The Monsoon system has an amp/subwoofer in the rear, on the left side. If your GF's truck has two storage compartments back there (one on each side), she doesn't have Monsoon. If there is storage on right and speaker on left, it is Monsoon.
And, by the way, nice choice of girlfriend.

Just wondering, what nav unit did u install ? I just got an avic f700bt installed and originally my volume was very low and I thought the same. But after some adjustments the sound is now better then with the monsoon, crispier.
