My front setup is unconventional, I have Dayton 5.25 woofers in the stock dash locations, with the mounting surface sealed, and A-pillar Tangband mini full range speakers, and mine is at least as loud if not louder as any coaxial setup regardless of "rated" sensitivity, and sounds great (for being in a TJ with bad speaker locations) to boot. My dash woofers sensitivity rating is about 84db, and my A-pillar speakers of around 80db. I only run a 45w x 4 Kicker Key amp, bi-amped to those front speakers.
If say a Polk coaxial's sensitivity was truly 10-12db higher, I'd need about 500 watts per speaker to be as loud, which of course the speakers couldn't handle, in addition to having power compression way before even 100 watts of power.
I know that the Polks and sensitivity ratings get thrown around as absolute fact and necessary, but my actual experience and proof says otherwise.
This is loud enough to over load the phones mic at times, and I had to keep the volume low enough to record it. You'd need to yell over it if two people were up front while running at maximum undistorted output. This again is 45w x 4, and speakers with very low rated sensitivity. There is a powered sub mounted to the tailgate going too.
The video is with the top and windows down. Don't use a phone or shitty speakers to judge it.
