Is it safe? If I have 2 Dual 2Ohm subs and want to wire them with a Dual 4 Ohm sub (or maybe 2 4Ohm subs) of the same type, will everything go smoothly? Any input is appreciated.

 

BAD idea... very bad idea.

different impedances will cause different amounts of current to flow to each coil. the 2 ohm coils will get twice as much current as the 4 ohm coils, so you won't be getting much out of the dual 4 ohm subs, and you'll be overdriving the dual 2 ohm units.

 

thought so.
lol, great work for a physics/comp sci honours major eh? lol
christ i hate midterms

 

it is possible if you have the right number of subs what are thinkin of any ways

You could wire the the dual 2 ohm in series giving you a 4 ohm load . . . but the that sub will see the amount of power of each 4 ohm coil and then the power imbalance will go the other way. (each 4 ohm will receive x power while the COMBINED 2 ohm coils will receive x power, so each 2 ohm coil would receive x/2 power in this set up)
Or series one coil from the 4 ohm with one coil from the 2 ohm giving you 6 ohms; do the same with the other coils, giving you 6 ohms then parallel those two circuits giving you a 3 ohm final -> Problem - the 2 ohm will still see twice the power as the 4 ohm.

There is NO way to get equal power sharing for each coil while keeping them on the same amp.

 

I don't see it. I just tried multiple ways and could not do it. What suggestion do you have?

 

I don't see it either, without some type of voltage regulator (not worth it) it isnt possible.
