What is the best cd deck/hu for my system?

Question

I was wondering what would be the the best cd deck/ head unit for my system. Right now i have an old eclipse cd deck and i wanted to know if i upgraded my deck if it would make my system louder. I heard that pioneer makes good decks for subwoofers. I have a kenwood 1800 watt amp and two kicker cvr 12" with about 1 sf3 in a sealed box. I was also wondering if a bigger box would help and I'm thinking about adding a third sub. I heard adding the same brand and type of sub is louder than using different brands. Right now I also have only 4 gauge wire for ground and power. Any answers are helpful.

Thank you
