Both voltage and current should match. Unlike other consumer electronic, amps have very specific voltage and current requirements. Look at the power input on your amp and make sure it is 14V 3A. Else find another adapter or power supply.

As long as the output voltage and amperage is the same or greater you should have no problems. Good luck......

If the Voltage and Power rating are the same (in some cases within a slight tolerance), and the plug fits, then I would say yes, go for it. All the AC Adapter does is to provide a power service to a device and it doesn't matter the device just as long as the ratings match.

I've always charged this device using a USB 2.0 or 3.0 port on my desktop. These ports are 5 VDC, & are capable of supplying 500 mA & 900 mA respectively. However, if you're using a USB port powered from your car aux port or from a wall socket, it may supply as much as 2.1 amps, which doesn't seem to present any problems for most of my equipment that's charged via USB (phones, MP3s, etc.), so I'm guessing this amplifier would be okay & I wouldn't hesitate to use it if necessary. Hope this is what you were looking for.

Not enough information is provided to answer your question. As a properly licensed radio amateur who has studied electronics, you will know to compare the current draw of your radio at full power to the amperage available from the power supply you wish to use.

Dear Demetre,I am the kind of guy who keeps useful extra items. The darn hub didn't work when it came. I read someone's comment that the power adapter was too small, so I looked in my stash of power packs [some people call them "Wall Warts!"] and found one rated 5V 1Amp. Since then, it has worked, but it's junky - the sockets do not fit smoothly. I notice that everyone else is using 3 - 5 Amps. The item they sent to me was tiny and it was much weaker than my 1 Amp unit.

I don't have idea , but you can try it , worse case scenario, you can return it. It is an excellent amplifier thought....

It's not necessarily bad for the amplifier, but keep in mind that it may make a slight buzz or hum while it's on. The power consumption of it while idle is very little. Though you should keep in mind that power fluctuations may damage the components if it's left on. Go for it.

Should be fine! This amp has plenty of power. No problems in the 10 months I've had mine.

it will sound good. louder than one might think. i love the little guy. i've had amps for way more $ and be equal or less than good. the el84 plus the 12x7 yadda yadda is the same as a Vox. A class too. sounds like a beatles amp, but raunchier. problems... the cheap ass plugs electric hook up thingsy is eggshellish. cut corners somehow i guess. if you can afford the speaker cab, i'd go for it. the speaker is voiced for the amp and breaks up when driven at the right time. lovely.

No, the idea for this one is a booster. The output is variable, but I don't think there's much overlap between its acceptable input voltage and its output. From my unit, it certainly couldn't go as low as a 5 v DC output.

That's a good match, IMO. An 8 ohm load will only make ~7-8 watts on this amp. You may start to see some distortion after half volume but even at that point, it's plenty loud. Just keep in mind, it's not a 100 watt amp..I had that amp connected to a pair of large 100 watt 8 ohm home stereo speakers and it did a great job! If you have a way to adjust the tone on the input audio, it'll rock! Very clean and accurate..

this will work perfect for you, this adapter is capable of supplying 6 amps but it's your device that actually determines how many amps it will draw from the 6. So as long as the adapter is able to produce at lease 4.58 amps (and this one is rated at 6 amps) then you're fine. If it were the other way around where your device requires i.e. 10 amps and you used this 6 amp adapter then you'll have a problem, you would burn out the adapter but in your case you're safe.

As long as the Voltage of the adapter is 12V, and the Amps rating is at least as high as the amount specified by the component it is plugged into, you'll be ok. If you need to, for short periods, you should be ok using one that is as high as 13.2V, since electronic components are built with a tolerance of 10%, but I wouldn't do it long term.

Bro I'll be 100% honest it's a good amp but it's for sure not pushin 3000 amps. It hits hard but it has it's limit and will shut off if pushed too hard...one you have it set and equalized right it's a solid amp I have 2 bridged subs on it and it works perfect. Out of the 4 mths I've had it, it's only overheated once and shut off maybe 3 times because I turned it past it's limit lol but overall it's pretty good man iwould suggest it for a good sound for sure!

Yes,its a small amp that does damage,I am using a Sony at 2 ohm 900 watts,great match.

You know I am not very qualified to answer this question. I don't know much about electronics. This also came with no directions so I had to youtube videos and google to find out what the different voltages meant.

This is a good amp but it's for a small system. Like for myself, with no loud music all the time, just once in a while to show off. Lol. Your speakers have a range of 400 watts if I'm not mistaken, so it should power it since it's a 500w model. But I would recommend you to get a 1k watts amp. Kenwood's a pretty good brand for this. At least mine does the work like a charm.

The current rating (in amps or milliamps) of a power supply is the maximum it can supply. Devices plugged into it will draw from the power supply only the current they require, usually less than the maximum. This operation is normal and expected. If you have a device like a headphone transmitter that at most draws 20mA, then you are fine. This power supply, rated at one amp, could supply 50 times more current than your device requires, but it will not harm either the power supply or the device plugged into it if the device needs far less power than the maximum that the power supply can provide. Please note that voltage specifications are different. For voltage, the supply and the device plugged into it must have matching specifications. If you have a power supply with a higher voltage specification than the device plugged into it, the device will likely be permanently damaged. If the power supply has a voltage specification lower than the device plugged into it, the device may not be damaged permanently, but it is also unlikely to function properly. Hope this helps.
