well i plan on building a ported box in the trunk of my civic. it will be facing foward and i will attempt to seal the cabin from the trunk in the process. well this is a design i came up with(foot = inches)
i beleive the total air space is about 7cu after displacment and the tuning is at 30-31hz.
it is pretty much the max dimensions i can use w/o making an odd shaped box in the trunk.
question: would this be ok for 2 xxx15's or should i go bigger?
are my port calculations off?
should i squeeze out another cube of air space?
