. My friend jsut said he thinks that they take 14.4V. Is that right? If it is, then it could be my alternator is too small right?

Test for voltage across the amp's power and ground terminals as the system cuts off and see what you get.

hmmm. Would that be the same thing as my display on my amp? It says 14.X usually. X usually is between 2-8. Or do you mean, check to see if where I have it grounded is enough for how much power is going through? do you think it is a problem with my amp? Cuz you would think that my whole deck wouldn't turn off. But ur smarter than me. How do I test that?

I figured out the problem. My alternator is not big enough, and my battery is not good enough....stock battery and alternator. I called ALPINE tech support. So thanks for all the feedback guys!

This also happened on my brothers girlfriends cavalier running two memphis subs at 500 watts total. She upgraded to an optima battery and she could take the system up to 20, but anything above that and it still cut out.
