How do u install car amplifier at home?

I was given a car amplifier but i only wanted to use it at home, and i can't turn it on apparently.

I've attempted to turn it on using a transformer of DC12v.

I connected the positive terminal of the transformer into the "12+" terminal on the amplifier.

Then, i connected the negative terminal of the transformer into the remote terminal on the amplifier. The ground is already connected to a metal surface.

The amplifier's power LED did not light up, however, the protect light on the amplifier turned on.

can anybody help me turn this amplifier on for use at home? your help would be well appreciated.

don't forget about the remote wire.  It'll turn the amp on. 

My only thought is, can that transformer supply enough power to your amplifier?  Most power supplies that can are very very expensive.  I think what most ppl end up doing if they want to get an car amp in their house is get an old/or new dry cell, marine style battery and hook up a battery charger to it on trickle charge (or you could use your 12v transformer as the charger).  You could build a ventilated cabinet, etc. to house the amp and battery and truely you can make it look very nice still.

The remote turn on lead must see 12V+ for the amplifier to turn on, not ground.

wouldn't the amp need a 12- charge to keep the circuit going?

Wow, the battery idea sounds messy.  I'm a neat freak so my suggestion would be to get a 12 volt power supply from a cheap distributor, like jameco.com.  You can get a 150W, 12V DC output, 120V AC input for about $60.  Connect a few in series to get enough power or look to see if they have a bigger supply.

so I put 12V+ into the "12+" and "Remote"? what about the ground? thanks

In our country we use 220-240v AC. I'll need quite alot of those to power my 1000W one wouldn't I?

I think it will cost plenty if i buy this much transformers. What i think at the moment is that I might need a transformer that will provide at least 40amps as my amplifier has a 40amp fuse plugged into it. According to another replier, i will need a 10% overhead, which makes it 44amps minimum.

Didn't know your amp was so big.  Gets expensive with efficient power supplies

Me and a friend of mine toyed with the idea of running his two kappa perfect subs off of his Rockford 800a2 amp in his dorm room a couple years ago, but after lots of research and asking around, we determined he was gonna need one hell of a power supply.  Luckily your amp does not draw 70 amps peak current, cuz if it did you'd probably be looking at a $500 or $600 power supply, AT LEAST.  The power supply that pinchy suggested above will do you just fine and it should give your amp good clean power.

The battery idea, though possible, I would highly recommend against.  For one thing, unless it's a gel cell or sealed battery, it will give off hydrogen gas whenever it's charged.  In case you don't know, hydrogen gas is FLAMMABLE and it's also not the best thing to breathe on a regular basis.

In order to charge the batteries at the same time that they're being used to power the amp, you'd also need a battery charger that's designed to charge a battery that already has a load on it.  This would likely end up costing you a LOT more than that 40 amp power supply that pinchy suggested.  Plus the power supply isn't flammable!

Yeah, I think the supply I suggested automatically detects the input power.  The specs say

Input voltage: 100-240VAC@50-60Hz
