I have 2 US Amps Md3's strapped. My question is will both of the amps be putting out AC Voltage or just the master? I went out there today and on music my master was putting out AC volts but my slave was not putting out any AC volts. Both of my subs work and they are wired seperate so both amps are working but the slave is not reading any AC voltage.

your not supposed to measure each individually the amps work as one big amp the neg probe goes on the neg amp and the positive prob goes on the positive amp.

so neg. on slave pos on master. I was measuring the master and it gave around 70v will it alter if I measure the way u said?

the way i said to measure is the correct way. what your doing doent even make sense unless your amps arnt actually strapped? how do you have them strapped?

they are strapped the way the manual says to strap them

ok dude amps strap in diffrent ways please explain to me how you did it!

I have speaker wire going from the master to the slave in one of the neg terminals on both amps. Each sub is wired seperate, I have the pos of one sub going to my master, the neg of that sub is crimped to more speaker wire and goes up to the pos of the other sub, the slave amp, where they crimped together and the negative of the second sub is in the pos terminal of the slave amp.

I checked it the way you stated and it is the same voltage as if I just check the master amp

then thats your voltage. if your parallel strapping your amps your effectively creating one large amp. so the way you did it and the way i said it is the same.
