## Description

You've been asking and Earthquake Sound has been listening. The tremor-x subwoofers are now made with Dual coil by popular demand. These tremor-x's are built with tct technology which allows the driver to play louder longer by keeping the voice coil running cool at all times. They also have stitched leads, reinforced dust cap construction for linear movement, and bigger, more effective magnets with added cooling devices to increase efficiency even more. The tremor-x subwoofers have No equal and are ready to prove it.

Review: Great budget sub!!! - 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.
Review: Bass shaker - 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.
