problem with my subs, it's draining power Options

[poix]

well i connected my subs after being told that i have to conect the remote wire to the yellow wire of the head unit. but the problem is now i have trouble starting up my car.

im not sure what it is but i think the subs are draining the power because even when i turn off the car the head unit is still on, it has a red light the signals as warning. i can see that even when i turn the car off, the amps still light up, which means it is still on. so im thinking since the remote wire is connect to the yeloow power wire, the amp stays on with the head unit.

my car was fine before when i first got the car with the head unit and subs. due to electrical repair on the car, they reconnected my remote wire to the blue wire for the head unit. so my subs ended up didnt work for awhile.

now that i connected it i think its draining all the batteries. i just switch to a new battry, but still having trouble when i started up except if i disconnect the subs.

i have a fuse that connects to the battery from the amps. i dont know what to do now. did i connect the wires the wrong way?? is there other ways to connect the wires to avoid battery drainage?
