If you skip the pods, please make sure you get boom mats behind the speakers. The pods will allow for better sound, only if you use polyfill inside to tune them with a decent speaker. Speaker sensitivity match is more important than anything else.
I chose speakers with a lower sensitivity and opted for no pods, but have boom mats behind the speakers do that the sound is not "lost" behind the dash. Sort of speak. I can tell the difference with some music types with or without the boom mat, which is why i chose to keep it. In my JKU I polyfilled the speaker pods and upgraded the factory speakers to better more sensitive ones and that made a night and day difference, even with the stock unit. I didn't even touch the tweeters.
