The factory subwoofer is attached to a steel bracker that effectively takes up the entire space under the right rear passenger seat. That prevents installing a second battery, a compressor or in my case a small subwoofer enclosure. After removing the JBL Nano and the bracket it was attached to, I had the entire space to use under the seat. I bought a new wire harness for the JBL Nano off of amazon to make reinstalling it easier and ran wires from the original harness to under the driver (left) seat. It fits like a glove and running the wires from the original harness location to under the driver seat is easy with the removable plastic floor pieces. This is the harness I used. https://www.amazon.com/dp/B0BZVWJ7WK?tag=globalgrena0b-20 Please not the colors are different, but you just need to line up the same locations for the wires and it is plug and play with the factory subwoofer.
