First unit failed
Crutchfield Customer Review (What's this?)
This unit is required for the Mitsubishi Evolution with Rockford Fosgate stock stereo if you want to retain the factory subwoofer amp and subwoofer control. Very messy installation. So many wires. Wires longer than they needed to be. I got the Pioneer stereo I connected up and running. I called it quits for the night and powered everything down and disconnected the battery again for final installation into the dash the next day. The next morning I powered on the car and the stereo would not turn on. Eek. Did I just cook a very expensive stereo? Took to a professional audio installer. Root cause was a failure inside the module box. Luckily they had a replacement on hand and got everything working again.
Pros: Subwoofer control maintained
Cons: Item failed the first time and required a replacement.
