Rockford Fosgate Punch 600.4

Built-in high- and low-pass crossovers provide outstanding frequency separation for great speaker efficiency. Punch Bass gives you up to 18 dB of bass boost at 45 Hz for some killer low end. And if your receiver has only one set of preamp outputs, the "4-2" switch will still let you take advantage of all four amplifier channels!

If you've got limited space in your vehicle, you can remove the endcaps to broaden your installation options.
