I don't drive too much solo with the whole CoronaV thing and no work commute.
A couple years ago the Mark Levinson amplifier failed, and I flailed around homebrewing a solution to replace the 12 channels of dsp and amplification (documented earlier in this build thread). Ended up with 7 channels on discrete micro amps (Front bass, front mid/tweet, rear bass, center) around 75W each channel, 4 channels on the small dsp amp (rear mid/tweet, rear hatch) and 200wrms on a micro amp into an updated 10" subwoofer. Aside from the subwoofer these are all stock speakers. It all runs thru a 12 channel DSP. I recently put in a couple hours fiddling with the tune to flatten out the response and cool down the subwoofer a bit. I haven't really spent any time listening to it at volume, as I am typically road-tripping with the family.
I had an in-town errand to run (20 min each way) and thought I might as well run a bit of volume while at it.
For background, a typical freeway, kids in car, reasonable level is 22 or 24. 60 is the max.
I cranked it on up to 45 and tooled on out.












Clearly I need to spend more time driving aimlessly around . . .
Clear, perfectly imaged sound with no distortion anywhere. Sounded better than I could have dreamed. Mirror shaking amplitude but no listening fatigue. Hard to describe, but so loud you don't want it any louder, full spectrum sound and feel (low bass extension) but all in the right place and volume balance.
I know it's not a common mod in the 200, but improving the sound system is worth it folks.
