allout13

it appears that stray strands from the power wire were touching the remote turn on wire causing stuff to turn on w/o the key. I now need to figure out why the amp's power light is on but it doesnt work

why not?

I have no idea what I did, but now both batteries are working properly and the hu doesnt turn on without the key turned. the only problem is that the amp shows power but it seems as if it does not turn on (power up) and there is no output

The front batt is an interstate batt and not agm, the rear batt is a deka intimidator 9A31 which is an AGM. how could that cause a problem?

I know, when I have the money Ill get one, but right now with all of the problems Im having it would be a waste

no one?

This is the first time I have installed a second battery and I hooked everything up as shown in the picture... at first the amp would show that it was getting power but no power was coming out of the speaker outputs. I gave up and turned of the power and removed the keys from the ignition and all of the sudden the amp as well as my hu power back on and the amp is now giving output to the sub. The amp is not putting out near the power it should though and I cannot get anything to shut off. When the car is off the rear batt stays at 12.4volts and does not change when the car is running. With the amp on and the car off, my dmm shows no change in voltage when the bass drops. The front batt is grounded properly. After disconnecting the rear batt the car lost electricity so I checked grounds and made a better ground with the front batt and now the batt in the front rest at 12.3 instead of the 12.7 it was resting at before the problem. now that the ground in the front is fixed I have noticed that when the amplifier is connected to the rear batt is automatically shows power, but still gives no output (when everything is hooked up). as soon as the power wire was hooked up to the rear batt it caused the hu to turn on (w/o key turned on) even though the rear batt had not been grounded yet to anything other than the amp... anyone have a clue as to what could be wrong?
