According to the Volvo subwoofer installation instructions, you need to insert a pin into the large connector on the back of the REM (rear fuseholder), but that either needs to be enabled to function on that pin as a turn-on signal, or it is a communication bus signal to the factory amplifier. The BassPro is designed to be installed inside most factory spare tires and can fit a wide variety of vehicles.

I used a puncture tool to make initial pilot hole, then electrical taped Power and Remote wires to a phllips head screwdriver.

Will the vibration from the woofer cause any complications with the fuel pump being that it is directly on top of the gas tank because it sits inside the spare? I had no experience with car audio before but had experience repairing electronics/ computers and using power tools. The 11" (279mm) feather-light fiberglass woofer cone with rubber surround delivers the signature kick and punch of JBL bass. The BassPro Hub features a 11" subwoofer with a tough fiberglass cone and rubber surround that'll hold up at high volumes.
