Polk Audio's db Series car audio subwoofers have been a big hit since they were added to our product line-up and it's no surprise! The db series subs are the perfect balance of cost and quality and feature single and dual voice coil version in 8", 10" and 12" sizes. 

• Single and Dual Voice Coil subwoofers are optimized for high performance in virtually any enclosure type: sealed, vented and band pass.
• Wrap-around Rubber Gasket seals the sub in your enclosure for airtight performance.
• State-of-the-art laser-based Klippel measurement technology perfectly centers the subwoofer's voice coil in the magnetic field, improving X-max and BL linearity, and the sub's micro and macro dynamics, for deep, precise, bass!
• Black Matt-finish Composite Cones are unbelievably stiff for real gut-pounding bass.
• Injection molded ABS dust cap also stiffens the cone to suppress unwanted resonance for incredible low distortion, high impact bass response.
• Big beefy magnet structure and motor assembly for high output bass with tight control.
• Durable Butyl Rubber Surround for consistent, reliable performance.
• Four-layer vented voice coil runs cool while your music stays hot.
• Vented pole piece for higher efficiency and ultra-high power handling.

Pioneer TS-SW2501S4 & TS-SW3001S4 Shallow Mount Car Subwoofers

These shallow subwoofers from Pioneer Electronics require have a mere 3" to 3-1/4" mounting depth and are designed to perform with as little as 0.5cu. ft. of air space. Many would assume that these car audio/stereo subwoofers don't perform as well as a standard subwoofer simply because of the size, but if you're willing to give them a try; you're in for a big surprise.

The TS-SW2501S4 (10 inch) and TS-SW3001S4 (12 inch) subwoofer feature Pioneer's patented Air Suspension Control System which provides extremely precise bass response. In addition the cones feel extremely sturdy due to the basalt/carbon fiber reinforced IMPP used in it's construction.

This just in: 

We've added a couple of entry level subwoofer models from two of your favorite car audio brands.

First up we've got the super affordable Kenwood KFC-W2512 10" 1000W Component Car Subwoofer Driver.

This car audio subwoofer features a single 4-Ohm voice coil and is rated for 300W continuous power.

Don't let the price fool you, Kenwood put a lot of resources into re-designing this line from the ground up and it really shows in performance. Take a look at what people have to say about the about the 12" model (KFC-W3012).

Next up:

We've got the JL Audio 15W0V2 15" 500W Component Car Subwoofer Driver. 

We've just added the Boston Acoustics G3 Series Car Subwoofer Drivers to our product line-up.
All models are in stock and ready to ship.

Each driver features

• 2-3/4 inches of peak-to-peak excursion
• 2-1/2" 4-layer voice-coil
• Radialvent cooling, for increased power handling
• SureSet impedance selection and overdrive protection
• Multiple enclosures types and tuning options available
• Integral sealing gaskets simplify both standard and inverted mounting

KFC-W3012

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.
