Wait a sec, if you have DVC 4ohms, then each sub can be made into 2 ohms by connecting it in parallel. So if you put three 2ohm subs in parallel, you should get around 1.5ohms. So how are you getting .67 or 2.67? Just curious.
3 4 ohm DVC subs in parallel is .67 ohms. 3 4 ohm DVC subs in series/parallel is 2.67 ohms.
Okay I must be missing something in here. If you look at the pic above, option 2, it says 1.34ohms. So Help2, how do you get .67ohms using 3 4ohm DVC subs? According to the diagram, if you turn 4ohm dvc into 2ohms, and then connect them in parallel, you're suppose to get 1.34ohms. Is my logic way off?
Well if it was custom built for 3 speakers, then there's no way it'll sound better with just 2. Your best bet is then to leave the 3rd speaker installed but not connected. You see, if you seal up one of the holes, the cubic feet will be too large for 2 subs. But on the other hand, if you leave it in, it will occupy space giving you correct volume size. You can solve this problem by getting an amp that can handle the odd ohmage.
Yes that's the idea. But you can't get 1ohms from 1 sub caues you said it was DVC 4ohms. That connected in parallel to itself will give 2ohms. Anyhow, connect the rca from HU to both amps using a splitter. This way you know all the subs will be synchronized.
