The power supply (wall wart) clearly shows 12 volts at 2000 milliamps (2 amps) this is 24 watts, so how can the amplifier to be rated at 60W?

A lot of cheap amplifiers are rated on peak output, not the amount of output it can sustain for periods of time greater than a few fractions of a second. Given that the amp undoubtedly has a fair amount of capacitance, it should be able to exceed the output of the power supply for short bursts (ie: a drum hit in a song). Since those bursts are short, and only a few times per second, it should work OK, as long as the average was a bit under the 24 watts the power supply can produce.

If your old enough to remember, all amplifiers used to be rated in RMS watts at 1% distortion, both channels driven. Now they use some other lax standard that has little relation to electrical power.

My best guess is that the 12v 2a wall wart was the smallest, cheapest one they could find that could acceptably run the amplifier. I purchased an aftermarket 72 watt power supply for the amp to remedy this issue. If you're using this in a vehicle application you won't have worry about this as the vehicle's electrical system should provide all the amperage the amp will ask for.

The label is very skimpy. it does not have amps, watts, or hp. Sorry, I do not know.

Voltage is not measured in Watts.....5 volts. It draws 0.4 amp or 400 mili Amp most likely. (it also makes sense). But why are you concern about power input??

The power supply that comes with the amp is 36 volt. I doubt that a 19 - 24 volt power supply would work.

The online specs rate the power supply at 1Amp @ 120VAC. May be someone else will have the power adapter handy and be able to read its label for you. The unit only consumes 36Watts.

Its a 60W max transformer so I wouldn't think there would be a problem with 12 watts.

It says on it "120V 60Hz 2A". I am not certain, but I found online you multiply the Volt by the Amp to get the Wattage. So it should be 240 Watts. But I'm no electrician.

Please keep in mind I'm coming from an audiophile background but you do know the difference between 2000 and 4000 watts is 3db, right? Also keep in mind that these are transient/peak output numbers which probably don't translate into the real world. A 15amp 120V outlet can supply 1800 watts (watts=amps x volts). Assuming 100% efficiency (which no amplifier achieves anything close to that), that's it. These output numbers are fictional.

Rebecca. I don't recall listing the specs for the 90W adapter, but here's what's on the adapter: Output 19V 4.74A. Therefore, Power = Voltage * Amps = 90.6W. By the way, the adapter is still working after 2 years of service. I previously bought two of the 65W adapters to match the original one. Both of these only lasted ~3 months.

12v *20 amps = 240 watts. If you want to know if it can supply this stably, I don't know. It didn't come with documentation and I only use a little under 12 amps. I did measure the voltage and that was stable and actually 12 volts. So far, I haven't had any problems.

On the back of the box it says under "Electrical Ratings": 15A 120V, 60HZ 1800W. I don't see 240V mentioned anywhere. On the back of the unit, on the impossible to read white raised letters, it also only lists 120V. I think in theory a power strip is simply extending any power coming in. It seems like almost all this stuff is made for the world market and i would bet they sell the exact same device oversea's with different plugs and it works fine. I'd be tempted to go ahead and use it, but you're on your own. The maximum spike current is 12,000A, I don't know what amperage is used on a 240V system, but I think it's less than the US amperage. I'm liking it more and more as I use it. On the back of the box it says under "Electrical Ratings": 15A 120V, 60HZ 1800W. I don't see 240V mentioned anywhere.

It's an amp, it's connected to 120.Consumes 260 on max use.And provides u 150x7w.Makes sense to me ;)

I looked through the booklet and could not find a watt rating. I've always just plugged mine into the normal wall outlet to use. Haven't had any problems.

The power supply is 36 watts and 15 volts DC. I also have the plain Finnex Fugeray 48" (no red LEDs) It seems brighter, but is only 24 watts per power supply.

Their book specifies Max PV input power 12V/390W or 24V/780W. My PV output is max 18V at 21A. That is 378W (18 x 21 = 378) and does not exceeded their specs so I don't have any experience as far as exceeding the books specs. Going from a 12V to a 24V PV system will double your wattage without increasing your amperage however, in order to use that increased wattage without exceeding the 30A output current, you would also need to change to a 24V battery system. The output is rated at 30A regardless of the input voltage or amperage or battery voltage.

My BD200MTB indicates it at 2.0 amps not 2.5 amps. Assuming power factor of 1.0 at 120 volts, at 2.0amps Wattage = amps X voltage = 240W. At 2.5 amps: wattage = 300 W
