Posted May 1, 201015 yr i want to have a test bench that i can test subs and amps and speakers on maybe even one that i can test how many true rms watts an amps is i have an extra head unit and some speakers i can hook up and a couple amps that need testing i just dont want to pull out my system to test them. how would i go about setting up a test bench? what do i need to set it up if someone has one can you take a video of it and show how you hooked yours up? please and thank you
May 1, 201015 yr Power supply, DMM, clamp meter, osscilliscope, tone generator, dummy loads (high power resistors).
May 1, 201015 yr if u want a bench to test amp output.. u need 12v batteries, not a power supply. Power supply that large would be in the thousands of dollars.U will need a battery charger and the thing that sucks is u will be testing off battery only so the voltage will not be that great on large amps.
May 1, 201015 yr oldskool, can you elaborate a bit? high power resistors? what are those and how do they work, also i can imagine what a tone generator is and would do.. but never seen one. Any links? im guessing power supply would be a battery

Any links? im guessing power supply would be a battery Dummy load resistors = Wire Wound Resistors,High Power Wire Wound Resistors,Chassis Mounted Wire Wound Resistors,IndiaPower supply for head unit and processors.Batteries and battery charger for amplifiers

May 4, 201015 yr maybe get 2-dmm's so you can measure both current and impedance or voltage at the same time that way you can find the output of the amp(s)I did this back in the day it was pretty fun. i tested an 1000rms amp and i paided about 120$ for the resistive load i used wire wound resistors! I know wire wound aren't good b/c the impedance will change as you increase the frequency but i was at 50hz so it was all good! llol! and yes i used an oscope! and function generator! other then that the amp got like 1150~ i forget the name of the amp but it was sure fun times!!and for some reason i cant' find the pics i took! send me a p/m to remind me to look for some pics for you if you are interested!
