So I'm working on my Trans Am. I have 2 "Stealth Boxes" each are 0.75ft^3 gross. And I'm debating on some subs. Got roughly 1000 watts to throw at the pair.

The two subs I'm really looking at is the Sundown SD4-10 and the Image Dynamics IDQ 10. Both should easily handle the power. Conventional wisdom says the IDQs play a little lower because their EBP is 39 and the EBP of the SD4 is 43, but when I model the subs in WIN ISD this doesn't hold true.

My main goals is the best average output between 30Hz and 60Hz, but I'm biased towards the 30Hz-40Hz, I like the lower bass quite a bit more.

Here's the output across the 30Hz-60Hz range for both subs according to WIN ISD, feel free to double check as I could've messed up somewhere in the parameters.

Sundown SD4-10 in 0.66ft^3 @ 500 watts
30Hz: 102.164db
40Hz: 106.99db
50Hz: 109.617db
60Hz: 110.664db
Average: 107.36db

Image Dynamics IDQ 10 in 0.68ft^3 @ 500 watts
30Hz: 99.677db
40Hz: 105.337db
50Hz: 109.52db
60Hz: 112.114db
Average: 106.66db

So I'm clearly leaning Sundown here. They're $320 each, while the Image Dynamics are $240, so $160 more. But that's not enough for me to warrant less performance.

So with all that being said, what are some other subs I should consider taking a look at? I have about 6 inches of mounting depth to work with.
 
The Dayton's are good recommendations.
Look at Adire Audio

Image Dynamic subs do well sealed. I've built and installed boxes for ID subs. That may actually be one of the better choices. Another brand you might check out is the Focal.
 
I'm personally not a fan of most Sundowns in sealed boxes. You want a sub that gives you a decent Qtc and a fairly low Fc (sealed box specs). You want to look for woofers with lower Fs's, small-ish Vas maybe, and somewhat lower Q values- it's all relative. Since sealed boxes can only be tuned by size, and you're limited in size, so that means you should find the sub that will work best in the airspace you have.
