This is in my car. Not sure how it works for others with the HiFi system.
HiFi system powers all the speakers with the RAM. Top HiFi HK and the B&W have the woofers powered by a Booster and all other speakers by the RAM.

Coding the RAM from HiFi to HK enables the 7-Band EQ, but in the HiFi there is only a RAM and no Booster -the 7-Band EQ only works with the Booster + RAM (Top HiFi). So the output stays HiFi (all speakers powered by the RAM), and the 7-Band EQ is only a display of the Bass and Treble adjustment of the HiFi.

This is the reason only two bands work with this coding -the Bass (Band 1) and the Treble (Band 7).
