I have had the solo x 12 and the 18, a 13.5 jl w7, and some higher end rf subs since I have been building. I have been out of it for a lost a year now and I finally need some bass again! My question is, what do you guys think about running 6 kicker comp 15s instead of something like 1 solo x 18 again? Pros? Cons? Any input would be great!
