Speakers

Just replace them with a nice pair of alpine type R 6x9's even if they are 4 ohm it should work just fine. it would only be quieter because the factory amp is likely tuned to run at that impedance. if its not very loud just run an aftermarket amp it'll sound way better than stock anyway.

You will notice to major difference when you replace your factory 2 ohm speakers with aftermarket 4 ohm speakers:
Better SQ but less volume.
You can fix that though by upgrading your head unit to aftermarket too. Or just get 2 ohm speakers. But I promise you will be much happier with aftermarket deck and speakers than you would stock deck and aftermarket speakers, no matter what impedance they are.
