Adding pair of tower speakers to 2020 MXZ

[Fman]

How difficult is to add a pair of tower speakers to the factory stereo system on 2020 MXZ?  Is there a specific WS amp that is built specifically for this task?  Tower come pre wired?  I have a friend who just picked up a 2020 MXZ and wants to add a pair of speakers.  I have been out of the stereo loop for awhile so not sure what Malibu and WS are doing on the 2020's.  I am assuming the Rev 10s are still available?

Any info with harnesses, amps, speakers, etc anyone can provide would be appreciated.

Thanks...

For a pair of 4 ohm tower speakers, any 2 channel amp will work, or most any 4 chnl bridged into 2 chnl mode. So quite a deep field of amp options, once the speaker selection is decided upon.

Thanks, was not sure if the new Malibu stereo head unit system required the Wetsound amps that are pre-set.  He does have all his cabin speakers and sub that are working off the Malibu stereo screen.

Just remember Revs like power.  You are better to have to much than to little when picking your amp.

The media unit is still sending out a traditional full-range low level pre-amp, but just no RCA p;lugs on the amp end, but proprietary connectors.
