Actually the better dsp/amps now are 55 watts and better.
The 25 watt per channel stuff died with the ms-8 and early audison
offerings.
Almost all the main players now make a multi channel dsp amp
that has better than 55 watts per channel at 4 ohms.
Helix (audiotec fisher ) 86dsp and BMW7 models re marketed by
bimmertech and bavsound respectively . Mosconi has several
Jl audio now has them all top notch company's.

I think MusicNW probably favors the Helix or the JL versions
For speakers they use Morels on the High end for doors last time I looked
and Jehnert for the floors .
I got this setup from them with a JL XD600/6 and i still find it totaly
amazing even without DSP. No subwoofer required.

Add the OEM style sub-woofer, using the Jehnert XE200 as woofer, not sure of the crossover but I assume 80 or higher, in a 4-way, a second amp, a DSP and tuning and I am very close to your system. Also figured some sound insulation while they have the car apart wouldn't hurt.

MusicarNW told me no need for sound deadning but I put
some in the Doors anyway. The doors are already pretty beefy.

I've heard that, not sure if the E92 is the same but figured if the car is opened anyway, why not put it in. I notice the road noise, not sure how much the sound insulation will help but I will find out soon. I'm also adding some in the trunk since I usually keep the ski pass down. I need to find out why the ski bag holder has a tendency to fly out at times. I've never used it and never will so have it stored in my garage for now. I would never take my rear drive with summer tires up the mountain. I have an X6 and still use my 2000 Land Cruiser anytime there is snow.

Right now the bass from the subwoofer is a bit too much. I'm looking forward to a more balanced tuning. This from someone with an 18" subwoofer, two 15" subwoofers, a pair of 12" built in to my L/R mains and a 10" that works with my center channel in my home theater. I built the subs myself.

Had everything installed Tuesday. Bass wasn't quite right after the full-bass upgrade. It sounded a bit overbearing and muddy at times, like the bass was out of sync and needed the cabin speakers to have a bit of delay to match up. My son would probably have preferred it this way while also cranking up the JL sub remote I like to keep in the center, neutral position.

System is now tuned, balanced and natural while providing as much clean, tight bass as I would ever want. I like bass but want it reproduced close to what the artist and recording studio intended and Musicar accomplished that.

Disconnected the center channel, did a re-code from S677 HiFi system Professional DSP (Logic 7) to standard HIFI, allowing regular low level output from the head unit. Full tune and some sound deadening. Rear and rear deck speakers tuned as rear fill, canceling anything sent to both R and L speakers (I think that is how it was explained).

Excellent sounding system, made the 2 1/2 to 3 hour drive back to Seattle while listing to music seem short. Lossless iTunes files via either the iPhone 3 in snap in adapter or iPhone 11 Pro via Y-adapter sounded flawless. I haven't tried the Oppo DAC via AUX input or USB drive yet.
