I have about 1300 watts going to two kicker cvx 12's and I am thinking about getting another amp which would give me about 2600 watts. I want to run the 2600 watts to one Fi Audio BTL 18.. Which one do you guys believe would be louder? I know there is more cone area with the two 12's but the Fi Audio is so much better than kicker I figure it would be better. Anyway any info or incite would be greatly appreciated. Thank you.
