How powered subwoofer wiring diagram Actually Works
Here is a breakdown of how these components connect to bring your audio system to life.
The Power Delivery System
An in-line fuse must always be installed on this power wire close to the battery. This fuse protects your vehicle from electrical fires in the event of a short circuit.
The Ground Connection
This connection must be completely free of paint, rust, and debris to ensure a clean, hum-free audio signal.
The Remote Turn-On Wire
The remote turn-on wire (often labeled REM) is a thin wire that connects your subwoofer to a switched power source, such as your aftermarket head unit or a fuse that only gets power when the ignition is turned on.

[IMAGE5]Common Questions People Have About powered subwoofer wiring diagram
Where do I connect the remote turn-on wire if I have a factory radio?
Look for a fuse that only receives power when the key is turned to the "accessory" or "run" position, such as the cigarette lighter or power outlet fuse.
Can I run the power wire and audio signal cables together?
The high current flowing through the power wire can create an electromagnetic field, introducing a high-pitched engine whine into your audio system. Always run power down one side of the car and signal cables down the other.
What size fuse should I use for my powered subwoofer?
Always consult your unit's manual, but as a general rule, match the in-line fuse at the battery to the fuse rating found on the chassis of the subwoofer itself.

Things People Often Misunderstand
Myth 1: You must replace your factory radio to get good bass
Most modern powered subwoofers feature built-in high-level inputs, allowing you to capture a clean audio signal directly from your factory door speakers.
Myth 2: A thicker power wire is always better, regardless of the system
Always refer to your specific system's recommendations for the correct wire gauge.
Myth 3: Any metal bolt can serve as a ground point
The ground point must be scraped down to bare, shiny metal, free of any paint, primer, or rust, to establish a true, low-resistance connection.
