Default Powering an IRS2092 amp

I saw this amp on eBay:

300W IRS2092 IRFI4019H IRAUDAMP7S Amplifier kit L15D on eBay (end time 04-Apr-11 15:54:47 BST)

and was wondering if it would be possible to power it with 12v batteries if I used a pair of these dc-dc converters:

DC-DC Adjustable POWER SUPPLY 10-32V to 35-60V 120W on eBay (end time 18-Apr-11 11:45:28 BST)

One for the +DC and one for -DC.

My understanding of electronics is very patchy to say the least

Any advice much appreciated!

Its hard to see if the converters outputs are isolated so you have +/0v/- voltages out.

Get in touch with the vendor and ask if the power supplies can be stacked.

No, that converter does not have an isolated output. Two seperate 12V batteries would be required.

I'm no expert, but I don't think that type of converter is suited for dynamic loads like an amplifier.

A more suitable supply would be this......

Switching boost Power Supply board DC12V to DC±32V 180W on eBay (end time 08-Apr-11 10:14:19 BST)

I have one and the output is closer to +/-36V (unloaded) since it's unregulated. You might need two of them depending on your needs.
