Okay so I just bought a Fosgate 10" sub to replace my old one (not realizing it was an 8" OEM), but has anyone every done this yet: fit the 10" sub in the 8" slot...so far I figured I might be able to mount it from below (using maybe a wooden spacer or just something so the sub won't be touching from below the hole) just my idea so far, any other thoughts or ideas on how to fit a 10" sub in the 8" spot?
