How can i tell how many watts my amp has because it does not tell on the amp?
get an amp reader at radio shack (costs about 5 bucks) turn on the amp and check the pos and neg and you will get a good reading.. good luck... Grant M
How many watts is 1.0Amp?
amps cannot be directly turned into watts, alot of it depends on how much voltage is being used. watts are a mesaure of energy or power. i dont have any notes from college with me, but W = VI^2 or voltage multiplied by current squared. I highly doubt that you would get anywhere near 2000W. There are many more power equations that involve different combinataions of voltage and current, but thats the first one i remembered. Even if it was being run at 240V at 1A its still only 240W.
How many watts can my amp handle?
never and i repeat never mix a 10 and a 12 inch subwoofer the two will actually have different sound wavelengths that once you have them in a car playing the same song it will sound like complete **** . You can definitly add another subwoofer to the amp even though it is only 425 watts but chances are even with two it will not be louder than just the single sub you have, If you seriously want a good bang for your buck look up ma audio speakers on ebay. they have a full line of speakers and amps that will keep your whole bill for 2 12s and amplifier under 400 dollars, now if you have some money to throw around, grab yourself some jl audios, they will shake your car apart, and you can find some cheap w1s and w0s. good luck
How many watts does an amplifier use to 2 100-watt speakers?
A speakers power is typically rated for both max RMS (constant power) and max peak power handling. The speaker can only get the power the amp/receiver is capable of providing.It is typically safe to provide 25% above the max power handling. Now keep in mind, a good amp can be rated for 100 watts rms, but it’s peak power could be 200. So don’t confuse rms vs peak power handling.Also very important to look at is matching the impedance of the speaker to the amp. Speakers that require a high current amp can kill an amp or receiver that’s not rated for them. Example being Magnepan Planar ribbon speakers and Martin Logan electrostats. Those are rated for a 4 ohm nominal impedance and will typically dip lower. Big vintage Infinity speakers are also referred to as “Amp Killers” because the impedance can dip below 2 ohms at high volumes in the low frequencies. This means the speaker has a lower resistance and will pull even more current from the amp. If the amp can’t habdle the current draw, it will go overheat and go into protection mode or just die completely. Most receivers and power amps are rated for 8–6 ohms. If an amp is a solid performer at 4 ohms, the specs for that amp will list a separate power rating for 4 ohms and will usually be 50% to double the power rating at 8 ohms. So check the speakers nominal impedance first before pairing an amp.And when comparing amp power ratings, the most accurate representation is the rating at 20hz-20 kHz. Not the rating at 1 kHz. The first rating scale is telling you you are getting x amount of watts per channel across the frequency range. The rating at 1 kHz is the power only for that frequency band. Some manufacturers will show both ratings or one or the other. If I see a rating at 1 kHz only, I typically walk away from that amp because it can mean the manufacturer is leading the consumer on.And if the speakers are very efficient like 93dB at 1 w per meter, you don’t need to provide a lot of power to get the most out of them. Klipsch is known for making very efficient speakers and many people power them very nicely with 10 watts per channel from a tube amp.
How many watts power supply do I need for a 1000 watt amp?
I haven't seen many people do this but I figured since I had the equipment sitting around I might as well use it. I've got a 1000 watt (500w rms) car mono sub amp. I want to power it indoors. Heard of people using computer power supplies to convert from 120v ac to the 12v dc. But to power my amp does that also mean I need a 1000w power supply? Not sure if it's an equal proportion. If that's the case, the power supply will be in the hundreds. At that point is there a good audio indoor amp that puts out the same numbers that anyone would recommend?
How many watts does an amplifier need to power 2, 12" subwoofers in order to bump hard, but not blow my subs?
ignore 'peak' or 'max' wattage ratings. those are nothing but marketing b.s. only use the watts rms rating. look for an amplifier that makes around 800 watts rms at a 2 ohm load.
How many watts does a car battery produce?
A typical 12 volt (V) car battery with full charge will produce about 500 watts (W) of power. This is derived from the voltage (use 10 volts due voltage drop due to the cable) and current (I) of about 50 amps which is typical of a good battery. The formula is Watts = Volts x Amp or W = VI So W = 10 x 50 = 500 volt amperes. Keep in mind the battery will only produce this level of output for statring for a short period of time. The current will drop significantly after about 3 minutes of constant output. In your case the formula is correct. W = 12 v x 2 amp = 24 watts Good luck.
How many watts can a 8 gauge amp cable handle?
In my opinion... Bigger is almost always better, when it comes to your cabling. However, You should be fine with what you have. I believe that 8 gauge cable can handle a continuous load of around 50 amperes. Those 2 amps will draw nowhere near that kind of current.
How many watts can 1 farad support both for the amp watt and sub wattage?
1 farad means that it will support 1000 watts rms.You dont include your speakers/subwoofers when calculation a capacitor.You only worry about how many watts the amp is.
I have two speakers of 200 watts and two of 100 watts. How many watts does my amplifier need to be?
First, the power ratings of your speakers do NOT define the amount of power needed to use them. Rather, they define the maximum amount of amplifier power that the speakers can handle without being damaged.Second, if you are going to be using two pairs of speakers, the most important issue is whether or not your amplifier can handle the combined impedance of those speakers.Here are the most common impedance scenarios:Two pairs of speakers rated at 8 ohms = combined impedance of 4 ohmsTwo pairs of speakers rated at 4 ohms = combined impedance of 2 ohmsTwo pairs of speakers, one pair rated at 8 ohms and one pair rated at 4 ohms = combined impedance of 2.6 ohms.Just about any amplifier can handle an impedance of 8 ohms. Only some can handle a combined impedance of 4 ohms. Very few can handle impedances below 4 ohms.Third. the amount of power you need is defined by:a) how loud you want to play your speakers, andb) the specified sensitivity of the speakers (the higher the sensitivity, the less power you need to achieve a given loudness).Of course, your speakers must be able to handle the power you feed them and your amplifier must be able to accommodate the combined impedance of your two pairs of speakers.Note that you can easily control the amount of power going to the speakers with the volume control…therefore, you can safely use an amplifier capable of more power than the speakers can handle, just by being judicious with the volume control.Personally, I always opt for as much power as I can afford. Having a large power reserve helps to provide the best sound quality, because it allows dynamic peaks in the signal without distortion (or with less distortion).That said, in your situation and not knowing the sensitivity specifications of your speakers, your room size, your desired volume (loudness) or your listening distance, I would suggest an amp with a minimum of 60–75 watts per channel (rated via RMS method at 20Hz to 20kHz with less than 1% distortion).
