It's a 6" (or 6.5") subwoofer and is amplified with the built in Infinity amplifier. It seems to me that I read it is a non-standard size and is difficult to replace. If you want more bass you should probably get an aftermarket amp and sub. The stereo is proprietary too so you will probably need to replace the CD player if you do, that's what I did. Best buy or another car stereo place can hook you up with the wiring kit for it.
IT is a 8" sub woofer an there is only 1 located in the rear of the car on the passenger side.
if it is a stock sub woofer it should be an 8 inch
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.
