[QUOTE="squeak9798, post: 1409301, member: 555320"] No. You could use a resistor in parallel with the sub to present a different impedance to the amplifier (4ohm resistor in parallel with the 4ohm voice coil for a final 2ohm load)....but that's a worthless fix, since even though the amplifier would be outputting it's 2ohm power, half of that power would be wasted as heat by the resistor...leaving the subwoofer to only receive the same amount of power as it would have been if wired directly to the amplifier at 4ohms. There was an older product produced by Veritas and Stinger called the Accumatch....but they are pretty hard to find, and even then there are mixed reviews about them. I guess they went pop pretty easily, and most people were very unhappy with the performance of their speakers when having the Accumatch connected. So, overall....you're just screwed [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] Which is why having DVC subwoofers comes in handy.....
