There was another thread that basically wanted to know if it's ok to mix (for example) a 2 ohm DVC sub with a 4 ohm DVC sub... I've actually been trying to figure out wiring configurations to do just that. So, I have a 2 part question for all the pros and those knowledgeable from experience:
1. Is it unsafe to wire multiple subs of different configurations together to achieve a specific desired ohm?
2. Would anyone be cool enough to list ALL possible safe wiring configurations to achieve 1 ohm? I know the basic ones, of course...
4ohmDVC + 4ohmDVC = 1ohm or 4ohm 2ohmDVC = 1ohm or 4ohm
... but what needs to be purchased to do a 3 sub setup at 1 ohm? what about a 4 sub setup? what if I have 2 4ohmDVC subs and want to add 2 more subs? how many ohms would they have to be to get one ohm?
I'm sure the answers will be lengthy, but will be much appreciated... thanks.
You can get a 1ohm load with 4 2ohmDVC subs: 2 subs - each wired in parallel and then together in parallel = 0.5ohm load
the same for the other 2 subs and then both pairs are wired in series together = 1ohm load.
As far as amp is concerned - you can mix & match brands, sizes, whatever, all day long as long as the final load for the amp is acceptable.
Regarding the subs, say, 2x4ohmDVC + 2x2ohmDVC subs (same brand and model) - I am not sure if 2ohm coils would respond exactly the same as 4ohm coils so I would put each pair in a separate box, because the impedance curves would be different I think
Once I almost did this: I had a a sub 4ohmDVC and a 4ch amp, so I decided to wire the amp into 2 bridged mono channels and connect each channel to it's own VC. I talked to the local "pros" and they said that the signals from those two channels would not be EXACTLY the same so I would ruin the sub, so at the end of the day - I didn't do it, but I think it can be done safely
I just though about it and I don't think you could do a 1ohm load with 3 subs (from the ones available on the market). You could do a 1.5ohm load with a 3 2ohmDVC subs.
