Review: Better than you'd think - Huge improvement over the base system woofers & amp of my F30 335i. installation is smooth.
Review: Amazing Shallow Sub - I bought these to replace my blown CX5 speakers. They are not quiet a perfect fit but with some adjustments I made them fit. Amazing sound and so glad I could get them in a 2ohm variant. Great price considering the factory replacements were double the price for one. So happy with the purchase.

## Questions & Answers

**Q: How do they sound in a door?**
A: I have a 96 s10 and the hardware in my door rattles with it installed. 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

### ⭐⭐⭐⭐⭐ Better than you'd think

### ⭐⭐⭐⭐⭐ Amazing Shallow Sub
*by J***N on 18 November 2022*

### ⭐⭐⭐⭐⭐ Amazing for my BMW F30
*by P***K on 14 November 2022*

Replaced a pair of Jehnert speakers with these and must say they are much better for my taste in music. If you like low end bass then these are for you, this is exactly what the Jehnerts lacked for me. I drive these at full power from an external amp and they’re great, but make sure you have an amp powerful enough to do so otherwise they may not be as loud as you’d like. Quality is great, the adapter rings having a foam surface is a nice touch also and the speaker wire pass through terminals is really helpful.
