Blaupunkt ODw1000HP - these have been in my car and I had another set in a friends car both sets installed IB. These subs got nice and low, where they lacked was the ability to handle power although they did better with my setup than my buddies. These subs really hit, they tackled the low end blending with my Dyn MW170's no problem and they kept up very well. Very impressed for shallow mounts.
Power handling: 6
