Your cart is empty.Earthquake Sound is the original Inventor of the shallow woofer system (sws) that produces a lot of bass from a small space. Since many OEM amplifiers are now coming with a 2-ohm impedance, the 2-ohm i82SWS pair is designed to replace the BMW factory speakers that are located under the front seats Without any modification required. Simply remove the seats and replace the factory woofers with the exact-fitting sws woofers to improve the sound quality of your mobile audio. In addition to BMW cars, the sws Series are the perfect bass solution for any car. Many factories are now using woofers in small areas. To improve your bass, simply replace the factory speakers with the sws woofers.

Installed this on my bmw i4. Great quality sub. Easy install . Sounds way way better than stock . I can hear some bass in my system. I have the HK system in my car. Can't give this sub enough props!

So after one of my logic 7 subs went out and I decided to buy the dual replacement and replace both subs. The amount of bass these subs put out compared to the upgraded BMW original sound system..... Oof!!! Not even a comparison!! These sws 2ohm are worth every freaking penny!!!! The install took me about 20 minutes each side and the sound performance is just on a whole nother level. I've never heard of this brand but I'm telling you, if you're looking for a bass upgrade, this is the way to go!

This is my second set. I sent to much power in the first set and have since changed the amp they’re on. I was running 150 to each and honestly they didn’t handle that for too long. I’ve since switched over to my 55 w a channel and it’s perfect for my jeep. I’m not wanting people to hear me coming from blocks away. These fill the mid bass area quite well. Impressive sound with just 55 watts running them. Def recommend them just watch how much power you run to them.

Went with these in replacement of the more expensive "ghost woofers" and I'm glad I did. These sound way better! But what I found out the hard way is that the rings/gaskets that these come with are so weak, they broke apart both times. I need to order more of these but just haven't gotten around to it. But, if with the missing gaskets, the sound great! Get these

I have installed a lot of stereo systems, so I know a good sub when hear one, and subs this size generally dont really fulfill the role of "subwoofer" very well. These outperform any 8,10, even some 12 inch subs! The designers knew what they were doing when they came up with these. The bass is impressive, tight, controlled, and not boomy under heavy power. I definitely found every loose panel, screw, trim piece. These are worth every dime.

I have run 2 of these off a Kicker Key500.1, set gains with my Fluke DMM to 100w RMS a piece to see how they handle better power than BMW HiFi amp (40w RMS a piece). I had to basically not send any power at these at all, they start cooking pretty bad. I have headaches when I drive from the glue burning up on the voice coils. They just dont stay cool. I also run an RE Audio XXX 12" on 2000-2400w RMS in same vehicle. The SW8s were more for 60-150hz and my XXX for 25-60hz. Either way, there is no way they could ever handle 150w RMS a piece. Not happy with these at all. I will probably buy a couple Kicker 8" L7Ts and fabricate custom enclosures under the seat for them for what Im looking for, and send those an actual 500w. Read positive things, but as an installer, I have blown 2 subwoofers. 1 was over 20 years ago on my second install for a buddy in high school. The second was because a customer insisted on me using a crummy $75 used Crunch walmart amp to try and send some Planet Audio 15s 2000w (some of the worst amps in the market).If you run an unclipped signal to these, I wouldn't push em past 60w a piece, they simply cannot handle any power.They sound alright, but after 1 minute I cannot stand the voice coils burning up. These speakers are not for me.

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.

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!
