Subwoofer Ohm wiring
Alright, So im wanting to wire up 2 DVC 4 ohm subs. I was wondering, is it possible to wire them to run a 2 ohm load? i know i could run 1ohm, but the amp im looking at pushes 1000RMS at 2 ohms and these subs are rated 1000rms each. Thanks in advance.

maybe this could help ?

first is how much subs
second is dvc ?ohm
third is mono amp or bridged

goodluck

i belive that using 4 ohm dvc's in that arrangement would give you a 4 ohm load at the amp. (math: wiring the subs as series 8 ohm, and then parralling them to half would be 4 ohm...)

to get a 2 ohm load, you would need 2-2ohm, dvc subs.

it is just not possible with 4 ohm dvc subs.

though, i prefer to not run anything lower than 4 ohms-- it is just too close to a dead short for me to feel comfortable with..

In a series circuit, you add the resistance of each thing. If you were to wire these subs in series, it would be an 8 ohm load.

In a parallel circuit, you add the inverse of each thing and then take the inverse of that answer. Ex. 1/x = 1/a + 1/b + 1/c and solve for x.

In this case, a parallel circuit is your solution because

1/x = 1/4 + 1/4
1/x = 1/2
x=2

Short answer: wiring them in parallel will give you a 2 ohm load.

ok, thanks for the help guys, So i would be able to run 2 DVC 4ohm subs at 2ohm load if there wired in parallel? PaulF says yes but soundman98 says no? Also, lets say my amp pushes 1000RMS @ 1ohm as well as 1000RMS @ 4ohm, What is the difference if i wire and run them at 1000RMS @ 1ohm rather then 1000RMS @ 4ohm? Is 4ohm better then 1 or 2? I just really want to know my options so i dont go buy the wrong amp and subs since these subs retail 450+tax a piece :o

you can see on the website exactly how it should be wired that i gave u

just set how many what amp etc and ur done
see the pic by the story and its done in a minute

Ok, Ive decided to get the 4ohm subs. Im going to wire them to run 1ohm load. Could anyone recommend a good amp that puts out 1000RMS @ 1ohm? Im having trouble finding a decent amp. Im looking to spend under \$300 and would like to stay with the big brands like alpine, mtx, pioneer, kenwood etc. Thanks

each individual sub can be setup as a 2 ohm load like you speced. using all 4, 4 ohm voice coils, there is no way to connect the 4 as a 2 ohm load...

there isn't really a cheap 1 ohm stable sub amp-- that is this close to a dead short, and to get a amp that reliably puts out in that condition, it is not cheap...

So a 1ohm load is not as safe to run? I guess ill find a amp that puts out 1000rms @ 4ohm, or get the dvc 2ohm versions of the subs because the amp i was looking at puts out 1000rms @ 2ohm. I heard the 2ohm DVC subs in general are not as popular as the 4ohm ones?
