Can they check ohms on a amp? If so my DVM has 20M, 2M, 200K, 20K, 2K, 200/ which should I use...........

 

You mean how your subs are wired (load on the amp) ? Yes they can, just put the leads from the volt meter on the speaker leads that hook up to your amp. Put it on the 200 Ohm setting.

 

There are two, 200K and 200/ which? I tried both and they read a high number and keeps on going up and down..........

 

200, not the 200K(200,000)

 

I have two questions. Would a sub with a busted coil read off if its connected at amp? Could speaker wire if damaged(not able to notice by looking) cause volt meter to read off?

 

Don't measure with it connected to the amp. Disconnect one lead, then remeasure, you should get a pretty stable # - as long as the speaker isn't being moved in/out.

 

If a speaker wire is 'broken' as you put it, it will read just like the multimeter will- if it is not connected. Otherwise your impedance will be minimal (use the 200).

 

For some reason both subs(SVC 4ohm) read the same(4.2) but one speaker pushes harder than the other. An the one that does not push as hard sometimes jumps to high numbers before getting stable(other does not do that), is something wrong with my volt meter?

 

Have you tried just switching your amplifier outputs to each sub, and have you also tried switching the rca's to see if the problem stays or moves... It'd be a lot easier than learning how to use a multimeter.

 

Still the same. Is it possiable that sub with busted coil would read correct if so what are other ways to check?

 

The ONLY thing that you have left that you can do is...

While checking impedance with your voltmeter, find a good way to clip those leads to the spade connectors, now take a finger and GENTLY move the braided wire from the terminal to the cone... watch for BIG changes, if you see some one of these has worn out.

In SOME cases you can resolder a weak/worn out connection but you should also be able to visually inspect and find the bad spot, often where the factory solder or bends are.

Otherwise there is little to be done, since your amplifier is obviously ok.

 

Can a voltmeter check fuses if so which AC V, DC V, DC mA?

 

Yes, put it on the Ohm setting, and if it reads nothing, then the fuse is blown, if you get a reading, it should be good.

 

Let me get this correct, to check fuses it should be turned to ohms? 20M, 2M, 200K, 20K, 2K, 200/ which? Should it read a certain number?

 

If you are checking fuses, it won't matter where it is set at so keep it at your 200 ohm setting. If it reads a value your fuse is okay, if it doesn't give you a reading it is bad.
