I have a JL 12w3v2 sub. Dual voice coil. What is the best way to wire it to get the loudest and best sound out of it? I will have it wired to a 500/1 JL amp. Thanks

 

Wire it in a parallell, which means Connect the + On one voice coil to the positive on the other voice coil, then the negative of one voice coil to the negative of the other voice coil

 

yea what he said

 

depends. is your sub a dual 2, 4, or 8 ohm? the 500/1 JL amp puts out the same power if your sub is wired between 1.5 ohms-4 ohms.

heres the breakdown for you:

If your sub is the dual 2 ohm model- i would wire the sub into series. this would put your sub's impedance at 4 ohms.

If your sub is the dual 4 ohm model- i would wire the sub parallel. this would keep the sub's impedance at 2 ohms.

If your sub is the dual 8 ohm model- i would wire the sub parallel. this keeps it at 4 ohms impedance

just as long as the the impedance of the sub is between 1.5 and 4 ohms you should be good.

its the dual 2 model

 

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by mikeycivic &raquo;</TD></TR><TR><TD CLASS="quote">its the dual 2 model</TD></TR></TABLE> Series, connect the pos.(+) of one VC to the neg.(-) of the other VC, that will leave you with a pos.(+) and a neg.(-) to connect to the amp, no it makes no diff. which pos.(+) and neg.(-) you use as long as it's one from each VC.

Hint... try connecting the pos.(+) and neg.(-) to the amp both ways, [pos.(+) to pos.(+)/neg.(-) to neg.(-) and pos.(+) to neg.(-)/neg.(-) to pos.(+)] for phasing with the rest of the system, one of the two ways will sound better to you94

You have an IM.
Yes it was the correct way. 94

 

 

never got the im

i had to manually check

 

youre gonna blow your sub with that amp, i hope the amp is turned down or wired to two subs.

 

500/1 will not blow that sub dude

He has a 12W3v2-D2, a 300W DVC2 ohm wired in series for a 4 ohm load with a 1x500W RMS amp driving it, what he will have is lots of dynamic headroom.

He has a better chance of blowing s sub if he used that amp to drive two of them, as he would be under-powered by 100W.

It is better to be over-powered then it is to be under-powered. 94

 

Do you guys like that jl setup? I plan on buying the same amp and sub.

I put it in the other day, I bought a sealed qlogic box. I am VERY happy with the bass this sub produces in a coupe. Its loud,and clear. I wired the sub in series like fcm suggested and this things hits hard.
