Everyone in the car audio world wants a good amount of power without have to break the bank. With the Earthquake Sound DB12 400W RMS subwoofer you can get just that. This woofer is all about business and on delivering the best performance possible at a fraction of the cost. The woofer features a high strength sand-blasted woofer cone and santroprene high-roll surround for enhanced strength, longevity and performance. High current stitched tinsel leads and a Turbo Prop cooling system allow the woofer to play louder and longer by effectively keeping the voice coil at a cooler level.

It's not easy trying to find a high quality woofer with a decent amount of bass output without having to cough-up at least 100 dollars, but with the DB12 you can achieve great bass reproduction without having to break the bank.

I bought this sub with an absolute box from my friend who fried his amp and i have it hooked up to a kicker impulse 652xi stereo amplifier which only puts out 190 RMS at 2ohms and it hits harder than i thought it would. Its not the bass i want cause i like heavy loud bass but this sub would be good for people who dont want to cause alot of problems between the neighbors. Good starter sub.

These subs are unbelievable. I thought the 19mm of xmax was complete bull until i actually got this thing hooked up. WOW, am I impressed. This sub is unbelievably, clear, accurate, and it POUNDS harder than any 400w sub i have ever seen. And a 5-Year warranty? that's insane! I dare you to put this thing up to any other 400w sub out there, it will DESTROY.
