4 Channel Full-Range
For many listeners, they need only slightly higher system loudness and/or music dynamic range without the amplifier going
into distortion. By simply adding additional power to the speakers this can be achieved in many installations. BUT, the
speakers must be able to handle this additional power without damage.
Such installations are most common with listeners who only need systems that can play moderately loud. Also, this
consumer is often a person who simply cannot, or will not, accept additional amplifiers or speakers in the vehicle. Such
systems will not be able to perform as well as audio systems with additional speakers and amps, but this is often an
accepted trade-off for this consumers.

4 Channel Combo (2ch HP + 2ch Full-range)
Like the four channel systems as shown above, the benefits, and performance trade-offs are similar. But, this system
configuration offers an additional advantage with the internal high-pass crossover.
This crossover reduces the bass to the front speakers thus protecting them under heavy low frequency loads. A typical
system with larger drivers in the back is then able to be pushed harder without worry over the power handling on the front
speakers.
