Gen V McIntosh Amp Interface & General Questions

[A_A]

Hey guys, I've been doing some research on the McIntosh system on the 5GEN Liberty's and have a few questions.

1. When installing a double din system, is there an amp Interface available for the McIntosh amp, or do people just install a 5 channel amp and leave the centre channel out?

2. What is the 5GEN McIntosh speaker setup? Apparently it's 10 speakers, so 2 sets of splits, the centre front and the subwoofer?

Thanks guys
