SO now we have this playing, and cannot believe the output from the 3) 6.5" subwoofers, tuned very low, in a configuration not at all setup for numbers is blowing our minds here. We knew it was going to sound nice but this exceeded what we were expecting output wise at such low frequencies.
Lets put this on the meter and see how it performs in the large vehicle.
Again, this is not an SPL configuration, and not a car to go for numbers in.
The real fun part about this is we are peaking at 33hz, keeping in mind, 3) 6.5" subwoofers total cone area is less than a single 12, and slightly more cone area than a single 10"
Below is our first go at metering this vehicle.
