Four D2 ohm subs wiring to one ohm

[RickyFriery97]

Alright so I have 4 L7 15"s D2 ohm

I have them wired exactly like this

Here's a pic of the wiring in the box

So I wired them exactly like the diagram and it reads .5 Ohm on my TPI scope 440..

Anyone have any idea why??

EDIT: it dosent sit right at .5 ohm it goes back anf fourth between like .3 and up to 1.3

on my sperry DMM it sat right at .5 ohm for a bit but it goes back and fourth also

its wired to a AQ2200D at the moment

There's usually some variance when you ohm out the coils, if each one was off by .5 ohms that would explain it, and that's completely reasonable and possible. Don't worry though, once they get power that will come up well over .5ohms anyway

thats only 4 boltsvoice coils, it's late and my head hurts so maybe I am just missing something.

thats eight bolts

1 coil of each sub goes to a set of bolts

the other coils is connected + to - with 8 gauge

EDIT: just saw your edit lol

the other 4 voice coils are connected together just like the diagram

thats what i was thinking

just worried me cause the one AQ2200D is temporary

it will be two AQ2200Ds strapped daily

so i didnt want em to be strapped at .5 daily

Yes I fixed my post to say voice coils instead of bolts (told you it was late and my head hurts!)

I hope you mean the + from one coil and the - from the other coil (on the same sub) other wise you are only using 1 coil from each sub and thus getting your .5 ohm reading (4 2ohm coils in parallel)

that is what im doing

didnt now it needed to be the positive of one coil connected to the negative of the OTHER coil

i will rewire them tommorow and see if it fixes it

either way if it was a .5 ohm load the AQ2200D handled it like a champ

thanks for the help

No problem! let us now if it sounds any better!

alright rewired it and that was my problem! im at 1 ohm now thanks for the help man

my 4 L7 15s on a single AQ2200D is almost as loud (to the ear) as with four crunch GPV2000.1s one one each sub at one ohm

plan is to have two AQ2200Ds strapped at 1 ohm

so is 4 D2 subs in parallel a .25 or .5 ohm load??
