Today, for the first time, I used my amm1 on a strapped pair of amps. Not that it matters, but the setup is 2 Sundown SCV 6000 strapped at 1 ohm. so each sees .5 nominal. I clamped 5800 watts through the positive side at .8. 

Since the amps are STRAPPED, does that mean that i was clamping 5800 watts out of 1 amp or both amplifiers. and was it seeing .8 ohm per amp? 

Please help lol

p.s. nice to be here again. been a while!

I would say that would be your total combined power because strapped amps work as a push / pull configuration or in series basically. So you would be able to measure anywhere in the circuit to get the power reading.

Where did you have you + & - test leads attached to?  

 

You are probably seeing combined power.

I would put them on the wires going to the speakers for total power. If you had them on the same amp then you only got power for that amp -maybe.

Brandon, Ive done some playing around. My American Bass 4ch is bridged on my mids.

When I hook up my DMM to just my front left channel, I get voltage a.

When I hook up my DMM to just my front right channel, I get voltage b.

When I hook up my DMM to where the speakers acutally are, I get voltage c.

Voltage a = voltage b

Voltage c is double voltage a, or double voltage b. (However you want to look at it).

Clamping speaker outputs still requires looking at acv, so I feel that you need to double the power you clamped with the AMM.

I know, bridging =/= strapping

Because of this, you could clamp your DC power run from either 6k to confirm. If youre drawing ~300 amperes per amplifier, then you are actually clamping around 5800 watts total. Whereas, if you are clamping ~600 amperes per amplifier, then you are getting 5800wrms/amplifier.

Sorry for rambling lol... but that should be expected <3

If you have the test leads wired to the inputs going to subs, that is going to tell you total power (both amps combined).

I know this is an old post, but I couldn't find anywhere else on the internet that had the answer.

maybe positive to master and negative to slave positive. someone will say for sure

^Strangeduck hit the nail on the head with his guess

When you AMM-1 strapped amps, you do it like normal. Run 1 wire through the machine, then put the clamps on both amp's positives (one amp should have the positive wires from the subs [master amp] and the other amp will have the negative wires from the subs [slave amp])

the AMM-1 will then measure impedance and power from both amps COMBINED.

Two SQ2200s @ 1 ohm each

Juice box (34hz note the entire song) saw me rising to 5 ohms collectively (2.5 ish per amp) and clamped around 1500w
