[QUOTE="n2audio, post: 8676554, member: 540940"] 3 ohms is just a less common speaker impedance, so you don't see amps spec'd for power at that impedance. The Hertz amp above, with power output of 150w at 4 ohms and 250w at 2 means it's going to be right around 200w at 3. Without going into a lot of detail, that is a good amount of power for a pair of high quality speakers rated for 150w rms. Yes, the Hertz amp is pricey, but when you buy $600 components nobody is going to suggest you use a budget amp to run them. Here are a few others that would work well: [URL="https://www.woofersetc.com/c-3-amplifiers/c-30-four-channel/incriminator-audio-ia3-4-4-channel-110w-rms-x-4-class-ab-full-range-amplifier.html"]https://www.woofersetc.com/c-3-amplifiers/c-30-four-channel/incriminator-audio-ia3-4-4-channel-110w-rms-x-4-class-ab-full-range-amplifier.html[/URL] [URL="https://www.woofersetc.com/c-3-amplifiers/c-30-four-channel/image-dynamics-sq800-4-4-channel-800-watts-rms-sq-series-amplifier.html"]https://www.woofersetc.com/c-3-amplifiers/c-30-four-channel/image-dynamics-sq800-4-4-channel-800-watts-rms-sq-series-amplifier.html[/URL] [URL="https://www.woofersetc.com/c-3-amplifiers/c-30-four-channel/sundown-audio-sax-125-4-class-ab-4-channel-full-range-amplifier.html"]https://www.woofersetc.com/c-3-amplifiers/c-30-four-channel/sundown-audio-sax-125-4-class-ab-4-channel-full-range-amplifier.html[/URL] The Hertz again: [URL="https://www.woofersetc.com/c-3-amplifiers/c-30-four-channel/hertz-ml-power-4-4-channel-1000w-rms-class-d-amplifier.html"]https://www.woofersetc.com/c-3-amplifiers/c-30-four-channel/hertz-ml-power-4-4-channel-1000w-rms-class-d-amplifier.html[/URL] [URL="https://www.woofersetc.com/c-3-amplifiers/c-30-four-channel/p-12323-xdi-6004-arc-audio-4-channel-600w-rms-class-d-car-amplifier.html"]https://www.woofersetc.com/c-3-amplifiers/c-30-four-channel/p-12323-xdi-6004-arc-audio-4-channel-600w-rms-class-d-car-amplifier.html[/URL] [URL="https://www.woofersetc.com/c-3-amplifiers/c-30-four-channel/alpine-x-a70f-4-channel-175w-rms-power-density-amplifier.html"]https://www.woofersetc.com/c-3-amplifiers/c-30-four-channel/alpine-x-a70f-4-channel-175w-rms-power-density-amplifier.html[/URL] [/QUOTE]
