DIY CAR AUDIO WIRING
How do I get power to an active crossover for my car?
I bought a Soundstorm Laboratories 150x on eBay, not realizing it was active. I’m generally pretty knowledgeable in the means of DIY wiring, but I have no experience in car audio. How/where do you get connections the +12v, remote and ground?
Run a wire of the same size as the power (+12v) to the battery for power.
Ground the unit to any bare metal spot on the car or existing ground connection (best).
Run a fused wire (same size as on the unit) from a fuse in the fuse panel that only has power when the car is ON to one side of a switch. From the other side of the switch run the same sized wire to the REM (remote) connection on the amp.
This allows for full control and you never have to worry about forgetting to turn off the X-over.
You can find fuse taps and in-line fuse holders at any autoparts store.
