Question about Concept CC-452 Car Audio Amplifier

How powerful is my amp???

You are probably aware on how to use these output figures, but I'll write a quick explanation on the specifications for future readers anyways :)

The concpet CC-452 amplifier has the following power output specifications:

Calculated at 14.5 volts DC;

At 4 ohms per channel - 45 watts x 2 (RMS)

At 2 ohms per channel - 70 watts x 2 (RMS)

At 4 ohms bridged - 150 watts x 1 (RMS)

This means that your amplifier would provide 45 watts of power each for your front speakers, which are normally a 4 ohm load per side (45 watts for left, 45 watts for right), that's unless they are one of those exotic higher end brands (eg: Boston Z6s which are 3 ohms). Rarely, you will find speakers that are rated at 2 ohms per side, but in this instance the amplifier will provide 70 watts of power into each speaker. On your speaker specifications, you will find a value termed "nominal impedance" which will give you the ohm rating of the speakers being used..

On the other hand, if you "bridge" both channels into a single channel (using a diagram often marked on the speaker terminals of the amp), you could then provide 150 watts into a subwoofer (providing it was a 4 ohm woofer).

It's not recommended to use this amp bridged under 4 ohms..

Some subwoofers may be lower than 4 ohms, and you will not be able to use this amplifier for these types of speakers without risking amplifier failure. Also, some subwoofers may have 2 seperate voice coils, and you will have to use both channels of the amplifier seperately (not bridged) in order to correctly connect this type of speaker for use.

Add up all the wattages of the appliances you are using when they come on and go off including lights. fridges. freezers, fans , stoves, tools and every thing. add them all up and you will get thousands of watts called kilo watts . see how many you use per hour and you will get a kilowatt/hr usage rate. Find out the power cost per kilowatt/hr and multiply the usage by the cost and you have your answer. Or you can get a wireless transmitter that is clamped around the input line to your premises and it transmits to a receiver to inside your house (mine sits on the fridge) and it tells you the cost as everything is running . press the mode button and you get progressive cost and other modes are there as well. It is great because if I forget and leave the pool running I can see at a glance that something drawing a lot of power is running so I can check it out and turn it off. Ask you power provider about it or a good electrical shop.

Maybe a dumb question, but what do you need a transformer for a washing machine? Washers typically plug into a standard 120 volt 15 amp outlet. To figure out the wattage, use the simple formula, P=E x I. There will be a tag somewhere on the machine stating current draw, which is "I", "E" is your voltage, and "P" is your wattage which is what you'll figure out after reading the label on the machine.

Finding anything on this product other than a service manual seems to be impossible... HOWEVER do NOT believe any numbers you hear as an answer because I found for a Kenwood XD-A55 they claim power input is 130 Watts... YET they claim you can get 100 Watts RMS from each channel. This amp is so efficient you can get 70 extra Watts!!! One soon learns that power numbers given for consumer electronics are BOGUS.

Hello, First figure out what the load per leg is on your generator. Are you
using the 240 Volts because this is two 120 AC volts legs and they are 120
degrees out of phase with each other.

You will need to figure what the power factor is for each phase on this generator. To figure the power/wattage by using ohm's law. Voltage times Current will give you Watts. Example: If the generator is generator 240 volts the maximum current available is about 23 amps. The maximum current for 120 volts will 46 amps. Therefore, the maximum current per 120 volt circuit is 23 amps for one circuit and 23 amps for the second 120 circuit..

I would try replacing the circuit breaker with the same amperage breaker. Also, watch what the generator load is per circuit. You can install current meter for each circuit. This will give a good indication of which circuit is pulling more load than the other circuit. GB...stewbison

if you bought that equipment today then your answer is yes your amp will power the subs but if i was you and you want more bass I would go with a two channel amp or even a mono block amp that will be 1 ohm stable and if you decide to do that you might want to get subs that are dual 4 ohm voice coils and run them in series that will get you 1 ohm of resistance

You can try going to a lower wattage element. EX: Our oven can take a 2500 - 5500 watage element. The lower the wattage, it won't heat up as fast/hot.Plus it saves on your power bill over time. Go to the Ariston website, or find your element number and check the web for a lower wattage.

to find out the amps needed you need to take the wattage that is listed on the information tag on the door of the dishwasher. Take the wattage number and multiply that number by 1000. Take the figure and divide it by the a/c current used to run the dishwasher this total is the minimum amps need for the proper operation of the dishwasher.

Example 35 watts X 1000 = 35000 divided by power supplied say 120 volts 29.1 amps or 30 amps

Hope this helped

Take the wattage info off the unit multiply the number by 1000. Now take that figure and divide it by the power source being supplied. Should give you the amps at the final total i.e. 65w times 1000 6500 divided by 240 v =27.08 amps or 30 amps This is only an example always round up to the nearest round figure.

Hope this helped you

It should say on the label, but if not, you can multiply volts times amps to get the wattage.The power supply for these puts out 2 voltages (12V and 5V), so use 12 V to get a more accurate figure.See if your label has volts and amps listed, then multiply these to get wattage. Watt=Volt X Amp.
