Exact audio system specs for base 2007 TL

Hey all,

There are numbers of references [1], [2] showing base 2007 TL's audio system as being 225 watt system, but I cannot find anywhere what this specifically means.

In other words, is 225 calculated as:

a sum of all of the speakers output, and if so, is it a peak or RMS?

or, is this a an output of an amplifier to the speakers?

Any help on getting a bit more specific information this is highly appreciated.
