Subwoofers provide the most immediate improvement one can make to a car audio sound system.  OEM speakers are simply too small and not of sufficient quality to accurately produce low bass frequencies.  The addition of a quality subwoofer will prove to be a substantial improvement in your sound system.      Your choice of subwoofer is really only limited by two things:   1) the amount of space you have to donate to the subwoofer enclosure  and   2) Your budget and how LOUD you like your music      Subwoofers come in many shapes and sizes.  In most cases, one will decide if High SPL (Sound Pressure Level - An acoustic measurement of sound energy, typically expressed in dB SPL) or SQ (Sound Quality-or Musical Quality) is the most important characteristic in making that decision.       Normally, High SPL is associated with LOUD BASS.  In most cases, High-End Subwoofers will tend to offer a good balance of both SPL and SQ.  We offer dozens of other subwoofers which you can find by simply clicking on the various 'brands' on the left (also offering full descriptions), or the specific subwoofer 'sizes' shown in box above.       Dual (DVC) or Single (SVC) Voice Coil?? The primary advantage of the dual voice coil speaker is wiring flexibility. A single dual voice coil driver offers the user three hookup choices...parallel, series and independent. In a parallel hook-up the drivers impedance will be half that of each individual coil (a dual 6 ohm speaker would be a 3 ohm speaker in parallel.) A series hook-up results in twice the impedance of each single coil (a dual 6 ohm speaker results in 12 ohms if its coils are wired in series.) Finally, you can wire each voice coil to a separate channel of your amplifier, which can be useful if your amplifier is not mono-bridgeable or if you are bridging a four channel amplifier down to two channels to run your sub.   Example: Run two 4ohm DVC woofers.  Wire the individual woofers in Parallel so they each will show a 2 ohm load.  Then wire the two woofers in a Series and the amplifier will see a 4 ohm load.  Almost any amplifier can bridged mono at 4 ohms.    (*How to Wire Subwoofers-single, dual, triple, etc) (*How to choose the correct subwoofer)
