If you're in the market for great subwoofers at a price you can't beat, take a look at the Kenwood KFC-W3012 component car subwoofer driver. The KFC-W3012 has been redesigned to out perform it's predecessor to last year’s KFC-W3011.

I have these in a ported box tuned to 38hz with an internal volume of 2.01 cubic feet. They’re mounted inward on top of the box so everyone can see the magnets, with the ports pointing towards the back. I built the box myself for my '00 Montero Sport, separate chambers with cross bracing and double sheet baffle of 3/4inch MDF. Right now I'm still breaking them in pushing only 120watts to each speaker. After break-in period of 50hrs, I will bridge my amps. Using Blaupunkt PCA2120 amps, 1 per sub, 300watts RMS w/350 max dynamic.

This is the 2009 version of the 3011's with improved cone designs. Thanks for free upgrade OCS... I'm not going to tell you these are the best subs in the world because they aren't, but I will tell you they are amazing for the price. They are very fast and pick up a good range. They hit very hard. When I first wired these baby's up I was very surprised. I am more than happy with them. These can blow away many sub-woofers that cost double the price. If you just want some good loud base for a cheap price this is the perfect sub for you. Also OCS's price was very good. At my local electronics store these subs retail for $140.00 plus tax.
