When I took the system out of my other car it worked perfectly. The power light is on so my ground and power is good. The blue wire is hooked up to the deck, the 2 plug in wires is connected to the back of the deck too. And the last 2 wires is correctly connected to the sub. What can be wrong? I set my deck's sub level to max and the sub level on the amp to max. Still doesn't work.

 

You need to check the main battery fuse. Just because the amo is lighting up right does not mean its geting power. It could pull power from the remote lead. Did you test with a meter to see if the remote wire is putting out power? Did you do the same for the power wire? If not you need to check. Makse sure the sub leads did not come loose inside the enclosure

 

got it, the 2 plugs that plug from deck to amp came off. thanks.
