Question about Sony Xplod XM-554ZR Car Audio Amplifier
You have 3 power connection, +12v goes directly to your vechile's battery (make sure this is fused) REM connects to your head unit which tells the amp when to turn on and off (usually very thin wire, comnpared to the gnd and +12) Te gnd you already know where it goes. Then connect your sub to + and - speaker out put. If you run this bridged it will increase your output, must be 2 channel to bridge to 1 channel or a 4 channel bridged to 2 channels. Hope this helps.
