It improved the sound a lot. Added more bass to the music. Easy installation. I would recommend this speaker to anyone that has a BMW to improve the sound.

Pros: It improved the sound in the car and gave it more bass.

Cons: you have to add a separate amp to get deeper bass.

Bang for the buck

Easy plug and play install. Great bump in the mid range. Decent increase down low. It was a pricey upgrade. If I spend another $900.00 for the upgraded amp I am sure I will see even more improvement.

Pros: Easy install. Okay sound improvement.

Cons: Price. Okay sound improvement.

Huge bass upgrade

These subs are significantly more powerful than both the stock subs and the previous replacement subs I tried (Audio system AX 08 BMW 20 cm neodymium woofers for BMW). I have a 2008 3 series and am still running a JL XD600/6v1 amp that is still going strong after 10 years.

Pros: Great sound Huge punch right below the seat for a 8" sub Install is incredibly easy and all of the screws line up nicely If you are going straight from stock, the wiring harness fits easily

Cons: The previous subs I used to replace the stock subs just had wire terminals so I had cut the harness off the stock wiring. The only issue I had was finding the old wire harnesses because there isn't a easy way to wire the subs without the specific harness. This obviously isn't a big deal though.

Awesome powerful subs fit in the factory location under the seats in my E70. I use a JL600/1 amp with the Alpine PXA-H800 processor. These subs were recommended to me by You Tube channel "car audio etc."

Pros:

Cons:

These sound better than the stock subs, they hit harder and deeper and they don't hit and vibrate against the carpet and grille like my old speakers do, but if you want these subs to hit hard you need to upgrade your amp I have the JL XD600/6v2 and it's a night and day difference

Pros: Sounds and thumps awesome with amp upgrade

Cons: Sounds like stock subs with the stock amp
