Different Vc of same subs working together

This is probably a stupid question, but I'm wanting to buy a dual 2 ohm tc-3000 and I'm looking to find 3 more, but am worried they will be quad 1 on some I find. Would these be compatible? Since they wire to the same impedance I was just curious

You shouldn't mix impedences

there can be problems with that bro wouldnt do it...

FYI: Quad 1s can be wired to a "dual 2ohm configuration".. shouldnt be an issue

Generally you don't mix impedances because if each sub is wired to a different load they will receive different amounts of power but if you were to say wire that quad 1 to 1 ohm and the dual 2 down to 1 ohm I don't see why it would be a problem...

It would be a problem because unless the coils are identical, they will have different impedences at different frequencies. You want them to behave identically at each frequency thus why we do not run different subwoofers. Just because a quad 1 can be wired to show the same NOMINAL impedence as a dual 2 does not mean they present the same load to the amplifier once actually being played. They most likely will not and you will run into cancellation problems, possibly low impedence problems etc. It's not worth it. You're much better off to get them and recone them to be identical.
