I have the Dynavin E39 D99+ as well and installed it myself in my 4.8is. I had DSP and ended up running RCA's from the headunit to the rear. Bought an 800 watt amp and deleted the DSP amp, bluetooth and CD changer. Had to include 2 adjustabole noise reducers for the alternator whine. Those are in behind and below the head unit. Modifying the space for the new frame was ok but, do take your time on it.

All in all the Dynavin works great and got an Infinity basslink subwoofer to help with the thump, I wanted!

Good Luck!
