Now that's one sweet sales page. Not crazy about some of the design elements, but it's a simple explanation of what the system does. Components look to be at least reasonable quality wise, though I'm sure the aftermarket could provide a step up for those who require it (not me). Love that it's a full 8" subwoofer, and not an overstressed 6.5" unit. Plastic sub boxes tend to resonate, but I bet they solved that in the design, so no worries there.
The amp will run hot - 506 watts at 2 ohms...nice numbers and completely usable, but they don't provide THD (total harmonic distortion) numbers, to explain if what you'll be hearing will actually sound good, r will high become clipped and lows muddy. You don't need a lot of power to drive clean, crisp, even loud sound levels, so hopefully the amp is actually a 4 ohm unit, stable at 2 ohms where the big power numbers can come out to play for marketing purposes. Even 100 watts at 4 ohms would be plenty in a truck cab.
Great find!
