93 chevy silverado small SQ build

Really charting out cabin gain is a pain in the arse and I would rather use an eq instead to get a flat response

I've never bothered but mapping by taking a mic a few feet from a sub in a sealed box outside, plotting points and then moving it into the car and plotting the points over top of the originals doesnt seem too hard

Not exactly the correct way either. Thats a good start but not torally correct

Ok, I took a dual sealed box and knocked the divider out. Ended up with 1.833 cft before displacement. I added a 3" by 8" port which seemed to equate to 32-33hz. Well it sounds great but seems to not really get that low with sound. Is the port actually tuned wrong? Or what might it possibly be tuning too?

The port is tuned right. But you should still be able to dig into the lower notes. It may not be loud enough for you but thats preference.

it can be quite hard to achieve loud and low with low power and low cone area. You can try tuning lower and it may help. But really its hoffmans iron law

efficiency, low end, small box size

You can only have two though some drivers ate very balanced and perform quite well

I built a box now for one. 4" port I can't remember the length. Box is 1.35 before subs and its amazing. I love it. Box was tuned to 30hz
