I am going to go through and drop the SAZ-1000D, SAE-1200D, SAZ-1500D, SAZ-2000D, SAZ-3000D, and SAZ-3500D in the Jeep and do a power clamp test so we have a rough and UNIFORM comparison between the amps in the same setup.

Test Frequency - 50 Hz
Test Load - 4x SA-12s all in parallel for 0.4375 DCR (1/2 nominal)
Test Electrical - 6x Stinger SPV-70 + 225-Amp Alternator (vehicle only at idle)

Amp gain set to 1/2 - Head Unit Sub Control 10/10 - Head Unit Volume 50/50

Setting gain to half on each amp is, of course, not an exact match... but for the sake of roughly comparing the amps I think it serves the purpose.

---------------

These are not necessarily definitive tests on the amps.

All applications are different and I could have probably squeezed more out of an amp here or there... but for the sake of this test I just set the gain knobs to physically 1/2 way up.

Just a rough guide to show what the amps can do!

I may go back one day and do an SPL comparison as well -- as we have seen up to 1 dB increase from the 3000D to the 3500D even though the power test doesn't seem to indicate as much. With the SPL portion I would sit down and tweak knobs until I got maximum SPL per amp.


I tested amps from smallest to largest (for the most part except 1200D was tested last) -- so the batteries did not have a complete full charge by the time I got to the big amps, just a few minutes of alternator charge time... that just means the bigger amps will produce more than posted if I had a complete charge. This was mentioned in my initial post so I thought I would post it here as well.

I must say that little 1200 is a beast.. still have not played with my 1500, looks promising

you can cook bacon shirtless if you're not a pussy...lol


not hatin, but am i wrong here it looks as if the amp is not grounded its hooked directly to the battery. it that the way it should be.

Thanks and no problem :)

So far that box had done a 154.7 for me with the SA-12s... with just two 1500Ds it'll do 153.0 @ 47 Hz!

Wow I am surprised at the 1200d and the 1500d! Seems I need to get my electrical better so I can use the full potential of the 1500d!

Breaking in a sub is like breaking in your girl before you pound her....

very nice results. any testing on the 4500d :P

i was thinking leave the 12 sitting in the box in the hole and duck tape from the bottom of the sub to the bottom of the baffle so the sub doesnt free air. would that work?

I've done various testing on the 1500s, 3000s, 3500s, and 4500s on 16v if you look around. Since I no longer have a 16v system in the Jeep it won't be possible for me to do a test just like this one, though. The 1000 and 1200 won't like 16v much.

$160 Sony Xplod from Best Buy -- lowest one with a USB plug. Works great for me :) No signal processors or line drivers.

Would it be possible next time you do a test like this to get current draw numbers too?

Wow...am i reading this correctly...slightly above 1 ohm, at 12.8 volts the 1500 made 1900 watts? Holy sh!t..so wouldnt this thing easily break 2k on a solid 14+ v system. Damn that is insane.
