Greetings, I'm thinking about using a car amplifier in my house. It's a 12v 600w amp. So I would need a 12v power supply that can handle a max of 50amps, just over 35amps rms. My mains are 240v 50hz. I've thought about using car batteries, but that wouldn't be all that portable and can you just hook up the battery between a crap transformer and the amp and let the battery act like a huge capacitor? I'm not really sure if the potential difference put across the battery would be put across the transformer causing it to melt. I know how I can find out but mum hates it when I burn the paint. Did I mention I'm pov? Do I need to, I'm trying to hook up a car amp in my (mums) house... That aside, I'm keen to get this sub working. And all I can find are $300 upwards... I don't have a budget, I also don't have $300. Any ideas or suggestions are welcome. Thanks.
