So, in my experience, they sound terrible in the doors. I did put them in a box and they sound amazing for a pair of 6.5s **Q: Will this fit under seat in F32 BMW 4 Series? The Bavarian Motors for a one is like $300 this is a third of the price if it's better than the stock on** A: Yes, and they are the best replacement subs as long as you also upgrade the amp to the match up7bmw. They are good on factory amp but with the increased power, they are stellar.I had mine running 24hz to 86 hz with 30 db/octave high pass and 24 db/octave low pass xovers on the match 7. Absolutely accurate, no cone distortion, just absolutely transparent and unlocalizable bass. **Q: are these a single 2 ohm voice coil** A: Hi I purchased the pair of sws 6.5x which are single 4 ohms coil the sws 8.are also has a single voice coil, but at 2 ohms each. You can double check at amazons web site. Worth the upgrade if you really like to feel the music. **Q: Will these fit my 2013 bmw 750i xdrive?** A: all the BMW sub is 8ich ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great. *by on Reviewed in the United Arab Emirates 18 February 2023* Great sound. ### ⭐ Not suggesting *by on Reviewed in the United Arab Emirates 27 April 2024* I m not suggesting due name is earthquack but when is use in my honda civic , audio is normal but when its comes bass and quality , audio is worse .
