I personally use this DMM. It's a Fluke 29:

I use mine for:

AC/DC voltage

Resistance

Capacitance

Continuity

It's a must have if you decide to make car audio a hobby. Mine was a little pricey, but you can get decent one at Sear's for about $30

so how would you use it to find the resistance, capacitance, continuity, voltage, etc.....can it be used to find actual rms wattage coming from amp...or is that even possible

Did you notice the selector switch on mine? Each position indicates a different measurement ( ohms, volts, etc).

Mine will figure true RMS with a hand calculation.

well i've got a DMM laying around the shop...how do i use it to calculate all of that

Were did you buy that one? Is it easy to use. The one I have looks hard *** hell.

use DC to measure voltages of batteries

use AC to measure voltage coming out of amp

use resistance to measure voice coils and what not

use capacitance to measure the size of capacitiors

basic electronic fundamentals

no problem

 

[302yota 10+ year member]

but when figuring the resistance do i place the negative pole to the - speaker terminal on the ampand positive pole to the + speaker terminal on the amp.....if so how would i go about finding the DC/AC

 

[p3bumpin 10+ year member]

what kind of subs are you using

 

[302yota 10+ year member]

kicker comps....i'm pretty sure i've got it at 1ohm but not sure....i was just wantin to check.....woulld i have to have the music on to tell the resistance??

I bought mine at Graingers:

http://www.grainger.com/Grainger/wwg/start.shtml?cm_mmc=PPC%3a%20Google-_-TPN%20-%20Brand-_-Graingers-_-graingers

It has a selector rotary swith that you move to each function. Move the switch to DC volts and position the red probe on the = and the black probe on the - and it reads out DC voltage.

You move the same switch to the appropriate function and repeat.

Got mine in 1994 and it was $179. Looks like they've gone up. //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif
