Fits BMW G30
Fits BMW G30, I couldnt find any information on it online but to share my experience, it fits perfectly just need to trim a bit of foam off, i just plucked it off easily, oem grille cover fits over it perfectly and the sound is 100% worth it, way better than OEM

Pure thumping bliss
I paired these up with the JL Audio xd600/6 crossed at 120 hz and it is pure audio bliss. The bass is thick and rich. Is not club style throbbing bass for EDM, but for rock, funk, disco, soul, it is excellent— tight, articulate and powerful. Everybody who I demonstrate my car audio comments on how clear and tight it sounds and I get immense enjoyment from listening to it every day. The only thing to be aware of is that as other people have commented, you need to be prepared to creatively make the area on top of the subwoofer provide an inch or so more clearance for the subwoofer to move back-and-forth without hitting the grill. I accomplished this by putting a piece of wood as a spacer on the two sides of each subwoofer and then getting extra long 2 inch screws to screw the grill back in. It is completely not noticeable after closing everything up because this area ends up being entirely under the seat.

Finally my F34 sounds good
Simply replacing the stock subs in a Hi-Fi system makes a huge difference. Now subbas is present even without adjustments in bass menu. Finally I'm enjoying my car's sound!

work great with factory hifi amp and easy to install
Subs overall sound great with the HiFi system in my 328i how ever the push terminals are trash. very loose and causes the sub to cut in and out. hoping the company will send me out a new frame with terminals

Adapter Rings
The rings that come with it are made of cheap fiberboard and break really easily. What a waste of time

Recommended for those with a BMW
"Almost" a drop-in sub for my BMW. Just had to shave a few items down in order for them to fit. Simple enough though. No real cutting or drilling to make these work. Good Stuff!

Must be in enclosure
I have the 8s and sound good sealed up. These are not for free air although shallow. Its free ship back if you dont like them. They are not as good as qual as for example kicker. I put the kickers back in my door after trying these and lack power handling however the 8s are just better.
