i know very little about electronics,so can someone please tell me if this will be a good choice to power a small practice amplifier.it's rated at the same voltage as the one pictured above.thanks for any and all info.

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.

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..

there is no set standard for rating watts, I have sold audio gear for many years, if you go to onkyo's web page and look at specs, you will see different numbers for different ohms and frequency, all manufactures do this. Very expensive amps will double there power into four ohms, but these are in the thousands of dollar range. The size of the power supply is what really makes a difference. If your speaker package is under the $2000 price range this should be fine, I bought this for my sons system.

Justin, I believe I can help. But You need to give me more specifics. #1-What are you using this for , ( a home stereo, or a PA system or as an insturment amp?)#2-What are you plugging in to the rca jacks?#3-What brand of speakers are you using (be specific, Brand and model-please)#4-any other items you are plugging in or out of this amp#Show me a picture if at all possible (of you entire rig) This is a very good amp if you use it as is meant to be used. I'm only trying to help, (if I can_so include all the info that you can. Extralite Justin, I believe I can help.

The website lists the nominal capacity at 600 watts. I don't know if that is accurate since I don't have the manual that came with mine. Having said that, those numbers are not that important since the companies that make this stuff don't always use the same formula to get their results. What is important is you pair it with a good, clean powered amp. I would recommend you get the most powerful one you can get with the least distortion. Just don't let the speaker clip...sounds like it's popping.

Absolutly! This is a fantastic amp. I have 3 of them, and by far this is the best one :)

No problem. I use in a one-channel antique jukebox for the phono input. Very few of the modern ones have a phono input anymore and they need a pre-amp. This is a road-warrior amp, and I have used several of them for different projects over the years. One takes the output from my surround sound unit and powers speaker pairs all over the house. Another goo feature is that the off-on switch stays in the position you leave it and can be used in a switched power outlet of a master amp or anything else you want it to respond to. I keep coming back to this amp and have been very happy with them...especially the price and availability.

I did some brief reading about how to match amps and speakers, and my understanding is that the amp's power rating should be less than that of the speakers--around half the peak rated wattage. But as well as power you have to make sure the impedance of the speakers matches the output impedance range of the amp. If you're running two 8 ohm speakers in parallel on each channel, that's actually 4 ohms, so check those numbers. We use this Grace BTAR122 in conjunction with two 80 watt Polk Atrium 4 speakers and it sounds fantastic.

Listen to the other answers. They are all correct.I will only add the following,I matched this amp with these bookshelf speakers (rated at 8ohms 120W)Sony SS-B1000 5-1/4-Inch Bookshelf Speakers (Pair)and the sound is tremendous! Love the amp!

1% THD is not "Audiophile" by any means. This looks like a good, straight forward, low cost, cheap amp, but it's not top quality. Two discrete power supplies inside running off a common transformer with cheap car audio amp specs is what it amounts to.

This wattage is good for larger items like a UK TV, video machine, amplifier, etc. A smaller, 200W type converter would be ok - always get at least three times more wattage than you need as some items create a power surge when you first turn them on and can trip a transformer out. Hope that's some help.

Thank you for asking. The powered outputs on this are stable down to 4 ohms. As long as the impedance on your speakers is high enough the amp will be ok. If the speakers are rated to the right power they will be safe as well. Have a great day!

After ur ?? I ran across a blog where a guy is powering a 350 watt car amp and a 12" mtx sub. "Im using a 250watt AT PC power supply that provides 10amps on the 12+v line. With this configuration I can easily power my amp and get great house shaking music now in my room." So rated at 30 amps continuous, u should have no problem. Is your input power fuse 30 amps or less? I would double check the maximum power requirements of my gear. This is not the quietest power supply, but u will quickly drown out any noise from this.

I would not recommend it, as the amplifiers may not draw power equally.... even if they are the same model, and the same manufacturer, no two amplifier's output will be 100% identical. Also, multiple amplifiers may cause the capacitor to drain it too quickly. If this occurs, the capacitor will not have enough time to to adequately recharge. If that happens, it will be as if you do not have a capacitor installed .... as the amplifier's power will be draining directly from the battery at that point (thus defeating the purpose of the capacitor).

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

i´m very disapointed of the performance of the 36db amplifier because I connected to the cable TV service and I don¨t got good response.Another Amps,Radio Shack for instance, works fine. I don¨t recommend to buy this one which do not have any Warranty. About Power supplies, Amazon never states voltages in all electronic devices. My suggestion is to put 110V - 220V or the last Autovolt; for this reason I do not buy any more electric devices. J. Humberto Gamboa (Bolivia)

I would think you would want a higher rated (wattage) amp. I used mine for running two 100 watt monitors. It worked well, I have since sold it.
