^^^ x2. I missed the 15" part. Ya 5.9cuft won't cut it for 2 15" L7's.

 

man that would sound crazy...my buddy has a similar set up...you'll go deaf lol

 

Do a BL 18" in 6 cubes/1200w.

 

or do what you want and live and learn you can put alot more that a 1000 watts into a solo I should know.

 

I am thinking of running a similar system witha Hifonics Bxi 2608 and 2 db Drive plw's 15" it says these subs ony need just over 3cubic feet ported each,I also have a Sunfire I was wondering how will my Pioneer primier Ts-D66902r's hold up to the spl of the 2 15" subs?

 

Haha model numbers and brands don't make noise. Should sound great if it's installed/set-up well. Seems like really good components. Good Luck!
