The RCA jack on the back of my JL F112 Fathom broke. How do I remove the back of the subwoofer to replace the RCA jack.

Use hairdryer or heat gun on the aluminum backplate to loosen seal then removal should be very easy.

It's also important that it is a machine screw so it has the flat end and will not try and screw into the wood. Assuming anything metric is probably a machine screw anyway but not 100% on that.
