Even though the rear deck has tweets and Mids and the rear doors only have mids? I have not changed the under seat subs yet and have not decided on the trunk sub yet. May do the JL Stealth box unless you feel what you used might be superior?
This is an E92 M3 (Coupe).

Your Dirac (EPS) OEM system has coaxials in the rear doors and components at the rear shelf. You swapped the OEM EPS system speakers with the BSW Logic7 sytem replacement speakers. Thus no coaxials anywhere.

IMO, there is no audio quality reason for swapping the OEM EPS speakers with the BSW Logic7 speakers.

I think that the MusicarNW sub box is a much better sub implementation in our cars -sound quality, fit and utility- than the JL Audio Stealthbox. One thing for sure, the Stealthbox blocks the folding rear seats.

Do you have back up sensors and GPS? I have been struggling with how to interface a system and cant decide between the Alpine you are using vs Mobridge. The iPod interface under the middle arm rest is god awful and if I use one of the extra digital inputs on the Alpine for my iPod then I loose GPS and backup sensor voicing. I have a way to pull digital from an iPod/iPhone and still send USB data for controls through the stock system. As this will be my primary source. With Mobridge there is only one digital input unless I splurge for the iPod interface too. But the price of doing Mobridge and DSP etc etc will be so much higher than the Alpine.
You should search a little bit more about the actual details of your EPS system and the differences between EPS and the other OEM systems (Logic7/Harman Kardon and HiFi). I have posted at least 2 full upgrade/decoding threads on the EPS system. The H800 cannot be installed in a EPS system by itself. This thread is not about an EPS system and the H800, this is a HiFi system integration.
