Sungsil Electronics L/N 110725. (3) potential difference across 4 ohm resistor. Tolerance: 5%. $2.65. with no evidence of mechanical damage. New. When you use speakers that have a higher impedance (8 ohms vs. 6 ohms), the sound levels will be lower, as the power (wattage) to the speakers will be lower due to the higher impedance of the speakers. Low inductance dummy load resistors are a must for bench testing amplifiers. Running a resistor in parallel will lower the impedance to that the stereo sees, but the actual power in the speakers won't increase.

The product line consists of over 250 models, including high voltage resistors, current sense resistors, chip resistors, high frequency resistors, rf resistors, load resistors, pulse resistors, and non-inductive power resistors. These resistors are slightly inductive because they have a wire element but many of our customers use them for audio loads with great results. Simply put, the maximum power an amp can safely put into a lower-impedance load is the original power times the new impedance over the old impedance: P2 = P1 * Z2/Z1 So if your amp can put out 150W into an 8 ohm load, it can safely put 75W into a 4 ohm … (RWF) 1344420-2.8: 2.8 ohm--11 amps, Edge Wound Resistor: 35.00 -Add (RWF) IC9033-2.8: 2.8 ohm--50 amps, Open Wire Wound Resistor: 75.00 -Add (RWF) RR155-2.8: 2.8 ohm-155w: Wire Wound Resistor made by Tru-Ohm, a Military manufacturer.
