what would give me the most spl?

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.

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.

yeah the car is also a variable, but in a controlled environment where the only variable is the number/size of subs in properly built boxes the 3 15"s should take the lead in my opinion. Of course it's going to take more to get loud in a van compared to a CRX.

that of course would be the biggest variable

This thread.... just saddens me... at least the OP learned the errors of his ways.

at least they did not destroy the vehicle while learning.

to get the spl you refer to on a single 8" is an achievement in it's self. Not to take away from that challenge, but personally, I love the sound reproduction of a 15" subwoofer...in multiples...
