omhs law / configuration

[mattj 5,000+ posts]

I have an Autotek MX-1300 and its not 1 ohm MONO stable. I have 2 MA Audio XL 12" DVCs and im trying to get the most out of the sub/amp. My question is, whats the lowest i can run it without blowing my amp up and how do i wire it?

1 ohm stereo?

2 ohm mono?

1ohm stereo = 2ohm mono

What is the impedence of the VC on your subs? That determines the ohm config.

oh sorry i thought i had that in there

its 4 ohm dvc

You could have a 1ohm or 4ohm load on your amplifier.

Is that 1 ohm MONO or 1 ohm STEREO? My amp wont run 1 ohm MONO.

This is mono. You can run 2ohm stereo (i.e. 4ohm bridged). You only have two options that are practical, unfortunately.

what are the specs of your amp...that'd help a little also.....how many channels and all that....

I have an Autotek MX-1300 (stats below)

Hrmm, should I ditch the 2 MA Audio 12" XLs and go for like, say, a DD 9512 in like a 2.7 cu ft box? If not a DD, could I get a few other opinions?

I have 1600 x 1 @ 2 ohm mono RMS available to push.

You could get dual 8ohm, dual 1ohm, or single 4ohm for a pair to yield a 2ohm load on your amplifier.

is http://www.ddaudio.com the only place you can buy DD? Ive always been interested in them.

also, do you know of any websites that have box dimentions? i am looking for mabye around 2.7 cu ft ported at 30 hz

Run a series/parallel setup for a 4ohm final load. Run the amp at 4ohm mono for roughly 600w rms per driver. As far as DD goes, if you join club dd you can get pretty good direct prices. I have a shameless plus though, I have the Elemental Design E12a which is built at the same build house as the DD's are. Its somewhat similiar to the DD 3515, just doesnt handle quite as much power, its good up to 800w rms. And they are dual 4ohm coils, may not be for you, but im selling them for $250 plus shipping if they are. email jlguy141@hotmail.com
