Installing "replacement" subwoofers can be very costly, Factory Cadillac subwoofers are indeed very tricky. You must first purchace the proper sub, then install it as you would any other subwoofer. Your best bet would be to install an aftermarket sub and amp due to the costly BOSE system. If you choose this route you may also need to purchace a RCA adapter, and a factory amplifier bypass harness.

Remove the wiring harness from your 2001 Chevy Suburban sub woofer. Remove the sub woofer retaining bolts. Reverse the process to install your new sub woofer.

Make sure that all voice coil jumpers are connected propertly and then run your wires to the amp and your all set.
