1 ohm and 4 ohm same power output


Recommended Posts

I can't seem to find anything about it. Would be cool to test but it would be an expensive type of test. One thing that makes it hard was well is many amps do not display any amount of efficiency, and if they do it's for 4 ohms. But I am curious if you have a system running 1000w at 4 ohms of resistance, compared to 1000w at a 1 ohm resistance. Would the amps be efficient enough to need such a smaller electrical that the price increase for the bigger amps justify it? I also have another question when it comes to incorporating efficiency ratings to your calculations for laying out your system. If you happen to know an efficiency, where does that come into play when equating? Before you see how much amperage pull, or after? When using power = amp * voltage when you only have power and voltage, looking for amperage.

Turned mine up today at a light, guy next to me his steering wheel started moving and he looked over at me like I was a magician lol.

fuck the plating. look at what the main metal used is. you could buy unicorn blood plated terminals but if its just covering up dog shit, whats the point

I'll admit, half way through sanding that fiberglass in the rain and cold while I was all itchy I was definitely starting to question why i was doing this haha

I don't pay much attention to efficiency because it is easy to fudge and as you said, given at 4 ohms or something else nobody would run. I would guess that the efficiency gained by running at higher impedance would cost more in amplifier than a less efficient amp at lower impedance would cost in charging / batteries.
