The sealed enclosure should be tuned low and the port area should be tuned high, right?
You want your front enclosure to be tuned to the FC of your sealed box.

I was reading something on this the other day, I'll try to find the link for you.
Well I asked my friends who are knowledgeable with bandpass enclosures and they also said my sealed boxes might be too small. Tearing it out and rebuilding it wont be a big deal because I didn't expect this to work perfectly the first time.

Good luck with the rebuild, keep us posted.
why not just slide the baffle towards the front of the vehicle a little? that would make the sealed portion larger![]()
