Default Subthump box - Video Review

So I've decided on the subthump box and see they are listed as 7.125 inch holes for the 8 inch subs. Nothing I see on crutchfield is matching that. The sizes listed are 6.8125 or 7.0625. For those of you that do have the a Subthump box can you please share what Subs you have installed in that box so I can cross reference how much deviation is acceptable.


Update
Here is my video review

here is my overall system review

I'm assuming you're talking about the partition box with 2 8"s, since I think that's the only one they have for 8"s. I am running that same box with 2 rockford p2d4's. The issue with that box, is that it's large for 8"s.. It's about 2x the size a normal 8" in a sealed enclosure needs. Make sure when you look for subs you don't rush like I did, and pay attention to the recommended sealed volume for each sub. Pretty much any 8" sub will fit. Also, I'm not happy with the box fwiw. For the power im throwing at it, i've heard a lot better running a lot less power. I really think it's the location and overall shape of the car that subs just don't play well with.

Thanks! I've been paying attention to air volume. I think a hatchback benefits the most from subs that point at the glass at 90 degree angle, that has been my experience. Ive already had earth shattering systems in my youth, now I am just looking for full sound range. I will check out the P2D4 thanks ! also what amp do you run.

You can also get a sub woofer enclosure that fits in one of the cubby's in the rear of a coupe ...

You can buy either enclose that fits the right or left side .. or buy two that fits both cubby's

Great sound and looks like some factory install .. Comes carpeted that matches the OEM 'ebony' carpet

I considered one of those but I really like the partition for looks.

Here is what I have picked out so far
TWO Kicker 48CWR82 2Ohm (Bridged to 2 Ohm dual VC) 300rms 600Peak (sealed box volume: 0.4 - 1.8 cu. ft.) (Subthump box is listed at 0.41 cu ft)
Alpine S-A60M - 600 watts RMS x 1 at 2 ohms

I wonder if these would work in that box ? https://www.kicker.com/solo-baric-l7s-8-4-ohm-subwoofer Oh course you'd have to modify the openings to to fit them, but they can handle more power and go to lower frequencies than the Compr's.

For those kickers the recommended Sealed box volume is 0.5 to 0.75 cubic feet. The subthump box is Volume: .41 cu.ft. per sub so it is NOT recommended to use those subs with the subthump box.

I had to get rid of mine as the top would not sit correctly in the back. I had Kenwood excelon shallow mount subs in it.

Weird.. Maybe had a bad box or hatch latches, top or something. Never had issues with mine and the top.

True, but you could make up a little of the difference by adding some Polyfill to the box.
