system loudness problem

[M Dot Holla 10+ year member]

i have the 2 hybrid 12" re sx/hc or whatever subs. they are sx and hc i beleive. Anyways in my buick i had a really big box that was ported to about 35 hz i beleive. I run them on hifonics tx1005d. It was really loud on bass tracks and got so low..in my opinion.

Now I have a jeep liberty which i thought would be a lot louder now that i dont have a trunk and i have a suv. My box didnt fit because it is too deep of a box. So i bought a 2.5 sealed box. it is 1.25 cu ft per speaker. Its all the same but the fact that its a different box.

The problem is that I dont feel the speakers are anywhere near as loud as they used to be. They dont get as low as the other set up. It also seems like they get distort but not really..its the sound when it seems like they are getting over worked. I cant explain it.

Is there something wrong with my setup or is it just the change from ported to sealed that is upsetting me?

maybe go back to a ported box

its probably a combo of a prefab box and going sealed

I seriously doubt it is your gains. You can expect a fair amount of loudness reduction reduction when going from a ported to sealed application. The box is much less efficient, therefore needing a lot more power to get loud. I would go back to ported.
