I don't have 4 subs right now. I currently have two Pyle 12's in a ported box. I wanna get rid of the subs I have now. Then get a new 12(something better than Pyle) and two 10's(same model as whatever the new 12 would be, except smaller). Then I'd build a new box so that the internal volume of the 12" is separate from the two 10'sSo all 4 subs are pyles? Even one quality 12 in a ported box would hit harder and sound better than any combo of those pyles. But if you’re dead set on using them then I’d do the 2 12s in a ported box.
No budget, I'm really just trying to price it out for now, I'd be willing to spend as much as I need to do what I want. Sure, I'd get more power from better speakers. But I also want a better frequency response "range" for my subs. That's why I want one 12" and two 10". Just having two 12" sundowns or xfl's might be good for a lot of people that just want max volume but I've had that setup before(not my current setup tho) and I'm looking for something with good volume but more importantly great sound quality.What is your budget? Two Sundown or XFL's in the right box is all you need.

Do not mix and match subs ever full stop. Not different brands, not different sizes, not different enclosures. There may be exceptions like setting up arrays in a club or stadium but this will fail more often than not in a car. The idea of just cramming more subs/boxes in a car to get louder died in the mid 90's when those types of builds started getting crushed by people using less equipment but better quality and proper box design.The different subs would be in different sealed enclosures. It would be like having a 12" in one box and having another box with two 10's in it. I'm not trying to sound argumentative, I'm just trying to clarify what I mean. Are you saying having different sized subs in different enclosure within the same vehicle is a bad idea?
Iran a box with 3 8s and 2 10s in my CRX playing music at over 150dbs ... I had USACi rewrite the rules on sub size after that show ...it was the loudest streetbeat car ever recorded at a show in Baton Rouge ...I had a two door 2008 Wrangler that I ran 154s daily on 4 10s ... it was an awesome setup ..no back seat though ...it won SPL events at many showsSo my 2016 Jeep wrangler currently has a custom 3 cubic foot sub box with 2 12" pyle's in it. I certainly get a deep response out of them but not a whole lot of "high end"(I say high end relative to subwoofer frequencies) and they're not super punchy. Basically they're just good for a "low wavy bass"(if that makes any sense). I was thinking I could build a new box with just one 12" sub to maintain some of that low tone and 2 10" subs. I know that your not supposed to put different speakers in the same box but I would put an internal divider between the 12" and 2 10's so it would technically be two boxes in one. The new design will be mostly the same as the old one accept for the divider and speaker placement. I'm also using mdf to build this but if I get good responses to my idea, I might consider going the extra mile to build a fiberglass box molded around the wheel well. I'm also considering porting. I don't know if I should port the 12" side or the 10" side or both or none. I also understand I shouldn't run the three speakers on the same channel from the amp but I have a 2-channel sub amp, so I was thinking run the 12" to one channel and the 10's either in parallel or series(depending on ohms) to the other channel and tune each channel accordingly. So if anybody has done this before or has thoughts/ideas, I'd appreciate some input.
