Even then its a complete unknown. A 4 door tundra will not do well on the meter compared to say, a small hatchback. So yes, with similar tuning it is very possible to get a single 8"(especially a SA8v2) to meter louder than 3 15's. Even with really good equipment the op only scored 144db in that truck, my single 8" is very close to that, but in a small wagon.oh I see what you did there... I meant more of an even comparison, both ported, same tuning, enough volume for their surface area etc.
