A bit disappointed.....
Fellas I finished my install, overall I am happy but a bit let down in the performance of the drivers side sub box jl10w3 low end result. It very punchy and responsive but just seems that it misses some of the low notes. Perhaps this could be because of my younger days of running monster set ups in my 3rd gen Trans Am and 2nd 300zx. Those hatch areas seemed to produce thunderous bottom end , even with small sealed enclosures. I currently have the crossover set at 80hz. Any suggestions would be greatly appreciated. I'm not trying to rattle the license plate off, just a bit more accuracy in hitting some of the lower notes.
Set up consists of:
Kenwood Excelon 576s
Kenwood Excelon Xr-1s
Kenwood Excelon 450-4
VetteNuts Drivers Side Box
JL Audio 10w3
JBL Power 6.5 Components Front
JBL Coaxial Rear
Kicker 4 gauge amp kit
Killmat door kit

The corner cubby boxes set you up for cancellation inside the cabin. Your solutions will be either:
1) Spend a bunch of money on fancy speaker-by-speaker time and phase alignment capability, then tune to phase it perfectly for one listening postion
2) Address the root cause by moving the location of the sub to a point where the standing wave doesn't naturally inhibit itself. For me, I got way better results with a partition box that pointed the sub(s) toward the rear from a position in between the wheel wells. This creates a smaller "rear cavity" which more efficiently vents to the "front listening area" without fighting its own standing wave or the output from the door speakers.

I gave up on cubby boxes being able to reproduce the sound that I want. You can try stuffing it with poly-fill. I've heard mix results. Cheap enough to try...
Switch to a slot ported box to fit in the front area of the hatch. JL Audio tech will help, just give them your overall dimensions.

I have a similar set up to yours. Have a JL Stealthbox with a 10w3v3-2. Previously powered by a non mono 300w amp and it sounded good but not what I hoping for. Recently the amp croaked so last week I had a JL XD 600/1v2 mono installed to power the sub. It’s a night and difference. The power has improved dramatically and the quality is stellar. It really hits clean. I have the watts turned down so it’s not running full tilt yet the sound is fantastic.

But to help you, yes tuning will help. BUT! There is only so much tuning flexibility without a DSP. I used to run two 10W3's (4 ohm) in my Cobra. Each was on 250W RMS and they managed 128.9 db. Not too bad. Unfortunately, there is always a trade off in audio. C6's have a ridiculous cabin gain, something I've been fighting for years now. I have a 10W7AE in mine, on 600W and it's not enough. Someday we'll have to meet up and I'll show you what I mean. Sub woofer positioning is critical in C6's and the Stealth boxes do not help with big output. A rule of thumb, to increase output 3 db (at max performance) you need either double to cone area, or double the power. If you do both, you'll add ~6 db. Six decibels doesn't sound like much, but trust me, it is a BIG difference. I'm happy to help you, even when you're ready for tuning. Shoot me a PM with your number and we can talk about it.
