i have a 2011 4 door wrangler and want to install 2 - e8 v.2, 8" subs in the rear floor cargo area. i measured roughly .55 cubic ft., i will pour water in it to get exact..... is there enough air volume for 2, was planning to secure a 3/4" mdf baffle to the bin, bottom mount the subs. i was hoping to be able to use the stock cover and floor mat to conceal them. i have an alpine pdx 1000.1 to power them. any support would be great. thx
