Is it the good choice - power supply

[johnny52]

I realy dont have any knowledge in power supply. I want to feed a 12 VDC amplifier (4x100 watts - 4 ohms) with this Omron power supply. The dealer suggested me to buy the 600 watts - 50 amp.

Can you help me to make an intelligent choice.

Thank you.

Omron S8VM 60012C - Price= $325 CAN

would you get better performance by buying two, two channel mains powered amplifiers to give you your target 100W into 4ohms?
I wouldn't pay to down convert to 12Vdc, to up convert to ~30Vac, to convert back to ~40Vdc

I'm a car audio fan and since I come on this forum I plan to install a setup in my living room.

I already have the enclosures for witch I have posted a thread.

Home audio Kompressor speakers

I need advise for the speakers choice.

My amplifier is an Orion 8004 and the head unit an Eclipse CD7000.

To power this setup I need a power supply. But as I said I dont have any knowledge about PS and I need help. I found this one (Omron) and I want to know if it is appropriate.

I'm not stick with Omron. If you have an other one to propose, let's go.
