don't know about the box, the type r is a good speaker though i guess. I would recommend some other brand though just because i personally know so many people with them (they're still a good value nonetheless)
the type r's do have way better sq than my l5's but my l5's get louder for sure. If you don't want THAT much bass though one should be ok especially in a truck. one of my friends just had 1 12" R in a SEDAN and it hit pretty good
