[QUOTE="MROOD, post: 8711134, member: 678683"] guys, i bought 2 Alpine R-W12D4 subwoofers DVC subs They are DVC 4 ohm subs at 750 watts rms each I have an amp which is a JL Audio JX1000, capable of 1000 watts rms at 2ohm or 500 watts rms at 4ohm T[B]he manual says the amp will go into protection mode if it detects any load lower than 2 ohm[/B] So when I connect the subwoofers on a 2 ohm configuration (meant for 2ohm subs), [I]wiring guidance from the JL manual and alpine manual[/I] I get a 1 ohm load, tested via my multi meter which i bought just for this, it clearly shows 1 ohm If i connect the subs at a 4ohm configuration then the multimeter confirms 3.9 ohms But the amp will only push out 500 watts rms at 4ohm and with 2 subwoofers thats basically 250 watts rms to each sub, thats very low for 750 watt subwoofers My investigation leads to that you cannot wire 2x DVC 4ohm subs at a 2ohm configuration, [B]its either 1ohm or 4 ohm Ive tested many configurations and i cannot acheive a final 2 ohm impedance on my 2 alpine 4ohm subwoofers[/B] Am i getting this right or do i need to return the subs for an exchange Thank you [/QUOTE]
