Great bass for the price. Hits lows pretty well, and definitely bumps. If you are looking for an improvement in car audio, I'd recommend this sub. But, in my opinion, it's really all about the amp that you use to power it and the box that you use to house it. Overall, great woofer for the price.

This is a great buy, I use it in a single woofer application in an enclosed box.... Hits hard sounds awesome!! I would recommend this product.

I recommend these subs to anyone who is looking for a good clean sound. I have two of these in a ported box on a MB quart onx.1000D in my maxima and they slam. Good lows and mid bass response.

I bought these because of the price they were $49.99 when I got them so really couldn’t go wrong…I am running them with a Hifonics Colossus at 600 watts rms a piece they seem to be holding up good and sound very good hitting low notes very well with good sound quality…I have always had name brands like Kicker and Alpine and these sound every bit as good to me I plan on putting 6 in my Excursion if these hold up so yes I am beating on them and will update my review in a month or two. I gave low scores on features and ease of use because of being only a single 4 ohm VC

These Earthquakes are the first subwoofer i have ever owned. I am happy with the sound the bass hit really hard an smooth in a close box will buy earthuake sub again if these hold up. Only had 2 months and they hit.
