do a search, or even look up the stickies in the subwoofer section. they are probably consolidated at the top of the thread group

ported box couples the back wave with the front wave adding dbs. depending ur boxes tunning it can be 3dbs louder at certain frequencys. 3dbs = to doubling ur output.

:confused:

3dbs is the equivalent of double power, not double output. Aroundish 10dbs is double "output" to the ear.

and yeah there's usually a big difference. But ported box need more space and aren't for every single subs
what's your plans?

No, 3 dB is double the sound intensity in the world of logarithms. 10 dB is 10 times the sound intensity. What is the definition and what is to the ear are different stories.

ok just to clear what I was trying to say, which one would be better the get, or does it just depend on the subs and the vechicle

That's completely dependent on the subs, your preferences, your power, and the space you have to work with.

depends on the sub, depends on the box builder, depends on the vehicle, depends on equipment install, and when you want to build really specific it depends on music genre preference.

the subs are two 15" kicker cvr's
don't know what the box builder is, it's a ported box
the vechile is a trail blazer
The equipment install should be fine, it was originally installed for a memphis mojo
and the music, I like listening to is rock and rap
