No real difference in sound, but in construction a single box usually requires more internal bracing as you will have larger sides. But if you will have a dedicated amp for each sub, I believe its easier to tune if they are in individual boxes, but I am only going by what ive heard. Ive always had a single amp for multiple subs. My current setup has each sub in its own box, but thats just how I designed it as I have it behind my truck seats, so I have one sub behind each seat and the amp in the middle.
Are you concerned about fitment? Like you need to build 2 separate so they will fit in? They would need to be identical in tuning to avoid cancelation issues.
