Earthquake Sound Tremor-X12D4 12-inch Dual Voice Coil Car Subwoofer, 1250 Watts

I am using 2 10's for now. These are single 4 ohm. They can take some serious punishment!!!! I am probably pushing about double the rms. I am pushing them in a simple prefab ported box.

Subwoofer in my car died about a year ago but I hadn’t had the chance of looking for a replacement till now. After doing some research, I came across this brand and turns out earthquake has been making products for years now. This subwoofer is not one of their top of the lines but after installing it in my car, it actually sounds like a very expensive subwoofer. I am very impressed with the lows and how much bass it produces. I used to like Rockford fosgate products but I am now a fan of earthquake. Do not be hesitant to buy their products since they are not really advertised as other famous brands. Do not pay a lot for Chinese crappy brands, earthquake is also made in the USA.

Great quality bass

By far the best subwoofers on the market that are budget friendly. If your considering on buying these i would not sit on them any longer. Just buy them you know you want to. Especially from Thunder AV. I ordered the dual voice coil 15s and was sent the single voice coil 15s by accident. Was brought to the sellers attention and within 24 hours i was reimbursed the difference.

WOW!!!! For the price I honestly don't think that you can beat this subwoofer. The amount of bass this thing puts out is astounding, it shakes my whole car. If you are sitting in the backseat you feel like you are receiving a massage, and are lucky if you can see straight when you finally exit the car. It can handle quite a lot of power, and I can crank it as high as I can, without blowing my Bose speakers, and hear no distortion. I am currently running a Dual DA1000D 3000 Peak Watt Mono Channel Amplifier too it, and while it seems like it needs a bit more power to truly give the Sub the power it needs it sounds excellent. I'm talking get compliments on facebook from people in my town I'm not really friends with excellent. The guy who complimented me has two Rockford Fosgate p3 fifteens, and while overall his has more bass, this single sub gives them a run for their money. I am so happy I got this sub, and will definitely be sticking with Earthquake in the future. DBXI hear i come!!!! PS be ready to invest in some Dynamat, cause if your car has any rattles you will definitely hear them. It hits!!!

I'm old school so I've always liked earthquake brand you put these in a good box they sound nice deep bass

For what I thought I was getting, buy a sub and not paying a lot if $$ for. I was very very surprised when I hooked it up. It is very loud and hits very low and deep. I added it in with 2 12s in a slot ported box that I built. Placed the db meter in 3 different places and I was very surprised when I seen the reading. Played in between 130 to 142 db. I recently took it out before I got a ticket driving in town. Lol. Sound clarity is very clear and no distortion. For the $$ it is one hell of a deal when you get it tuned right.

These subs are stupid loud! I'm not an expert installer but I know good audio and these are the best subs for the price. You can spend a lot more and get a lot less. Earthquake is the only sub I'll use. I’ve been using these things over a year now. They still slam! I’ve seen some low reviews and the main problem seems to be cheap under powered amps. These are power hungry, I have a 2500 watt earthquake amp going to two 10s and they take it all! Before buying your amp YouTube amp dyno test. Cheap amps don’t produce near the power they say.
