Summary: I love the sound of this sub until 2 1/2 months later after installation I notice something was blowing my fuses, I check all the wiring of the installation and I even bought an other amp thinking the one I have was the trouble, and after installing the new amp what a surprise the sub still not picking up so I ask my friend to let me borrow hes sub and everything works perfectly. So disappointing of that product.
Summary: First off, they sound great! Made in vietnam, slight plastic excess drip on the one i got. I'd recommend it for people who just want a decent amount of bass, that will shake the rearview mirror of my Buick Le sabre, trunk rattles, but no flex because its metal, and not enough power running to it to cause flexage.
Pros: 4 ohms, 250 rms, 1000 W max, free shipping, awesome back massage in my car!
Cons: All depends on how you power it, and what quality audio imput you have
