Thats cool that explains a lot better what Bill did when testing my amps in my boat and how they actually determined how much power is really going to my Sub.

When i had the 1500.1 it was 1800 RMS and peaking at 3600
Then we put the 2500.1 in and got the higher numbers respectivly. I dont recall the exact V reading but i want to say it was around 48V or something but it was a couple years ago when we did the testing exactly.

We actually have the same method of testing as Mitch (in the video) although we have a power supply that is four times larger so the voltage will not sag when testing larger amplifiers. And, we are doing regular amp clinics where at designated times anyone can come in off the street and have their own amplifier tested. But you really need to have more than a DVM to do the testing. It also requires a distortion measurement tool, such as a distortion analyzer or an O-Scope. We have both. We like to stay with the CEA2006 standards (not WLS or JBF). Believe me, it can be very revealing. We have also had amplifiers sent off to an independent lab with 50K worth of test equipment and 3-phase supply, to confirm our findings. Like Mitch, we have begun showing the test results on products in the store as well as on the on-line store.
Consumers deserve to know the undistorted truth.

Thats great a retailer goes through all that trouble for their customers.

I trust what the design engineer says about his products.

Dude wow. You baited and trapped?

The start of the thread derailment started from your amp specs, yes. Many consumers appreciate good comparisons, enthusiast here on the forum especially. Your continually exaggeration of product specs/attributes matched with the respect users here seem to have for you creates a whirlwind of frustration for those that want solid info on the site.

You were not baiting people, they were passively trying to get facts into the thread without calling you out directly .... They were trying to be respectful. You notice you are always the one up in arms?

How much power an amp puts out and which boat looks the best are not the same question. Don't be ridiculous. Power is measurable.

it's 520pm in Texas and yup, Oklahoma still sucks!!

Yea i see your point KG.

Guess it doesnt matter to much to me right now when i think about it. Its not like a got a boat or a stereo any longer.

Maybe next season

Im just happy I was able to be apart of this successful experiment

[dusty2221]

It does feel good to know you were a part of something huh!?!

So i can tune my system with one of those Gizmos"

Joe,
If you are asking if you can tune your system with a Digital Volt Meter, the answer is yes you can. You will also need a CD with a number of sine wave frequencies (as most Class D dedicated sub amplifiers have a limited HF bandwidth), plus a distortion analyzer or an ocilliscope. You will want to avoid pumping a 1kHz sine wave through a coaxial at full power (very different from dynamic music power) so you will find clipping without the speakers connected. But this exercise only establishes the maximum gain at which any amplifier can be safely set to. For gain balancing between between area speakers and highpass to lowpass speakers, you will have to finish the old fashion way by ear.
