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.
Agreed - if you cross the sub over low enough.
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 keep talking about bandpass speakers this way, which forces me to
mention that some bandpass alignments are very dependent on a good
electrical low pass filter, because the FR of the port's output is very
rough in the upper bass and/or lower midrange.
You probably picked an alignment with well-controlled port radiation - mazel
tov!
