Default Advice on my frontstage.. sounds harsh turned up? Ear fatigue?

Okay so I have a 3-way cdt passive setup in my 06 mustang gt.

ES-010 Tweeter
HD-4 Mids
M6 Midbass
ES-300CC Xover
Soundstream 150x4 (ish) Amp

The tweeters/mids are in kickpods on the floor and the midbass is up in the stock door locations.
I notice that when I turn up the volume more than half way, it seems like the highs are harsh, or rather certain letters in vocals and especially guitars ring louder and actually hurt my ears almost. I noticed Eqing down a bit in the 1-2k range seemed to help slightly, but now it sounds a little muffled. Certain genre seems worse than others.

I'm also considering buying some new door panels that have a spot for an 8 inch woofer in the doors which would allow me to go with a 6x8 coaxial setup above in the door and a larger more powerful 8inch midbass lower in the door. I'd really like to feel the kickdrums with authority.

Any advice here? I have my headunit on full pass through as well as the amp full passthrough to the passive crossovers. I was thinking of putting a different amp I have on it when I get home to see if it affects the sound at all, and that would point to my amp.

Clipping in the amplifier will definitely cause the problems you were hearing. You need to run a high pass filter so the midbass drivers aren't trying to play all the way down. That won't explain the harsh midrange and treble, but it will help those speakers last longer.

Try going active? Sounds like a great setup with midbass midrange and tweet (what I wanna do someday). You should look into maybe a hu that has crossovers time alighnment eq and stuff. You could then adjust the levels of each speaker induvidualy and crossver points. Are you running a sub stage? And how is your speakers wired to amp? Like what speaker to what channel?

Ive considered active but seems like a lot of work. My amp just has two channels that go to the crossovers and they split everything up. Right now my substage is out as I'm trying to downsize and I'm considering putting two 8's in the doors or doing something small custom in the back. I need my trunk and backseat.

Get an EQ. (assuming it hasn't already been suggested)

Haha oh sorry, no its 2 of each, the soundstream amp was a 4 channel but I just was not using the other two channels, just 1 and 2. I just plugged in a Jl 300/2 in its place (150x2) and it sounds better already, still needs some EQ.

Speaking of EQ - I take it then the basic EQ in my headunit probably isnt good enough?

Oh ok well what headunit you got? And you could have split up the speakers between the front and rear chanels of the 4 channel to use the amps crossovers induvidually and control the levels simply using your fader from front to rear

Fatigue can totally be caused by distortion/clipping. It may actually sound pleasant at first, but then it starts to sound like shit. Fatigue can be caused by deflection too, but since your tweets are in the kick, that should be a non issue.

The harshness on certain letters of vocals is known as "sibilance." It's especially noticeable on sounds like "ess" and "shh". Like the singer is standing too close to the mic. You can usually fix that with some EQ cut at 6-8khz.

The cut at 1-2khz you made may have seemed like it helped because our hearing is especially sensitive to 2khz and it's the most noticeable EQ band to adjust. So, it probably just seemed "less loud" to you.

My advice ois to get some more EQ stat. Or at the very least... do your crossovers have any attenuation for the tweeters? I've heard that CDT's are pretty bright.
