Trying to find a solution

[01Tahoe-ss]

Looking for a solution have a 2001 Chevy Tahoe ss want to replace factory sub looking for ideas.

Little shallow 8 inch should fit inside the factory enclosure. Or build your own box that fits in the same space and spec it to a sub once you know how much volume you have to work with

Pull sub, measure the ohm on sub, go to parts Express find a matching ohm sub, replace sub
