just an update after listening to these speakers for a couple weeks.
i would unhook the 4x6 speakers and not even use them. most of them time i cant even hear them. all i can hear are the 2 4" speakers in my sound bar. I have a decent aftermarket deck with like 20-22Wrms a speaker also. It was not worth the job of dash removal for these 4x6" speakers. Additionally, these are Infinity plates at 2.5 ohm, so they should be even louder than a normal speaker. They are def not.
