I was wondering if you've tested th sax1200d, I'm putting it to 2-sa12's...

IIRC it did rated power with a rise to 2 ohms, or something along those lines. It was in a thread a while back, possibly the thread Jacob started when it first came out.

Edit: I found the thread. Here's Jacob's quote:

Two Stinger SPV-70 Batteries / 40-amp Power Supply / 8 awg wire power and Ground (this amp should have 4 awg)

Wired to 1 ohm nominal :

1170 Watts @ 12.5 volts

1.97 ohms after impedance rise

Wired to 0.5 ohm nominal :

1490 Watts @ 11.1 volts

0.85 ohms after impedance rise

---

Measured with my Extech True RMS power clamp meter several seconds into the tone @ 60 Hz -- this typically reads about ~15-16% less than a "dual peak hold" amp clamp test.

We'll do some more testing with a more adequate power wire coming up soon. The test bench 4 awg has the ends tinned so is a bit too big to go into the SAX-1200D terminals -- will need to get it in a vehicle.

Thanks guys! So it should do fine with 2sa12's until I jump to the 1500d

anybody measure the amp draw of a 3500d anywhere from .5 ohm to 2 ohm?

I don't fuck around. I go from zero to I hope you die in less than 2 posts

ah, how did you come up with a power figure for one of those amps if you didn't measure thee output voltage or current?

your tests seems rather flawed to me.

I'm pretty sure I know how to clamp amps :drink40:

In any event -- this is the meter :

When compared to traditionally utilized separate meters this meter reads lower 99% of the time as the meter captures the actual power at any given moment. Separate readings can have a time variance; especially dual peak-hold which can be drastically off.
