I have a car amplifier I want to use to amplify my home stereo system. I thought all I would need is an AC adapter to plug in the wall and connect to the amp. Maybe thats too simple (or maybe I am). This is all I want to power. In the car it connects directly to the battery. Is there not an easy way to do this??
I am using a transformer http://
The site is in swedish but you should get the idea.
It is powering a JBL 220rms amplifier hooked up to a JBL GTO 1014, and it shakes the windows and cupboards in my home when i crank up the volume.
You will need a LARGE AC adaptor with enough current to power the amp (maybe 5 to 20 amperes). The 12v power supply mentioned is the kind of thing you would need. A transformer alone will not convert ac to dc only reduce the voltage to 12v ac. A PC power supply with 12v rails will work but not be high enough in current to give you full power.
