Currently I have a 10" L7 that i'm not too happy with. What would you guys recomend as an upgrade? I like sound quality yet i would like to be louder than the L7. Also, I listen to rock for the most part but sometimes rap. I have a Kenwood Excelon KAC-X812D that is supposed to put out 919W @ 2 ohms. Would this be enough to power a 12 or 15 inch FI Bl? https://ssl.perfora.net/www.ficaraudio.com/sess/utn;jsessionid=154726abc0363b0/shopdata/0015_BL/product_overview.shopscript
