Plenty of speakers fit the dash without trimming or re-shaping the duct work.
Blam lfr-52 is a common one I do if the mid-bass can meet it around 500hz. If I use a midbass that struggles past 350, I'll use a 3" (80mm)
But it's not informative if you're leaving out key details to save the end user money, time and hassle.
There is ZERO need for an LCi product in these trucks.
Putting a full range speaker in the lower door of an OEM 2 way system is COUNTER productive and more expensive.
Investing money in...
I did. You're in transit shots show an LCI and an amp that's capable of hi-level and low-level.
Zero need for the lci.
You still don't need full range speakers in your doors. You show 3way JL 6x9s.
You still could invest your rear door speaker budget into the front stage or a better amp/dsp...
You don't want full range speakers in the front doors.
You don't need a LOC. Use forscan to convert output signal to low level or use the amps hi level ins.
Skip the expensive rear door speakers and focus on the front stage and amp.
Use the saved money and leave oem rears entirely oem and...

Final rta on right screen. Before minimal salt and pepper by ear changes.
So Scott reached out and gave me an initial budget to which we spec'd a 2way active front rear and single slim 10 behind the seat, with Match amplifiers.
The limitations were definitely going to be the single sealed 10...

You'd be surprised how much resonance can be absorbed from the outter door skin.
I use resonix guardian on the outters, resonix cld on the inner and door card with some butyl rope if budget allows.
If a tight budget, it's guardian on the inner and soundskins on the outter and speaker rings.
