The SWS-8X by Earthquake Sound features a mounting depth of 2-1/8". With a depth this small the applications for this woofer are endless. This shallow-woofer-system series subwoofer is perfect for those with limited space but that still want some bass in their car. This woofer is also the perfect replacement for factory upgraded systems, especially BMW vehicles. The woofer features a light weight resistant PVC cone and a long-lasting UV treated high-roll composite foam surround for added rigidity, stiffness, longevity and increase power output and performance. Don't let the size of the woofer fool you into thinking it's not powerful, with an Xmax linear excursion of 23mm this woofer will hit low-frequencies with accuracy and precision for a clean, crisp, and responsive bass reproduction. Although often imitated the SWS's 3 protected U.S patents assure that it's never duplicated. If you have 2.5" of space to spare then there is no other option than the SWS series subwoofer.
Where Should I Install the SWS Subwoofer?
Earthquake SWS subwoofers are designed to be installed in areas with limited space. This makes them ideal for truck cabs and under seats. As noted in the diagram below, these subwoofers are perfect for installing underneath the front seats, under the rear seats, or behind the rear seats.

Excellent Speaker
Very tough and good sounding. Sounds bigger than it looks.

Best product for your BMW
Fits nicely in stock box, use JTSherri spacers (find him on BMW forums) to avoid having to make your own. If you properly seal the subwoofer to the box, the sound is very refreshing up from either Logic7/HK or Premium HiFi (M3). No more muddy bass plateau. Use a good amp to drive it, do not attempt to use the stock BMW amp.
I bought an Alpine PDX-F4 on this site as well along with a BMW specific harness (look again in BMW forums) for an easy install and am 100% satisfied.

Good!
I bought this for my F30. Worked well and I think it's a pretty good choice for someone not satisfied with genuine subwoofer.

Good sound but....
For the normal listener, these speakers are great. Really, really better than they appear. Nice warm sound with a lot more punch than expected. They fit perfectly into my BMW 335. Those of you looking to help out the piss-poor factory BMW stereo, these speakers are for you. You will not believe the difference in sound quality. These speakers are a pleasant surprise.
I, however, am not the normal listener and melted mine in 6 months. I was running them with a 360 and two Arc Audio KS 900 amps bridged.
Again, for the normal listener, these are great. I am sad that I melted them because they sounded so great (just a little too weak for my bleeding ears).

Pretty impressive
Pretty amazing speaker. Good to fill in the gap between your components and sub. I have a Toyota 4runner and have 2 installed in the back panels and work real well for a mid-bass speaker.

Wonderful Product
I used a pair of these ground shakers in my BMW 5 series, f10 powered with NVX MPV1 monoblock amplifier. Unbelievable result. I dont need an extra subwoofer in the trunk. My car seems totally standard until I turn the volume on. Congrads Earthquake

They work good!
I used these to replace my logic 7 woofers in my 03 745. there was some mods needed to keep the factory speaker connector but overall pretty good and im powering them off the stock logic 7 amp. They aren't as good as the factory logic 7's but for $150 or whatever this cant be beat I highly recommend these.

Not Impressed
I bought this sub to add a little sound in my pickup, since I use it as a work truck I needed something small that wouldnt take up much space. I made a box to the specs and installed and was not impressed at all!!! The dustcap makes a horrible racket so bad to the point that I took it out, now im stuck with a $170 paper weight not happy at all dont waste your money!

Compact and easy to install
This is a great compact subwoofer that can be used as a replacement of the BMW under the seat woofer. It is a direct replacement if you can get the spacers. But the Earthquake is the only choice as a direct replacement and there is no other choice in the market.
