You can get a 6 CD changer that bolts into the glove box as well. That is how my 'R' arrived with me. I barely use the SC-901 3 CD changer in the head unit so removed the glove box one and the wiring. It is now sitting in a box in the garage.

I think I may also have one that mounts in the wagon trunk, and if not the unit, the mount for it.

The 98 and p2 alternators differ on mounting schemas but in theory the internals may be enough to sustain a swap. I would not personally do that as there may be other factors in play.

What would you need the extra 100A at 12-14 volts for?
I know the P2 goes from 140-180 amps, but I was aiming at the 200 amp that i thought existed for the 98 v70. I want to buy the factory AC power inverter system out of a 2012+ ford/lincoln vehicle and install it in my 98 v70. With the additional power draw, I want to eitehr put in a stronger (more CCA) battery or add a 2nd battery.

Thoughts?
It isn't the higher CCA you want with that kind of draw, it's the reserve AH. Ideally look into a battery isolator and a deep cycle marine if you want to make this a daily use of it. This way it can drain the deep cycle down hard and you still have no risk of a little/no crank situation.

Do I still need a higher output alternator? I would connect the deep cycle to the alternator, right?

If you don't use a battery isolator then it can drain both batteries down. The isolator keeps this from happening and then you hook the inverter to it. Think of the isolator as a smart switch for charging. Wouldn't hurt to get the higher capacity alternator too. It really depends on your use case, which you haven't really elaborated on...

In its simplest form, a battery isolator is a giant diode, or a check valve. The better ones have excitation for the alternator available, and potential charge priority such as charge starting battery, then charge the deep cycle afterwards. By using an isolator you won't find yourself in a condition where you can't get the car started. Often large RVs have something similar setup for the house batteries or they just let the converter handle everything - depends on the model.

hi i do not think a bigger alternator is needed just a split charge relay and a decent high ah leisure battery if you can get them i find leoch deep cycle to be very good and long lasting. i have fitted a few split charge systems on vw campers and caravans there pretty easy,fitting a large lead brick safely and not in the way may be harder!
