My 16 yr old daughter bought an Insignia IS-PCSS101-Two
12" 8 Ohm speakers and amp, 200 Watts into 4 ohms. This
is a subwoofer system. Dad's job- Get the most thump
from what she's got. I will build a cabinet for the
trunk.

I tried putting subs in the trunk, once. I was not
pleased with the coloration that resulted from shooting
the sound through the back seats.

That's often a pretty effective low-pass filter.

One friend of mine cut out the back of the well the rear arm rest folded
into. You just popped it down for critical listening. ;-)

If the sub is only low bass, there should be no coloration except for possible resonance
effects. I built one system with a bandpass, with the port entering the passenger
compartment with the box in the trunk. That gets rid of any possible effect. You
can also use that on ported boxes, if the bass is limited in range.
