You will need old comp power supply.
+12 V is on YELLOW wires.
-(minus) or ground is BLACK
If you have ATX power supply (that one without wires going to power switch on front - all PC now have ATX) you have to short GREEN and BLACK on main (the biggest plug to start power supply.
So use any pair black/yellow to power car amplifier.

Can you use a 12 volts 3 amp power supply on a 12 volt 500 milliamp device?
Your power supply can supply 1 A, but your device requires 2 A. So the power supply will be overloaded. So the simple answer is no.
Can you reduce 12 volt 5 amp powers supply to power a 12 volt to 150 milliamp camera?
You don't need to reduce the power supply. A device will only draw as much as it needs. A power supply of 12 volts 5 amps is the same as 12 volts 5000 mA. So you see that the power supply has more that ample capacity to operate a 150 mA camera. The thing to watch for is that both supply and camera need the same type of voltage, be it AC or DC. You can not cross that up and use AC on a DC device or vice versa.
Is it okay to use a 5 volts amp DC power supply with a device that says it needs 5 volts 2 amp?
It looks like the crucial number was left out of the question, between the words "volt ... amp DC". If the device says it needs 5 volts at 2 amp, it will run safely on any DC power supply rated at 5 volts and (2 or more) amps.
Why does we use 250ohms with power supply for the instrument calibration?
We use the 250 ohms with the power supply because the internal resistance of a DC power supply is insufficient to develop a resistance.
What happens if you connect an uncharged capacitor to your amp?
if you use a uncharged capacitor most likely your car battery will drain much faster using a uncarged capaciter will mess up your amp good power source is needed for your amp to give its maximum potential for deeper bass and no dimming
Can you use 5 volts 1.2 amp power supply on 5 volts 3.0 amp device?
No you can not. The power supply output of 1.2 amps is under sized. You would need to have a power supply of 3 amps or larger.
Can you use a 2 amp supply on a 1.5 amp WD External Drive?
If it's a "clean" power supply with the proper voltage, it shouldn't be a problem.
Can you use a car amp instead of a PA amp?
Yes, use a car CB homebase 12 volt power supply that exceeds by a couple of amperes the need of the Amp, also you want to factor in radio/cd players needs as well. I hope this may help someone. Yours The Reverend Rat +:-)
Is it okay to use a 12 volts 600 milliamp DC power supply with a device that says it needs 12 volts 1 amp?
No, 1 amp is 1000 milliamp your power supply will only deliver 600 milliamp or .6 of an amp.
Can you use a 9v-1a power supply when it calls for 9v-2000ma?
Unfortunately no, if the device calls for 2000ma you will need a 2A (amp) power supply to adequately power it.
Can you use a 1000 MA powersupply for your 1.5 amp router?
No the power supply is too small.
What kind of amp should you use to power your car speakers?
Class D
Can your 40 amp electric stove be use in your new apartment of 20 amp?
If the supply is a 20 amp supply it cannot supply a 40 amp stove, you need a bigger supply or a smaller stove.
Will a 12v 1.5 amp device work with 12v 2.5 amp replacement power supply?
No. The amperage describes the total electrical energyeither produced or consumed. Voltage just describes the potential. If the power cable or power supply are only capable of 1 amp and the device consumes 2 amps... sorry, you don't have enough electrical energy available.
Can I use a 16vac 4A power supply to power 16vac 1000ma tube amp?
Yes, 1000 ma equates to 1 amp. The 4 amp power supply will have more than enough capacity to operate any device drawing 1 amp.Just make sure that the voltages match. AC voltage of the power supply to AC voltage on the device. You can not cross voltages using a DC power supply to operate an AC device, or the other way around, an AC power supply to operate a DC powered device, even though the voltage values are the same.
Can you use a 12 volts 3 amp power supply on a 12 volt 500 milliamp device?
Your power supply can supply 1 A, but your device requires 2 A. So the power supply will be overloaded. So the simple answer is no.
Can you use 16v 4.5 amps for 16v 1.5 amps?
First, let me clarify the question: You want to use a 16V, 4.5 amp power supply to operate a device that uses 16V, 1.5 amps. That's not a problem, the larger power supply simply has the capacity of 4.5 amps, meaning that you can use anything UP TO 4.5 amps. On the other hand... if you want to try using a device that pulls 4.5 amps, using a 1.5 amp power supply... sorry, won't work out well. That would overheat the power supply and it would fail.
