Jextel Posted May 5, 2009 Report Share Posted May 5, 2009 i dont want to start a pissin match but i thought it was raduis X raduis X 3.14 example 1 18" will be 9 X 9 = 81 so then for 81 X 3.14 = 254.34 either way there close enough.. http://www.cardomain.com/ride/3042878TEAM DEADLY HERTZ "GET LOUD OR DIE TRYIN"only the loudest will survive.

cc_audio Posted May 5, 2009 Report Share Posted May 5, 2009 I think these questions depend on the price and preference. The HCCA has some crazy low end with INSANE EXCURSION something the BTL doesn't really have. (which is why I don't own one) But, as far as louder, the BTL will probabaly be louder from 35-65hertz(how much louder depends on tuning), but I bet I could get louder lower frequencies out of the HCCA's. It really up to you and the price. I would do the HCCA's but thats because I like to be unique. I'm not one to run with the crowd and BTLs are everywhere!!!! It's all gone!

vexproductions Posted May 5, 2009 Report Share Posted May 5, 2009 I personally like the HCCA. Im sure some of the replies you're gonna get are biased. (this forum is affiliated with Fi) Affiliated or not this forum is based on knowledge . Sure steve runs fi's in the truck but look at the civic . I never knew about fi until this site and i made my first purchase based on this site and the extensive amount of info now i am fi all the way due to the fact on how the subs are build and the over-all performance ... Trust me i have tried them all orion, kicker , mmats , re , ppi , .....ect Link to comment Share on other sites More sharing options...
