New Clarion m309 Head Unit is in...going to install it and the new spaker wire this afternoon. I have 100' of 12 guage wire, it's huge! I guess its just intimidating looking at it compared to the small wire in there now. Any thougts?

That is what I redid my pontoon stereo with. It sounds great.

12 gauge should be fine. You should see the 0/1 wire we ran to the amps in the car!

That's what I ran to my new tower speakers and I have 4 speakers getting 150W+ ea probably 15' run 2pr paralled to 4 speakers and it sounds great.
Here's a site that can help you calc wire size based off of load, resistance, lenght, etc + all other car audio things.
