Hi guys, I am wondering if I can full my amp (outlaw model 500) that the connected speakers are 4ohms insted of 8. I currently have polk RTI a7 with is 8 ohm speaker. The amp pumps much more power if connected to 4 ohm load. I think I saw a article or something that you can add resistor and make the load 4 insted of 8 ohms. Any ideas??
If you add a resistor in parallel you don’t gain anything but wasted power in the form of heat lost by the resistor and not going to your speakers.
It also puts more stress on the amplifier having a lower ohm load.
Connect your speakers and don’t worry about it. An 8 ohm load is usually better anyways. And that possible doubling of wattage from 8 ohm to 4 ohm is only a gain of 3dB. But you wouldn’t get that gain of wattage because half of it would go through the resistor, effectively delivering the same amount of wattage but stressing the amplifier for no apparent reason.
Edit: Apparently your outlaw only gains 1.5 times the wattage when seeing a 4 ohm
load. This means that if you added a resistor, you would actually lower the amount of power delivered to your speakers and stress your amplifier. A double no. Enjoy your speakers and stop stressing
Also do you even need the extra wattage? Can the speakers even support it?
