Front Speakers
Ok guys i got a tough one.
I'm on my way home tonight and all of the sudden I loose my front door speakers, no sound at all.
So when I get home I check the fuse on that side of my amp, its still good, I pull the speaker wires out of the amp and check those, nope, still coming back at 4ohms.
Since the back speakers are still running fine I know its not a power/ground/remote issue.
This leaves me to believe only a few things could be wrong:
1) I blew that channel of the amp.
Not likely, its a DD S4 that is only running at half, its only a few months old.
2) I blew the speakers.
Just because they say 4 ohms does not mean there not busted, but for both speakers to kick out at the same time, IDK the odds are against that.
3) The signal from the HU is toast.
This is what I'm leaning to.
Does anyone know how to use a multi meter to check the signal from the RCA's? I'm trying not to have to rip my dash apart again so if I can test the signal at the amp it would be nice.
I'm just not sure what setting to use on the multi meter and what kind of numbers to look for, whats good whats bad.
Can any help me out

Test your speakers, i doubt they blew. Try hooking the amps rca's on the back of the hu to the rear output to see if you get sound. run a long speaker wire from one of the 6x9's up to the fromt speakers to test the speaker with 
thats what i would do

get a 9v battery and pop the speaker at the terminals of the amp with the amp off (or the wires if u already removed them) that will tell u if the speakers are blown.
testing RCA is simple. with a meter put it on VAC. put one probe on the jacket and one on the male piece. the jacket is the negative if ur meter cares but most dont. you should get something like .6 to 1v from the RCAs
to test the amps output do the same thing just test on the speaker terminals. you should get a pretty high number there
On of the main things too look for when testing rca or amp output isnt really the number you see but more so that you get a similar number on all the rcas or amp terminals and that its fluctuating. If you get a number thats constant then somethings wrong (could be the meter too thou)
