Dual 4 Ohm at 2 Ohm?

[Trender372 10+ year member]

Hello. I had a quick question. I have a 10" Alpine Type X sub, 4ohm DVC... and I was trying to wire it at 2ohm to run it off my amp. I was using this diagram..

However, when I wire it like this and connect it to the back of the box it still tests 4ohm with my meter. I know that these subs come with 'jumpers' that can be used, but I have misplaced them. Am I doing something wrong or am I just semi/fully retarded? (Rhetorical question btw..) I appreciate any help!

? the coils may read high + your DMM may read high...? and if both coils work 100% then it is right

Prolly only wiring one coil up...which would make it read 4ohm i believe

Pos to pos than a wire comin off to the amp

Neg to neg than a wire coming off to the amp

Yes, I have connected the two positive coils, and then ran a single wire to positive on the box. I did the same thing with negative, and ran that to the negative on the box. Tested it with my meter and it still reads 4ohm.

I tested my friend's CVX's earlier and it read 2ohm, so I dont know why it would be reading high.

test each coil independantly and see what you read.

I took all wires out and tested both pos/neg together for each set (VC1+VC1-, etc)and one set read 4ohm, the other didn't read at all. So I guess it sounds like a coil is fried. Right out of the box, too >.

Check it again and look at the tinsel to see if it maybe disconnected.

if you have a multimeter, make sure it's checking for ohms under 1k or something along those lines.

Ok, well I'm becoming more confused. I have two of these subs because I was eventually going to get a 1ohm stable amp to run them, but in the meantime I was going to hook one up to my Kicker 1000.1 I got the other sub out, and here is exactly what I did.

I tested VC2+ and VC2- together, and they read 4ohm. Just like the other sub, when I tested VC1+ and VC1- those dont test at all. So, just like the other one if I wire them up as shown in the diagram in my first post, they only read 4ohm. What is the possibility of having 2 subs bad, from 2 different places, brand new? I tested with the multimeter @ 200. Alpine wouldn't have done something like made it so you must have those jumpers to fire the other coil, would they? And yes, I am missing the jumpers for both subs bc these were loaded into an enclosure and tested by a friend on his 1ohm Orion along time ago, and he tossed the jumpers.

Anyone have any ideas?

e-mail alpine's tech support and ask. that is freakin odd though
