Not to bring up an old thread but after reading this and another thread, I had to the research myself bc it was a little confusing as no one corrected this. The wj has a 4 ohm system, so the wk 2 ohm speakers will not last long, or the factory infinity amp, not sure which would give out first. So to use the wk kicker upgrades you would have to replace the factory infinity amp with a 2 ohm stable amp...
