Did you use the average readings (tracks 1 & 2) of 40hz and 1khz off the factory amp? 16 seems very low. I hope it doesn't clip at 16.
You may also want to lower the EQ on the head unit while you perform these tests. Go below flat, see if that helps.
Do you have an RTA? you can check the signal while you adjust the factory EQ.
