Assuming that the Type R's are 15's, I would say no, the kicker won't be louder. The only way the kicker would have a chance of being louder is if you ran a lot more power to it than the two Type R's. The two 15's have more cone area than one L7 15, the only way to even a chance at surpassing it would be power, and in this case you would probably need to double the power to the L7.
