Review on 🔊 Upgrade Your Car Audio System with BOSS Audio BRS40 4 Inch Full Range Replacement Speaker by Milton Wolf

This doesn't work with my 2008 Pontiac G8 like the vehicle match indicator said. The speaker is about half an inch smaller. I can screw this speaker into one of the mounting holes but not the other. Also, the plus and minus terminals will not work with the factory wiring. A speaker with two plus and minus poles and a wired adapter are required as factory speakers. This is the case if you intend to keep the factory connections. I gave 3 stars for both value for money and sound quality as I couldn't test them. Ease of installation is a star due to the lack of information from Revains, vehicle fitment information and the need to either cut or purchase an adapter for this speaker.
