Out of curioisty, I have 2 14 fuses in my amp. What would happen if I took one of them out? Does that bring the watts down which would also help with the chances of blowing an altentor or something else until I get new wire and a cap? I wont be able to get 4 gauge wire and my cap for about a week or so, but I love the sound of good base and still want to run my amp to the 12's. Does that change anything?
Thanks

 

ummm i think you should just wait till you get your wire. taking a fuse out will cause the amp to not work. no fuse = open circuit

 

x2

 

One missing fuse = closed circuit.
Two missing fuses = open circuit

And what fuses do you have in there? If its 2 x 15A then your amp does NOWHERE near 2200W. It will do 360.

 

Im sorry, they are 30 fuses, two of them. I am running the amp with just one fuse and it has not had any problems yet. The reason I am getting new wires is because my truck was broken into a few months back and they stole my 1200 watt amp. Now I have a 2200 watt amp. Like I said, I am running it on 1 fuse and it works just fine, just doesnt punch as much which is fine with me, but still hits pretty good.
Lastly, what is the rule of thumb for figuring out how many watts it really is pushing when it has fuses that total 30? Do you multiply by 12? If so, why 12?
Thanks

 

The power of an electrical system (Watts) is the votage (Volts) multiplied by the current (Amps). Warning: Do not mistake the unit of measure for current (Amps) as being synonymous with an Amplifier (we won't go into all of that).

A fuse rated at 30 amps will only allow 30 amps of current (max) to pass through it before it blows. It is intended to this so that if too much current is being pulled the fuse will fry before any other internal components do. If a fuse of the recommended amperage rating is being used and it is blowing, then it usually indicates some other sort of problem; this is why you don't want to just use a larger fuse. That said, if an amp has 2 fuses rated at 30 amps, then the max current which will be allowed to pass through the amp is 60 amps. That being said, the max is not what is going to be drawn if everything is working properly; it may be close, but you don't want a fuse rated at the same level that the amp is pulling.

Therefore, if you have a max current of 60 amps multiplied by 12 volts, then the power of the amp will be 720 watts. That is, of course, assuming that the voltage of your truck's electrical system is 12 volts, which it will actually be around 14.4. So, in using that voltage, the power that your amp would be able to put out is 864 watts.

As far as working with one fuse in, I don't know enough about how amps are wired internally to know what that effects. I don't like operating any type of electrical equipment in a way other than it was designed unless I have a complete understanding of what effect it will have.

Hope this helps a little.

 

usually the fuses are wired in parallel, so instead of using a 60 amp fuse they are using 2 30 amp fuses, if you remove one you will most likely blow the other pretty quick since all the current will go through the remaining fuse, usually this is how it works, some amps are different tho, and your amp is NOT a 2200W amp, only about 850w rms based on the fuse rating

 

A quick and dirty way to check the true power output of an amplifier is to take the fuse value of the amplifier (or the sum for multiple fuses) and multiply it by 6 for class A/B amps or 10 for class D amps (higher efficiency). This is by no means an accurate way to judge power but it will tell you if your amp is even close to it's specifications. For example, if a class A/B "1,200 watt" amplifier has a fuse value of 25 amps then you can take 25*6 and get 150. So this "1,200 watt" amplifier is more in the range of 150 watts.

 

Not bad.... Hadnt thought of that.

But 50% efficiency on an A/B amp.... Its more like 35-45 (on most)

 

So then why do they claim it to be 2200? What is the point of saying it is max power 2200 watts? What happens if you exchange my 2 sets of 30 fuses for higher ones?

 

fuses have no effect on power ratings meaning that the size of the fuse does not change output. if you go to higher rated fuses when your circuitry gets hot enough to blow a fuse it wont be able to trip the fuse. itll fry your amp.

 

To get you to buy it... And you did.

Happy New Year.

 

its how shady companys get suckers like you (no offense) to buy crappy product.
