Either would be mounted in a blow through box, the port being where my stock bose sub was on the back dash of my 2001 Nissan Maxima GLE. the box would take up about 2/3 my trunk space. Ill be running either setup with an Alpine PDX 1.1000. I would like to have ur guys opinion on which u would choose, which would system would have better SQ/SPL, etc. Thanks...
