I have a 2011 328xi with the HiFi sound system and noticed that the mid-range door speakers are starting to distort even at moderate volumes. Does anyone know of reasonably priced replacements (non-OEM) that will fit in that hole and provide better sound quality? I'm looking in the $100-$200 range if possible.

Any 4" speaker with an installation depth smaller 45mm should do.
I had the standard sound System and upgraded to the Alpine SPG 10c2.

The difference is very noticable, but the standard sound system is also really bad.

BMW uses a 3 point Mount System, so you might need to get adapters, I printed those myself, there are some templates for those.

There is and entire e90 stereo sub forum here.
The amp is very weak in the Hi Fi system and the speakers
are cheap . It falls right apart when you turn it up.
The greatest improvement comes with and aftermarket amp
but the speakers are still crappy compared to aftermarkets.

The logic 7 4" speakers are probably your best bet.
