Im not sure I just baught it and I don't know much about the ohm loads. It's wired to nothing right now, I tried wiring to my power acoustik 2000 watt amp, and it went straight to protective mode. So now I am looking to get a amp that will run this woofer
I thought the HDCs only come in either dual 1 ohm or dual 2 ohm coils? I suppose you might have the D1 and get a single .5~.6 ohm load when wired in parallel.
But if each coil reads .6 or lower then you might have a burnt coil.
I'm just going off what the guy whole sold it to me said. It's the d1 ohm. I wired the two positives in my positive channel of my amp, and my two negatives into my negative channel, and my amp went straight to protective mode.
