I'm going with 2 of these in the trunk of my Camaro
They are 12" subs with tuned passive radiators...each one puts out the power and db of a 15" sub. Two of these babies is going to be just ridiculous. I'll have 400 watts RMS per sub going to them for now and if that's not enough I'll upgrade.
I figure these are perfect for the Camaro considering the small trunk opening. I'll put one in at a time and position them in the best sounding spot.
