i am assuming that in series will be the best. in a sealed enclosure .. how much power do i need and at what ohm? any ideas .. cuz i been told random numbers and i dont know who to believe.. suggestions on amps would be tight too

i believe that rms power on those babies are 500 watts so if you got money get a ppi 21400.2..i was gonan get one but it would lkill my car if i didn;t et like a 15 farad capacitor and an extra battery
you could prolly pull it off with like 800 watts though
but remember the good brands like ppi, rockford, kicker etc. underrate their power

The Continuous Power Handling of each of those subs is 300 Watts. You have Dual Voice Coils so you can either connect the two voice coils of each driver in series (+ to -) to each other and then the drivers themselves in parallel (+ to +, etc.) for 2 ohms impedance... this is the option I'd recommend. I'd also recommend a 1200W amp such as the Hifonics XI-ZEUS rated at 1200 watts x 1 channel into 2 Ohms (bridged).

If you have an amp that is stable down to .05 ohm you can connect the two voice coils of each driver in parallel (+ to +, - to -) and the drivers themselves in parallel. This will kill you amp quickly if it's not rated to handle a .5 ohm load.

See www.jlaudio.com for much more info.
Hope this helps.

blkacc99: reread my post above - The W6 has DVC and can handle 2 ohms parallel if the voice coils are wired in series.

The W6 have dual 6 ohm voice coils. That means you can have a 4 or 1ohm final load. I'd get a class D amp. The Cadence A7HC is nice it does 1400X1@1ohm and runs $415 at woofersetc.com. The DEI 1100d does around 1200X1@1ohm costs about the same but comes with a remote bass volume control. Stick with class D though, it's more cost effective.

How'd you get 4 ohms from dual 6 ohms? If you wire the two voice coils in series then parallel wire each sub - you get 2 ohms no?

i;m just curious.. how do u figure out ohm load? when in series and parallel?

i thing the JLW6 is best use either one or three.
if u use one, the best is to wire the coil in parelle then it will give u 3ohms load.
if u use 3 W6, wire each speaker in series and parellel form one speaker to anohter and this will give u 4 ohm load.
i think u need at least 900rms.

YOU DO NOT GET A 2-OHM LOAD OR A 3-OHM LOAD WHEN WIRING 3 JL AUDIO W6 SERIES SUBS IN A SERIES-PARALLEL CONFIGURATION.

Wiring the voice-coils in series will give you a 12-ohm load. Wiring three "12-ohm" subs in parallel will net a 4-ohm. If you added another sub to the trio, the load will then be 3-ohms.

ME has been the only one to give accurate information concerning impedance. You can verify the info through JL Audio or use this online calculator (http://www.colomar.com/Shavano/impedance_info.html)

4drGSR98: Relax... no need to shout - you and ME are correct in saying that the trio should give you 4 ohms... I was kept thinking he had 6 DVC subs (like I do) for some dumb reason.

from what i have headr the w-6 is no better than the w-3, possibly teh w-3 is even better.

about the power for the trio, i would give them atleast 1000 watts.

If you really want to know what the wire config's are for 3 6 ohm DVC's...go to jl website

www.jlaudio.com

and go to tutorials and there will eb a section on wire your subs..this is the best place to go

if u read well then u will find my info is correct as well.
the w6 are dual 6 ohm. wiring one w6 up in parelle will give 3 ohm load.

BelMiro & eatsgti....I'm not trying to insult anyone's intelligence on this board. It's just a good idea to verify your information before posting a reply. As far as your entry BelMiro, I found these statements misleading.

"if u use 3 W6, wire each speaker in series and parellel form one speaker to anohter and this will give u 4 ohm load.
i think u need at least 900rms."

While I know what you mean by the first statement, a lot of people starting out in car audio may not. The second statement is also misleading. If you want to maximize what the 12W6 subs can handle in a trio setup then 900rms is good. I worked with JL Audio subs for over 6 years and and from my experience the 12W6 subs in a trio setup do fine with 300rms. It all depends on the equipment that you're using in the system. Again, I'm not trying to insult you. I just wanted to make sure that accurate information is being posted so that people new to car audio can use this board to make informed decisions. You might want to consider using spellcheck also, LOL.

i'm only running 750watts to them.....3 JL12"sW6 bridged=mono. I'm really under-powering them!!

When you are figuring ohms, here is how you do it.

if series, add the ohms of each sub. thus, 2 4-ohm subs yields an 8-ohm load

if parallel, take the ohms of each sub, and divide it by the number of subs. Thus, 3 3-ohm speakers (w6's with the voice coils already wired in series with each other) yeilds a 1 ohm load

3 dual 6-ohm speakers can ONLY be four, or one ohm final load (unless you series all connections, which is ridiculous)

All of the w6 speakers are dual 6 ohm woofers. the jl 8w6 wants 200 w rms apiece, the 10 and 12 w6 wants 300 w rms, the 15w6 wants 400w rms, and the 18w6 wants 500w rms.

When you buy an amp for 3 12w6's, get one that is rated to produce at least 900w rms at 12v. Ignore 14.4 ratings, and ignore peak ratings.

Remember, you get what you pay for

if you are curious about how learn correct install of vehicle electronics, get the M.E.C.P. study guide. The certification is about useless, but you learn alot of important tricks and information
