Basic stereo question

[sagmanaur]

I had the unfortunate experience of having my boat broken into over the winter, and of course they stole my amplifier.
I have a stock stereo from Tige, but now that I am forced to buy a new amplifier, I want to keep expansion open for the future. At this time, I don't have money to drop on the tower speakers, but may want to add them later this year. For now I just need to get a new amplifier.
Currently I have the stock Clarion stereo with stock speakers (I believe there are 6 throughout the cabin) in my 04' 20V.

Any suggestions?

All you need is a 4 chnl full-range amp that will deliver between 50 - 100 watts RMS at 4 ohm. Marine rated is a plus not an absolute.

When you are ready to expand the system with some tower speakers, you would have needed a dedicated amp for them anyway.
