2 Enclosures of different volumes

[Flex68 10+ year member]

I am glassing two separate sealed enclosures for 12" subs. These are going in a confined space, under the rear seat of Dodge quad cab. This is a daily setup, with around 800WRMS planned for each sub, to start.

Due to the differences in the underseat wells, I am looking at the rear passenger side being at 1.1cubes, while the driver's side will offer 1.3cubes... about a 15% diff.

Since I am geared more towardsr SQ, I know that this is not a good thing.

Is it feasible to simply add polyfill to the smaller enclosure, or will I have to "short" the depth on the 1.3cuber to bring it down to 1.1 ?

How much luck you think I could expect if I try to EQ out the differences if I go with poly?

(Due to planned placement of my mono amp, glassing all the way across to achieve common chamber is not an option)

i would put a piece of 2x4 in the larger one to even it out

depends on youre subs if you need the extra room then i would stuff the smaller side but id youre subs like the 1.1 cube the just equalize the larger side. a pair of 10s in 1 cube sealed will sound great and dig deeper than 12s in that space.

off topic but how do you like your ram? im considering buying a 2012 crew cab big horn but im not much of a dodge person and know little about dodge.

Actually, I am giving serious consideration to going with 10s....thinking along the lines of IDQ or IDMAX. Or maybe JL W6, TC, or SSA.

Adire or Blues Audio would be sweet, but hard to find

I would fill it with poly fill if it but I don't really see the .2 making a

Huge difference gl finding a pair of Adire 10s I had to look for ever for a pair of 12s an now one sits lol
