How many mA does this amp need? It says 12V but not how many mA.

I don't know cause my subs aren't doing anything with this amp and amazon said they won't help

Whoops sorry, meant 1200 Watt amp. If each is 800 watts then you need a 1600 Watt amp. If they're 800 watts total, then you need an 800 watt amp, otherwise you risk doing some damage.

This unit will load up to 1.5amp at 10 watts-At 6v you will have more than enough current to satisfy the 500ma-I have bought several of these power supplies for a couple of different custom projects. I wire them directly into circuit boards so i cannot speak to the adapter plugs, however I can speak to the robust construction of the components. I have one that is in service for up to 12 hours at a time and it works well with not problem.

It's load at 12 volts is 3.8 watts which is less than 1/3 of an amp. You would be more than safe to drive 3 of them on 18ga wire and a 2 amp fuse.

My background is Electrical Engineering. I have one of these and it's rated at 12V 1300 mA (1.3 Amp) Voltage x Current = Power. So in this case 12 x 1.3 = 15.6 Watts. So, at 6 Volts the available current is 15.6 W / 6 Volt = 2.6 Amp or 2600 mA. So at 6 Volts it should provide up to 2,600 mA, as rated. I wouldn't be afraid to try it at 6 Volts and 1300 mA since that's about 50% of its rated load.

Hi Francis! This Amplifier is rated at 12 Watts. Merry Christmas and Happy Holidays!

That depends on the 'current ' requirements for the DVD...how many mini-amps (ma) does it need @ that voltage?

If the above poster is correct with 12 Volts and 1500 mA (1.5 Amps) the correct power would be 12 Volts times 1.5 Amps for 18 Watts......a lot more useful than 1.5.

Amps are calculated by watts over volts. So at 12v this would produce 8.3 amps. It's about two feet by four feet.

This LED lamp is rated at 1.44W. Your adapter, 110v to 12v would need a minimum 2W per lamp. This translates to 16.7 MA per lamp

This adapter is rated at .4 amps (400 ma). If your system needs 500 ma, it may work but you may lose features. I would look for an adapter that matches your rating.

usually the adapters for each device have the amp info on it-very small writing. if not, check the devices user manuals.

I have not looked at the details on the adapter, but I believe it is 12v DC. This is the usual voltage for antenna amps. Good luck. I'll look at the adapter and get back to you if it is NOT 12 VDC

Hang on while I go look. There is a tag on the bottom that states 120V A. C., 60 Hz., 1.5 A. I would have guessed it would have a higher amperage need. Additionally, there is no mention of voltage or amperage requirements in the Owner's Guide.

Mine said 500 ma, but it did not work well for me. It kept going on and off instead of staying on.

no I measured the amps. at between 130 - 160 ma. thats at 12v-13.6vdc hop it helps

So, based on Power... which is what counts: This is rated to give you 1,300 mA at 12 Volts, it should be able to provide up toward 2,600 mA at 6 Volts. Half the Voltage = Twice the Current, twice the Voltage = half the current, etc.
