Huh? These days, any solid-state amp that costs over two bucks oughta
have an output impedance measured in tenths or even hundredths of an
ohm. If you mean that the Audi head unit is designed to drive a 2 ohm
*input* impedance, well, that's a good thing, not a bad thing, and
should pose no problem when driving 4-ohm speakers. Meanwhile, if
you're talking about the line-level output impedance, rather than the
speaker-level output, then 2 vs. 4 ohms ain't gonna mean a thing - the
input impedances of today's separate amps tend to be up in the tens of
thousands of ohms.

Re: Sound System
Obviously talking about input impedance. In practical terms what this means
is that if you fit a pair of 4 Ohm speakers, you're only just going to get
half the desired output (read volume), which is a real pain.

What's the point? - I'm assuming you already have the Gamma setup, in
which case it *really* isn't worth changing it.
