I had the infinity kappas in my old Sierra that had the bose, they are a 2ohm speaker. They sounded great with an aftermarket headunit, super loud and clear. When I put the stock headunit back in for various reasons ( when first one was stolen, when i traded in truck ) they sounded even better with the factory one. Sounded just as good as my aftermarket with a 10" sub. I know infinity isnt the most expensive or probably even the best anymore but I certainly liked them
