its awesome

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!!!

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 purchased 2 of these earthquakes in 15's and installed them in my grand prix with a 800 watt amp and makes my cars body flex like their no tomorrow....these are extremely loud and hit very very very low ....it is the best subs I have ever owned in my life ....you won't be disappointed

Amazing bass high quality !!!
