Kicker Head Unit/ Wired Remote Question

[Need A Vacation]

We are currently looking at a Scarab ID, and have a couple questions regarding the stock vs upgraded system.

Stock:

From pics I have seen, it looks like the same Kicker head unit is used, with a wired remote at the helm. Does anyone know if there is a remote unit that has a display? I don’t see the remote Scarab uses on Kicker’s website.

IF it is a Kicker hu, any reason another remote (transom mounted) couldn’t be added?

Upgraded:

Any idea what model amps are used?

From what I have found, it sounds like some speakers may be wired in series??? Any idea which speakers are, if so?

Can the factory amp power wire handle an additional amp, possibly a 4 channel?

General question:

It seems there is a volume control unit that can be installed inline of the rca cable, to act as a “zone volume control”. What model(s) are the best value?

While we are shopping a few other brands/ models, just trying to decide which is a better value, upgrading the base stereo package, or the factory upgraded system.

TY!!!

I did find out that the Kicker KMC 1 is the head unit for both the base ID stereo, and upgraded system, with the KRC11 being the remote. And there is not a remote unit that works with the factory head unit that has a display.

I also found the amps are the Kicker PX200.1 (sub) and the PX200.2 that is used. At least for now.
