Dual 6 ohm voice coils only
Sorry brother, they don't work that way, on either account. They are dual 6 ohm voice coils. They are designed to be run in three's. The two that you want to get, is not your best option. For this application, they can either be run in 3 ohm stereo, 6 ohm mono, or a 1.5 ohm mono load. The last option is your best bet for the most power out of your amp, but unless you own a high current amp, designed to run at low impedances, it will likely overheat your amp, and shorten its life considerably. Your best bet in this case is either to buy 3 W6's, or go with two of the JL W3's...they are available in Dual 2 ohm, dual 4 ohm, or dual 6 ohm configurations. If you don't know about wiring them, just let me know, I'll be happy to explain it, i just don't want to take up any more space in this post......by the way, I have owned both of these speakers, and they jam. Pounding bass, with remarkable accuracy and Sound Quality. I currently own 3 10 W6's with a kicker ZR 600 rated at around 975 watts mono. They are wired to a 4 ohm mono load. It is nasty. Anyway, I promise you it is worth the extra money.
Good luck,
Lee
Can't wait for the new W7's....
