12 volt speaker selection box..feedback needed

i noticed most boats use external volume pots or the fader to control the tower speakers...so after after giving a lot of thought to a boat system and tower speakers....

came on the conclusion it would be very cool to have a speaker selection switch to go between the tower speakers and the boat speakers(not the sub) instead of external seperate volume controls or the fader..

this would allow the same amp/amps that power the inside boat speakers to power the tower speakers. here are the advantages...

1. use the same amps (HUGE ADVANTAGE !!!)
2. use the same volume control
3. fader(wouldnt have to use the fader)

Disadvantages:
1. cant listen to tower and the boat speakers at the same time ( you could if you used some big, big, big, amps and the switch could run a+b)

questions:

-has any one done this ???
-does anyone see any drawbacks ?
-do they make a 12v speaker selection box that can take a hugh amount of power ?

input would be appreciated.

thanks,

mike
