The other day my sub amp was kicking off cause my back battery was dropping to like 10 volts. Im charging it back up now and dont know how high i should get it? Also cant figure out why it got so low. Both fuses are still good so it should of been charging off the alt.

if you have a decent charger, it'll stop charging when it's ready.
