cubs_fan0718 Posted May 17, 2010 Author Report Share Posted May 17, 2010 yeah imma just email them but its a 15 alpine type r LOL i got on alpines website went to subs looked at the type r 15's and there displacement which is in the specification tab says ur subs displacement is 0.123 cubic feet so basically .12 cubic ft is ur subs displacement or if u want to get exact to the T then use .123 Quote 06 Impala SSKenwood Excelon DDX593 Ampere Audio 150.4 Ampere Audio 5K1 XS D4700 (front)Mechman 320a Alt. w/ Big 3 Lots of Second Skin Damplifier Under Construction for 2017 Link to comment Share on other sites More sharing options...
Boon Posted May 18, 2010 Report Share Posted May 18, 2010 Unless you're running HUGE 45's and monstrous 3 inch all-thread you stole from a suspension bridge then I wouldn't worry about the displacement. Quote 10.x volts fo' life! Link to comment Share on other sites More sharing options...
