SA8 with passive radiators?

Was looking on eBay and found these

Definitive Technology 10" Passive Radiator - 4ADC | eBay

I've been contemplating the idea of using an SA8 in a very small box(1 cubic foot or less, 100% stuffed with polyfill), use either one or two passive radiators and install it under the center of my dash(my shifter is on the steering column), that way I still have full trunk space and have bass right in the cabin. Does the SA8 respond well with passive radiators?

I still have to figure out if that passive radiator can move freely in really cold conditions because some rubber surrounds turn really hard in cold weather.

Ive seen it done using 4 SA e8's to push a 15" pr. But it was in a trunk.

If a sub likes ported, it likes passive radiators.

Turns out the seller said they don't like cold weather, that or the guy really doesn't know.

Obviously some people here doesn't understand passive radiator and why they're better in certain situations.

i understand PRs my uncle has a single ten with 2 PRs under his back seat and it thumps like he has 2 12s. im just saying why not just use a small ported enclosure. it will work just as well.

and you can get a PR with a foam surround or rubber surround. not to mention if the PR didnt like the cold, ur sub wouldnt like it either....

I'm talking about temperature issue because those Def Tech PRs are made for home theater powered subs, no home owner keeps their house at below 50 degrees so some home audio speakers use less temperature-tolerant rubber surrounds. Car audio speakers are designed to tolerate the harsh automotive environment so they still work when it's snowing out, for example my subs still work just fine when it's 10 degrees F out.

I had a 12" Sony home powered sub(it has rubber surround, not sure what type) with a dead amp so just for giggles I took the amp out and ran the sub in my car with my old sub amp for a few weeks. It was snowing out and after a night of sitting the sub's surround was hard as a rock, the sub wouldn't even move as if the cone was locked up. It gradually started to loosen up when my car warmed up but that's something I learned about why using home audio speakers in a car might be a bad idea if you live in an area that gets really cold. Foam and cloth surrounds are less-susceptible to temperature extremes though.
