So you used a battery charger on it, which typically runs at 15-16 volts?

Very nice, we love this little amp.

It is being replaced by SD2000 and then we will have a pre-sale pricing for all you. And wont be just a name change, the extra 200W will come together with the new heatsink.

Here is what you asked:

Dimensions (H x W x L: in / mm)

 

SD1800 2.87 x 10.9 x 9.84 / 73 X 277 X 250

appreciate it murilo. lets say you hav nG do a test on that 7k of yours //content.invisioncic.com/y282845/emoticons/naughty.gif.94359f346c0f1259df8038d60b41863e.gif

ok so maybe ill get the 2000.1 instead of the 1800.1

any idea on pricing for pre-sale?

will you be having a sale on the 1800.1's to get rid of them?

Why wasn't the tests done with the engine on?

Just curious. I mean, if you're going to do a "real world" test, why not have real world variables?

I'm not trying to be a dick, but when I see issues with testing methodology I question why that is so.

No stock sale because Brasil market buy all our production,

I fight with the distributors in Brazil to bring amps to North America guys, eheheh.

So you used a battery charger on it, which typically runs at 15-16 volts?

A 12V charger would provide 2V above the 12.6V fluctuation voltage, and as it was a 40A one its voltage would drop to the same battery voltage since the amplifier would require more than that to give the 2370W in output.

lol.

murilo did you accept my skype invite?

Testing was done in a closed garage. Didn't really want to give myself carbon monoxide poisoning. I'll meter the charger under load and test the voltage and provide pics. Not to mention, the charge will put out maybe 14.6V max... and less under load because the amp was drawing more. It was to act like an alternator, since I didn't have my vehicle on.

I'll try to do another test with my truck on tomorrow when I'm outside in a more commercial area.

Thanks.

so you agree this isn't the best method to test with?

What would you like?

Tomorrow I'll try to snatch some more number truck on, and truck off.

Lot of power in that little amp.

 

[snoopdan 5,000+ posts]

I really don't care what you do. If you were being proactive you'd of kept a "real world" circumstance for your test in the first place.

Dont get me wrong, look - if someone came up with an amp that did stupid power output in a small footprint id be all over it. (wait, didnt they try that back in 1992 with Blade Technologies?)

so are you saying it wont do that power?
