Can I get close to same output with this setup?

[jeeper2269 10+ year member]

I have a 2018 Ford F-150 SuperCrew

I currently have a FI “12” “Q” series sub in a small enclosed that barely fits behind the passenger seat, with the rear passenger seat up.

I am wondering if there are any other options that would come close to performing the same, in a box under the rear seat.

I just can’t think shallow subs will get anywhere close.

Wouldnt know unless you give us dimensions of your under the seat. four 8s in a ported will smash your FI Q 12 if it fits. two 8s will be just as loud but peak a lot lower.

Which 8s?

I don’t have the exact demenstions right now

Still wonder if there are 4 shallow mount 8s that would get close

When I put the 12” FI Q in a larger ported box, it was so loud it tickled my throat and messed with my vision.

Could you use something like this?

The truck is at the shop getting everything installed. Picking it up tonight. The back seat has a plastic tray. I think I can remove it. I will try and see if there are some pics online. Otherwise I will get it tonight.

What kind of 8s would you run?

Getting everything installed?.. you mean the enclosure and substage as well? Did you decide which direction to take? Or is it still the single 12?

Should be about 54 across the backseat. 12 deep and average height is 7.5. I would recommend a seat lift to help with space.

bandit_kb seems that's the thing to do.

I'm wondering what the purpose of this thread is to begin with if he's getting stuff done at a shop.
