Wiring Adire Audio Maelstrom mk1
« on: 5 Apr 2010, 09:55 pm »
Hi  haven't posted in a few years, but just lately i've ran into trouble trying to wire my Maelstrom.

I'll try to post a few pics here.  I have the 250W parts express plate amp.

Nice :) But what's the wiring problem?  :scratch: ;)

Wiring the 18 in its box

the maelstrom is rated at 4ohm and it's a dual voice coil. How would you wire it up to a 4ohm plate amp, what's the wiring configuration like.   -all the wiring inside the box

i looked at the crutchfield diagrams and they say that if u want to wire 1 dvc sub to a 4ohm amp, the voice coils in the sub needs to be rated at 2ohm. here's the diagram, perhaps someone more knowledgeable can help out.




or if your sub is 4ohm, you need a 2ohm amp output.

hence:




I dunno what else, i'm no pro.  :oops:

Look. You can wire the 4 ohm coils in parallel for a 2 ohm load which will probably still work with that PE plate amp, but (may) also make it want to puke and die. Alternatively you can wire them in series for an 8 ohm load which will be fine with that PE amp.

According to this page - http://www.audiodesignguide.com/av/av_sub.html - the Adire Maelstrom is dual 8 ohm coils. So you can wire the coils in parallel. Just measure each coil with a multimeter to be sure (you should get a reading of 6.8 ohms on one coil.)

Edit: Hang on - other pages say it was available in either dual 4 ohm coils or dual 2 ohm coils...  :scratch: you should just measure the DC resistance and that will tell you what you have.

Mike,

Here's some info (Ok, a lot of info!) straight from the horse's mouth:

[Edit: To save you time, the Maelstrom MkI is 3.4 ohms with both VC's wired in parallel or approximately 6.8 ohms each]

So if i do Scary's 2nd diagram, aka: parallel wiring, there will be a 4 Ohm final load   I picked up a QSC RMX 1450 pro audio amp a couple days ago.  6 months old for $250 cash.  it'll do 900watts in the bridged mode to an 8 Ohm Driver.    i have that Adire Audio Tempest in that ported box as well. BTW, is mr marv still here?  He did all the mdf - cabinet work.   I had thought i'd use the QSC for the Maelstrom and the 250watt parts express plate amp for the Tempest.  For years now i had just been using the Tempest and the P.E. plate amp.  So i was hunting for an amp for the Maelstrom so i could play both at the same time.  i decided on the QSC 1450 to do 900w to the Maelstrom setting it to the bridge mode.  Now i see the Maelstrom has two eight ohm VCs.  So four Ohm is the Obvious wiring configuration  i guess i really shouldn't complain about that either btw  So the QSC does 450w to each of the two channels to a 4 ohm load.  So i should use the QSC to push both adire subs.  And that prolly makes more sense than bridging a 1,400watt pro amp for one sub and using a 250w $99 plate amp for the other.  And that 15 in the ported mr marv box is great too

The Tempest i can't remember anything about either.  Well it must be 4 Ohms final load wiring if i'm using the P.E. plate amp.  I established this equipment in 2003. 

FYI for the wiring to try out the Maelstrom with the PE plate amp i did the positive wire from the amp to one of the positive terminals on one side  Then the negative wire from the amp to the negative terminal On The Other side.  Then one single piece of wire connecting the remaining two unused terminals, ie the remaining negative terminal on one side connected to the remaining positive terminal On The Other side.   I supposed the PE plate amp was seeing a 16 Ohm final load

What if by chance the Tempest is an 8 Ohm final load.  Can the QSC take a 4 Ohm load on one channel and an 8 Ohm load on the other
