Need to change up the trunk and i have 300w for the sub. 150w 2 channels or 300w mono. I have 2 15" subs so nothing needs to be purchased just working with what i have.

not sure which way to go.

2 15s

I agree. Especially since you already have them.

Can you fit both the 15s in the same type of enclosure as the single 15? In other words, you're not having to do two 15s sealed vs a single 15 ported, etc? If not, and you can fit the pair, I would run the two as well.

what are the subs? It would depend on the power handling, if you are not able to over drive one of them with 300 watts, then i dont see the need to add a second unless you can buy more power.

Yes, please list all the information you can.

Sub model(s) {hopefully they are identical subs}, amplifier model, vehicle this is going into, music preference, end goal, etc etc.

Depending on power handling and power able to "really" be produced, running just one of them in a ported enclosure to proper specs has the ability to produce as much as both in a sealed enclosure, all while taking up similar or less cargo space. However, running ported requires the use of a infrasonic/subsonic filter, very low tuning, opting to not play music with audio recorded below the tuning, or running the setup at half or less rated power.
