I should start out with the disclaimer that my company is in the
consumer electronics business, specifically 12 volt entertainment
products and cellular equipment, for land based use.
You really want to avoid hooking up additional sources to your
speakers. This issue sometimes arises in the RV world, and even cars.
We do not allow our technicians to do this. In short nothing very good
can happen, bit bad things can.
Not knowing your exact equipment, it appears you have a few choices:

Well I didn't want to get to long in orig post but...
We do like the home unit, as it's already connected to all the speakers
the
boat, and I actually have large speakers with aux amp I can put on top
deck, but
it has inputs from a, VCR, DVD, a CD, the laptop, a Bose and has the
power to
drive all the speakers. Of course we usually have a gen set up and
running and
"had" a big inverter.... Inverter is T.U. and it's a good reason try
and begin
installing some power consertive systems. Our main DC power source is
32V....
Lots of that... but I only have 2 small gell-cells for instrumentation/
VHFs to
use for now. I do plan to make the 32-24 conversion (see earlier posts)
soon.
thanks John

What is the purpose of keeping the home stereo? A little more info is
needed on your objectives to give you the right answer. Are you just
buying the 12v product for the CD player? If so, get a car stereo
with amplifier outputs and use RCA cables from the CD player to the
CD input on your receiver. You can still use the volume and other
functions on the 12v unit, merely leave the home receiver on.
