has it worked in the past? are you sure the install is correct? could be a faulty ground, reversed polarity, power wire hooked up to remote wire, ect need more info. |

An amp can go into protection mode if over driven or under powered.
For example, the power drops below 11v or you set the gain/level to 1v and send 4v. |

it worked fine and i checked all the wires. it hardly takes any power b4 it goes into protect
i think the gain was fine about 2.5--matched with the HU
i just got a new battery and it didnt have enough power to make the alt drag
is it just broke? |
