If you have the base audio system, there is no factory-installed amplifier. The head-unit pushes ~12w RMS per channel out to 4 channels (2 front and 2 rear), to which 6 speakers are wired (2 per channel up front and 1 per channel in rear). The speakers’ impedance is a mix of 4 and 8 ohm.
If you have the Alpine upgraded factory system, there is a factory installed amp that pushes ~20w RMS per channel to 6 channels, each connected to one speaker. The channels are crossed over inside the amplifier so as to attenuate frequencies the channels’ respective speaker cannot play. All speakers are 2 ohm IIRC.
Your best approach for upgrading the speakers will depend upon which of those two systems you have. You mentioned Alpine in the OP, so I’ll assume you have the latter one. This presents some challenges to upgrading that must be kept in mind.
A) you are stuck with the factory amp and it’s non-adjustable LPF/HPF settings for any channels you want to use on it.
B) you will have to purchase the necessary adapter(s) to interface with the factory amp and bypass it to use an aftermarket amplifier while still keeping the warning chimes and steering wheel controls in tact.
C) any signal you feed the aftermarket amp will likely be incomplete (not a full signal) and require some sort of summing to be of much use.
Keeping all this in mind, I would say your planned audio upgrade should be heavy on the planned part and multi-staged on the actual upgrade part.
By that I mean it is going to require a lot of research and planning just to figure out which components you need to buy to make the upgrade happen. Once you have that list, then you can start figuring out what brand/model of each component to go with (where applicable, some pieces may only have one option).
After all that has been decided upon, you might go ahead and do the install of the equipment to make sure it all works as you expected it to. Once you have things that far, then a speaker upgrade can be done to finish off the upgrade.
IDK, you can certainly try to do everything all at once, but that’s going to be a lot of work and labor and uncertainty for one upgrade, and it just strikes me as a daunting task to hope you get right in one shot.
Or maybe the smart way forward is to buy and install the speakers first and then go after all the other hardware to finish out the upgrade. Six one; half dozen the other I suppose...
Good luck with it either way!
