amp shutting off?
 

so i have 2 10" pioneers and a 600 watt sony amp and when i bridge the subs and turn my radio up over like 20 the amp shuts off and the protect light comes on but i can turn my radio off and then back on and they will work again. any possible ideas as to why??

Improper ohm load, improper gain settings, bad ground, not enough voltage.

Take your pick. Start with the first possibility and work from there.

how can i figure the right ohm load?

you would need the specs for your amp and your speakers.
