Just bought a 2019 Axis A20 with the base stereo option. Looking to add bow speakers and possibly a sub. Are the bow speakers pre-wired and powered by the control box? Where can I buy the OEM speakers to match the four in the main cabin? Will I need the dealer to flash anything to get them to work? Since I just bought a new boat, I'm trying to keep the budget down. I want to keep OEM functionality/beeps and not looking to go crazy loud anyway. I know I won't be able to hear it behind the boat while I ride without towers but that's fine. I live near and ride mostly on a smaller lake. Not trying to rock the whole lake with 1000watt tower speaker and be "that guy" raging tunes and sending rollers into peoples' docks. Just looking for a little more sound at the front of the boat and bass to fill out the low range while we hang out between rides. Basically trying to get to SP2 without the towers. Anticipating I will need an amp for the sub but trying to learn what I can about the current wiring setup without having to dig around and dismantle my brand new boat. Assuming the factory unit is standard 4 channels? By the way the current unit balances/fades and lack of power I'm assuming that currently the four rear speakers are being driven by the two rear channels, hoping that leaves two channels to drive the fronts?
Any advice is greatly appreciated.
