How many amps can i safely upgrade my alternator to?
It is a mazda 2.0 liter. Currently has a 70 amp alternator. Need to upgrade it for efficiency reasons. Wondering how many amps I can go up to
I am building an HHO generator and would like it to have 30 amps to be able to run it. Thus i would like to put about a 120 amp alternator on it. Would this be harmful
if you find one rated 120 amps make sure you have the proper voltage regulator for it or ask if it has an internal regulator

How do you calculate the amps in a capacitor if you know the voltage and number of farads?
A capacitor with 25 volts and 4,700 uf has how many amps, and how many amps would that be if I had four in parallel?
Capacitors don’t "have amps". You need to explain this better.
If you mean how much current you can draw from a charged capacitor, it depends on the load. Yes, if you had 4 in parallel, you would be able to draw more current, if the load were adjusted to call for that much current. If the load stays the same, then 4 caps would supply the same current as 1 cap, it would just last four times as long.
But the important part is that the current is NOT determined by the cap, it is determined by the load you put on it.

How many amps can i run off of my head unit?
I have a PIONEER DEH-3100UB. I am running 2 amps at the moment and was wondering if I can run more to it or if their is connections which will allow me to add more! Also, do some head units have more plug ins for more amps or do they all have the same amount?
most of the higher priced HU’s have 3 sets, front/rear/sub, but many have two or just 1. That really doesn’t determine how many amps can be connected. You can use external sound processors that will receive 1, 2, or 3 inputs and give you multiple outputs, or you can use y cables to split one output into 2, and there are also amps that have rca pass-throughs so you can connect one amp to another.

How many amps of current does a typical (600W) car subwoofer amplifier need to operate?
I want to connect some car subwoofers inside my living room. I have some 120V ac to 12V dc converters to power the amplifier. I just need to know how many output amps to which the converter should be set.
Use this.http://www.the12volt.com/ohm/page2.asp#power

How many amps should my reciprocating saw be?
I’m an average DIYer and I’m looking to buy a reciprocating saw but have no many amps would be good for just average projects around the house. Need something that can cut wood, metal and plastic.
Mine is 5 amps but they vary depending on size of motor. The saw should have a tag on it giving you this information. Mine isn’t an expensive one but has given me years of service and still going.

What are the advantages of tube bass amps to a solid-state bass amps?
I’m about to buy a new Ampeg bass amplifier. The amp i’m interested in come in a sold-state version and tube version, and are almost the same cost. I play with a Fender V-Jazz Bass, if that makes a difference. What are the advantages and disadvantages of tube amps and solid-state amps?
Advantage of tube is sound quality, nothing more. You’d have to play them both together to see the difference but for bass I wouldn’t care so much - ampeg sound sweet anyway in both forms 
Disadvantages however, Tube amps are waaaay heavier to carry, break more often and are expensive to fix. They take time to warm up properly (so you can’t plug and play instantly) and will often lose power in the tubes if you over power them which can screw gigs up. As must as I like the tone of tubes its a lot of hassle if you’re using it for typical uses such as gigging.

Where can I find the cheapest subwoofers and amps?
I am making a sculpture where I am going to use some subwoofers to make very loud, low frequency sounds (like under 60hz). I want to use about 6 subwoofers and will need three stereo amps or some sort of six channel amp. All I need are the raw speakers and amps. I will build the enclosures. What is the cheapest way to do this? Would it be hard to wire car stereo amps to run from wall outlet power?
Ebay has alot of cheaper equipment. As far as running car audio on ac power, you would need a battery charger hooked up to an actual car battery. Then you just hook it all up as you would in a car. Keep in mind that you will most likely need a head unit as well. although, You could get away with using rca connections from another source though. Make sure the amp has a low pass filter as well. good luck

How many amps should i charge my rc car batteries at?
I have a couple of rc cars and some batteries and i am looking for a new charger to charge my batteries faster. Does it matter how many amps i use to charge my batteries? My batteries are 3800 mah batteries and 3000 mah batteries, and the charger im looking at charges at 4 amps. Does it matter how many amps i charge my batteries at?
just check this website http://www.solarbatteriescharger.com

How many amps does a car cigarette lighter put out?
I have a car accessory that requires 12 volts and 2 amps. I have a plug with wire on it that fits the accessory. Can I just wire this into a cigarette lighter plug and use it or do i have to regulate the amps some how? I don’t want to blow anything up!!
2A shouldn’t be a problem. The Cig lighter is probably on a 10-20A circuit. I commonly use mine to run a 200w inverter capable of providing 1.7A on the 120v output. The input current is probably 3A or more.

How is you can have higher amps then volts?
It seems counter-intuitive to have a flow geater then your pressure. I always assumed that when you make a super conductor your volts would equal your amps as you have 0 resistance. But from what I calculated the only way to get higher amps then volts is to have fractional resistance which doesnt make much sence to me.
You can have small resistance. Take a small piece of metal wire, for example. It has a resistance of less than one ohm. If you can maintain 1 Volt across that, you will get more than 1 Amp (using Ohm’s law, V = I*R). Although doing this requires a power supply capable of supplying that much current (i.e. if you used a simple 1.5 V battery, its internal resistance will add to the overall resistance and you will not get much current).
Anyways having a "flow" greater than your "pressure" doesn’t mean anything. It’s like saying my "weight" is greater than your "height".
