Welcome back! First of all, your lights look dope (if those are indeed yours)
Yeah no one likes screeching blower motors although most of us have had to deal with them (I still Do!) but your new audio components sound like they'll be much better! That 10" will pack out your e30 no problem -- I love my energy stuff it's real quality and amazing sound. I use energy stuff in both my e30 and e46.
Good luck on all to come! Suspensions next then?
