The biggest punches sometimes come in the smallest containers. One example is the Alpine PDX-4.100. This small yet powerful 4 channel car amplifier packs a full 100 watts to each channel. It uses ultra efficient Class-D technology to make sure the amplifier works great but stays cool. This runs so cool that multiple units can be stacked on top of each other for a multi-amp setup.
