Damn how did I miss that 15.42 Volts

You also know, that the .5 load test, is reactive right? .Not nominal....

Would you wire to like .2 ?

I thought it was nominal not reactive. Like nominal would mean that it is always .5 and a reactive load would change.

Could be wrong though.

Nope. That test, would be if you wired LOWER, hence why I said it would protect, if ran in another test mode.

The 1 ohm test, is like if you wired to around .5 or so....

No, the Dyno tests using purely resistive loads. It is NOT subject to any type of rise. If a test is done at 1 ohm, then that is what the amp is seeing for the entire duration of that test.

Now that being said, the dynamic test is much easier on the amp and electrical than the certified or uncertified tests. I would be very surprised if that amp stayed on for a .5ohm certified test.

And for the fact that he simply states they will not warranty the amp at .5 ohm. I don't get why a company would test at .5 ohm load and then not warranty if they are going to brag about results? Still great numbers and loved my 4500s.

Speaking as a Dyno owner and having done the tests myself, the 2 numbers that truly matter to me are the Certified and Uncertified. I dont know enough about the Dynamic test to really understand how that would translate over to a daily application. If an amp passes Certified mode, then in my book it is a good amp.

Now when bench testing an amp, you are testing it under the best possible conditions. Once the amp is in a vehicle, it is at the mercy of that specific vehicles electrical.

Things I would like to know about a bench being used to test amps.

1) What batteries and how many are being used.

2) What charger or power supply is being used to keep the batteries charged.

3) Is said charger or power supply being used during the test

From the tests I see here, I see a 15.5v, that tells me that 16v batteries are probably being used.

There is a lack of information here other than just showing dyno numbers.
