Speaker upgrade

I have to admit the 4 speakers on my 2017 access cab are not so bad, but I'm looking for a cheap upgrade, especially on the bass end. I have a pair of awesome Panasonic external mount car speakers. Can I just run exposed wiring from the existing rear speakers to the Panasonics and expect them to work with the fader etc.?

Or is there a product I should consider that can replace the rear speakers in the truck's enclosures and make a noticeable improvement on bass?

 

Try this thread. I just did the tweeters and the difference was incredible.
