AQ HDC3's -Wired correctly? Impedence issue.

[silenkiller 10+ year member]

Well, I bought two 2 OHM DVC subs so I could wire each at 1 ohm. I just read the ohms on my dimm and its showing 1.6-1.7ohms. Is this normal? If thats the case then the amps rated 2200 at 1ohm will only be putting out like 1500 or so? Oye. Any way to help this??

Is the 1.6 ohms after you wired the VC's in parallel, or is that an individual VC reading?

so basically 4 2 ohm voice coils? if so that can only be wired to .5, 2, and 8 ohms

I believe he is wiring each individual sub to 1 ohm. Am I correct?

 

[silenkiller 10+ year member]

Yeah, both sub to 1 ohm. Each sub has its own amp. Thats with the voice coils wired together.

I wired subs coils in parallel. + to + and - to -

did you touch the leads together on your dmm to find out what the true 0 is? one of my dmm's is off by .1, one is .3...I've seen them off by as much as .5

I don't think 1.6 is right then. Maybe call or email DJ? Or maybe you got some dual 4's instead of twos. Measure each VC individually and see what they say.

First things first, check the resistance of your DMM leads. Just touch them together and see their own resistance. Mine usually reads .2-.3

Subtract that number from the coil readings you are getting.

Secondly, read each coil individually and see what they actually are. Just because they are dual 2 doesn't mean they are going to read exactly 2.0.

Hm. Good point. Never thought of my own dimm's resistance. Its a pretty shitty one so I bet its going to be up there. So it should be pretty close to 1 ohm though after being wired correctly? I'll recheck tomorrow when I take my car back to my garage.

That is normal. I know with FI there dual 1 ohm usually reads .7 per coil.

you trying to wire each one to 1ohm i hope.. not together

yep
