Earthquake Sound Sws-6.5X 6.5-Inch Shallow Woofer System Subwoofers, 4-Ohm (Pair)

Huge improvement over the base system woofers & amp of my F30 335i. installation is smooth.

Great sound.

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 . Dont buy it .

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.

So happy to have made the upgrade, now i can finally feel the bass in my seat. Most definitely worth it.

These subs are a significant upgrade to replace the mediocre factory woofers. They install easily and sound amazing. I have mine powered by a 5 channel amp driving 300watts rms to the two woofers. I couldn’t be happier. Do they hit deep like a 10 or a 12” sub in your trunk? No. But they round off the sound of your stereo and add a nice kick to your music that will leave you and others impressed. Word of caution, they do have quite the excursion when compared to the factory woofer, so you may have to leave off the speaker cover and trim some of your carpet as I did in my e90 335d. Do I recommend these? Would I do it again? In a heartbeat. Cheers.

Bought 2 pairs and each pair had one with a defective voice coil which rubbed internally creating an undesirable rattling sound. One of them even had a dent in the aluminium frame. On the upside, if you're lucky enough to get 2 good ones, they'll sound amazing!

Installed on BMW E90 base audio system, great bass, so happy!
