swapping stock speakers recommendations

[UofM21]

I would like to swap out the stock speakers in my 230. I was hoping to get a bit better sound. I would also like something that is drop on for the locations. I want to do all 6 6.5 speakers and swap the sub for another that would bolt into the same location with no mods. Thanks in advance for the help.

I opted for the JL 6.5's in my boat with the JL 250w infinite baffle sub. Earmark audio has some pretty good deals on them and you can use your PN 10% discount. Speakers dropped right into factory locations and they all sound awesome. That IB sub is amazing compared to factory Polk.
