Dual!!!!!!!! 2...

what are the differences

Single 12ohm.

Well first off, what you mean you'll be running either 2ohm 1000w or 2ohm 2000w? Do you mean you'll be running an amp that can do 2ohms, just not decided on what your wattage will be? Or is that a typo?

If you need a final impedance of 2ohms, you need a dual voice coil 4ohm subwoofer. Not 2ohm. With a single sub, with dual voice coils @ 4ohms a piece, you can wire the voice coils in series (+ to + and - to -) and you'll have a 2ohm load for the amp.

If that was a typo, and you really need 1ohm final impedance, then get the dual 2ohm subwoofer. Wire it in series for a 1ohm final load.

Basically heres how it works...

1 sub - dual voice coils @ 4ohms, can be wired in series for 2ohm final load or parallel for a 8ohm final load.

1 sub - dual voice coils @ 2ohms, can be wired in series for a 1ohm final load or parallel for a 4ohm final load.

you can wire a dual 1 ohm to be a 2 ohm subwoofer as well.

Wire positive from amp to positive on first voice coil, then negative on amp to negativeo n the other voice coil. Will see a final load of 2 ohms

Or the dual 1 could be wired for 2 ohms..

I meant to say 1 earlier.. lol

you couldnt be more wrong.........wiring a dual 4 ohm in series gives you 8 ohms and parallel gives you 2 ohms............or you could wire a 1 ohm sub in series to get 2 ohms

just a quick ? so if i want a 1 ohm final with 2 subs then ill need to get dual 1 ohms subs rite??

to get 1 ohm final load you could have

a. two dual 1 ohm subs

b. two single 2 ohm subs

c. two dual 4 ohm subs

 

[youngcoke]

my amp will be 2 ohm stable

so should i get dual 1 ohm or a dual 2ohm sub

 

[goonandbuck 10+ year member]

my amp will be 2 ohm stableso should i get dual 1 ohm or a dual 2ohm sub

if its a single sub....you need dual 1 wired in series

if its two subs.....you need dual 2's or single 4's

 

[BASS14 10+ year member]

to get 1 ohm final load you could havea. two dual 1 ohm subs

b. two single 2 ohm subs

c. two dual 4 ohm subs

ha i was rite....**** all this wireing shit ****s with me!!! i gotta get this shit figured out!

thanks!

 

[youngcoke]

if its a single sub....you need dual 1 wired in seriesif its two subs.....you need dual 2's or single 4's

you have the answer

than you

Or dual 4's
