How to Install DVC Subwoofers in a Car
DVC (dual voice coil) subwoofers are the most versatile subwoofers on the market and are available through many car audio suppliers. While usually more expensive, DVC subwoofers allow more flexibility to car stereo enthusiasts. For those looking to maximize the output for a single DVC subwoofer, the option of wiring it using a parallel circuit works best. Mounting two or more subwoofers requires a series connection, also available with a DVC subwoofer. You can have a technician mount your DVC subwoofers, or you can do it yourself and save the cost of labor.

Tips & Warnings
The difference between series and parallel has to do with impedance levels (measured in ohms). When connecting two impedance levels to an amplifier in parallel, the ohms value is halved. In series, the ohms are doubled. Check to see which would fit into the accepted range of your amplifier.
If you place a load on your amplifier outside of its safe accepted level, the amplifier will overheat and quit working. This may cause irreparable damage to the amplifier.
