yo Dude's i am trying to run my car amp of my mians but im not really shore how to do it. i have tryed using a normal charger adapter and running it off that but it will only go up to volume 10 on my head unit then will cut out i think i need mor power so tryed it with two chargers and it semmed to make a diffrence it did go a little louder but i dont really want to be using like 20 of them to get the full power of the head unit is there anyone with any ideas it would be a big help .
You could hook it up to a car battery. Your charger probably runs out of current at high power levels.

heres what you do. Go to argos. Get one of those diesel 12 car battery charger. If it's still not enough ampere, then you put it back in the box and get a refund. 🙂
Depending on how high your current draw is you could always use a comp psu, pfc preferable.

Why use a car amp at home 
A car amp is designed for 12VDC use with 2-4R load.....
3/4 of the parts in it are used for converting the 12VDC to a higher voltage to give more power.....
All these components add distortion and noise to the signal!
Why not just trade it for a home audio amplifier????

ACD, you should know full well by now that a LOT of times around here, people want to do sub-optimal things for the sole reason that the equipment in question is the only thing to hand.
Personally, I would try to use a high-powered computer power supply. Look for one for less than $10, possibly less than $5, at a second-hand store. If more current is needed still, then they can be put in parallel but it is slightly more work. Look for a power supply that
a) doesn't smell burnt; preferable to test it if the store will let you but don't expect them to.
b) has a relatively high +12V current rating. The other voltages don't concern you here.

Hi Jules!
I use a car amp in my studio (just ended up that way..). It's ultra- simple to build a power supply since a car amp has to tolerate from 12 to 16 V or so. The one I made pushes 10 A.
The circuit can use a 7812 or 7815 regulator whose output feeds the base of a simple power transistor such as 2N3055. Collector goes to the + supply, emitter is power out. (Make sure you use high-current rectifiers!)
(I might have used two T's in a parallel config., or was it two transformers? Can't remember!)
Good luck.
