good subs

I'm really happy with the subs. They fit, look and sound good. Dont quit sound like 1200 watts. But nice clean bass.

This sub pounds

I will highly recommend this subwoofer to anyone with limited space but that would want some clean deep base. I have this subwoofer in my custom wheel well box and it shakes my whole car. I have the Kenwood 1800watt amp powering it, and it love all of that power. I sounds better than my previous two 10" Earthquake subwoofer.

This is my first kicker and I must say it hits very crisp and deep for a swallow mount. I've been buying audio for 10 years and this is one if the best subs I bought . Will definitely go with kicker again

Pleasantly surprised!

Having owned lots of subs in my nearly 20 years in car audio I am very picky about the products I buy and use. If something doesn't sound good it's out. This is the first time in my life I have had the need for a shallow mount driver and over the past year I have tried a lot of different combinations in my truck. After I installed the kicker my sub bass search was done! It isn't the loudest sub I have had in my truck but it fits exactly where I need it to and blends with the rest of the system perfectly and still has a nice thump to it. I read lots of reviews where people say stuff like " it sounds good for a shallow" but this isn't that driver. It just plain sounds good period and works well in a 1 cubic foot ported enclosure with a 35 hz tuning. Sounds good enough to where I would probably use it in my next vehicle whether I need a shallow or not.

Great sub

I made a .5 cubic foot box for this sub and it sounds great! Hard to believe there is only one ten inch woofer sometimes. I would buy again.
