Its NICE THICK COPPER. It will be fine. The only thing that will
lessen the sound quality will be the acoustics of the showroom. If
you want to spend a bit more then buy 2.5mm 3 core flex but it isnt
neccessary. 1.5mm is rated at 15A and 100W into 8 ohms is only 3.5A
so it is plenty thick enough, added to which, the average output
level from the amp will probably be less than 20W if it is just for
background music.

AMP----SPKR1-----SPKR2-----SPKR3----SPKR4

The cable runs from one end to the other.
Speaker 2 is only connected to the 2 blues (from 1 & 3) and the
Green/Yellow (from 1)
Unless you join the incoming and outgoing brown together, the brown
wire will not make it as far as Speaker 3.

Likewise for the blues.

Speaker 1 Example
INCOMING             OUTGOING
Brown --------X---------------

SPKR

(NC) ---      -------------- G/Y

Blue----------X---------------


Speaker 2 Example
INCOMING             OUTGOING
Brown --------X---------------

G/Y ----------         (NC) --

SPKR

Blue----------X---------------

Hope that makes it clearer
