Yellow .- 12 volt constant. Connect to the fuse box where there is always voltage off the car yet. Tip: If turning off the vehicle are lost “memories” of the stereo, the yellow wire was wrongly connected. Turning off the switch of the vehicle should continue to receive the cable voltage.
Dark blue .- Should have power antenna, this cable is responsible for the antenna when you turn up the stereo and down when you turn it off. Make sure it is connected to the power antenna.

What amp to buy?
Buy an amplifier that is stable to 2 ohms, if you’re going to use for purchasing a subwoofer preferably stable at 1 ohm.
Find a suitable place to install the amplifier.
The amplifiers are heated, so it must stay in a place where they can break away from the heat they generate.
Do not cover or install it where it will be locked as this does not allow to detach from the heat generated and eventually damage it.
Neither install the baffle of the subwoofer and the vibration ultimately damage the amplifier.
