Quad 8" Sub Box, is it possible?

PMad · June 2, 2018

I found these subs: https://www.crutchfield.com/p_5751P2D212/Rockford-Fosgate-P2D2-12.html?search=Rockford_Fosgate_P2D2-12&skipvs=T

And this box: http://ground-shaker.com/index.php?option=com_hikashop&ctrl=product&task=show&cid=116&name=gs-jchvp212b-black-12-dual-ported-sub-box-fits-chevy-silverado-gmc-sierra-ext-double-cab-2007-2017&Itemid=104&lang=en

Its not quite going to get the air volume the speakers want, for a ported box they want 1.79 cubic feet, the box has 1.25 cubic feet, and since there's two subs, i believe that 1.79 should be doubled, so i'm not sure how that would affect the sound? I'm not sure what amp to use. I havent been able to find a decent one. I'm not buying anything until i'm sure, i'm still open to smaller speakers but i do want a big thunderous boom that i can increase and reduce as needed. I want more bass than i need.

Those will not give you a "thunderous boom". Anything you out in that space will not give you a thunderous boom.

Your best bet is these which actuslly afe prerty nice for being so small but you are very limited.

Yeah 1.25 cf for (2) 12’s is ridiculously small. It will work, but it won’t be nearly as loud as a bigger enclosure. It will be tight and punchy. I suppose you don’t have much choice though. I’d also bet those thin woofers he posted are super expensive.

Keep in mind any time you install 2 12’s inside the actual cabin, it’s going to be pretty f-ing loud even with a less than ideal enclosure

For subs I always recommend single channel D class. You could get (2) high quality 1x100w amps and run them at 1ohm each. Which if it’s a quality amp will be about 350-400watts rms each.

That's way to small even sealed. You have to take in account the displacment of the sub as well

Im trying to build a pretty decent setup, something that thumps pretty well. I dont necessarily need something that will put your heart into afib but something thats gonna make people say "Dayum!"

There's very little room, so because of the available cf, should i drop to 10's? Would that create better sound than the 12's because of the CF?

The DD Audio SL series that Nasty mentioned, those are $300-500 each, from what i was seeing anyway. Thats almost my budget for the whole system haha. I'm looking around $100-$150 per speaker, up to $200 for the box, then based on what i buy, $100-$200 for the amp.

With audio you get what you pay for I am a little biased and my standards are super high but 500 bucks for a whole system. Wont happen for anything even decent
