Try using Dayton Fans.  You can find them in a McMaster-Carr Catalog.  There available in round or square, AC or DC, and with lots of accessories, guards, filters, etc.  So that you can find the fans that I'm talking about look for part number 1976K37.  In this case its a 120mm (4.69") Square Fan with 25.4mm(1") depth, 61cfm, 12VDC, .108amps 

Also remember to not oversize your fan.  I would think that you only need enough cfm to replace the air in you sub approximately every 3 to 5 minutes.

For example a sub that is 5 feet in diameter and 10 feet long would contain approximately 196 cubic feet of air.  196/3=65.3 cubic feet  196/5=39.2 cubic feet.  Based on the numbers a single fan with 61cfm should do the job.  Although personally I would use two smaller fans, this gives me some redundancy incase one fan were to fail
