Am i gonna hurt somthing?

[mythyone 0]

I just got a 05 RE XXX off someone local and i took a DMM to it and got a weird reading. When wired together it reads 1.5 ohms but seperate one reads 2.0 ohms and the other is sitting @ 4.0 ohms. Would it be bad to run it at the 1.5 ohms? And how does something like that happen?

Umm... umm.. i dont know what to say.

I haven't never reconed a sub before but i'm wonderin if it's possible to have 2 separate coil readings from an improper reconing.

I know its got me confused too. I just didnt know if i ran it like that if it would hurt the amp at all

oh no, if your amp is at least 2 ohm stable and you wire it to 1.5 ohm, then you are fine!

A dual 4 ohm sub wired to 2 ohm usually sits at 1.4 ohms.

Some RE subs sit at 1.2 so you are definitely fine.

Possible bad solder joint?

If the coils are measuring the way hes says, one coil is going to receive twice as much power as the other.

yea ur right, forgot to tell him that, duh! hehe.

IT's the same principal as running dual 2s and dual 4s together on the same amp... not a good idea.

It "might" not hurt anything but i wouldnt do it personally.

Funny, i just completely changed my answer, lol

Amp is 1 ohm stable. i just retested the coils from the tinsel leads and one reads 2.4 the other is reading 2.2 ohms. I talked with the guy I bought it from and he said that the terms may be rusty and messing up my reading. Im gonna clean them up and see whats going on.

ok, if u got the 4 ohm side to read down in the 2s then there isn't anything wrong then... or at least that WAY wrong, hehe.

Your DCR values are still off though.

A dual 1 ohm sub should read 0.6-0.8 per coil.

A dual 2 ohm sub should read 1.2-1.8(yea 1.8 is high but i've seen it before) per coil.

A dual 4 ohm sub should read 2.8-3.6 per coil.

I don't know what type of sub you have so go by this.

You do have an RE though.. maybe it is a dual 4 ohm and they just got the resistance super freakin low on the XXX.
