Can I get someone to assist me with an enclosure design for dual SP4 18s. Max dimensions are 27W x 30D x 30H. I'm currently running 2 15s and wanting to go with 18s. Power is a non issue since I'm now using two Crescendo 3.5ks. If this is possible please let me know. Looking to order the subs this week.
Also looking to go subs up, port back.
