I drive a 99 Nissan Sentra and I have two 10-in subs in the trunk in a box already the box is too big and bulky. I have no room in my trunk for anything! what are some links to some better box designs that would give me the most room in my trunk but still have my subs sounding good?! Looking to DIY . And obviously something that's not going to cost me an arm and a leg?

what else is in the trunk? Amps and processors? If not then i would do a raised downfire box. What subs do you have?

Bass = space, willing to give some up? Try one 10, or try 2 10” iso baric loaded ported boxe, or sealed. Save some space and still use both speakers.

Infinite baffle, but you will likely want larger than a pair of 10s

2 15s infinite baffle

Switch to a sealed box, or go with a trunk IB.
Larger cones are better in IB, but I run a single 12 that sounds great, I’m sure 2 10s will be good (and in future can upgrade to larger drivers for even better results).

In the Sentra though, you may need to do a bit of work behind the rear seats and under rear deck to make sure you have a good seal / separation between the trunk and cabin.
