I was wonderng if I had my ported box with the sub facing the back of the rear seats and the ports facing up wards towards the deck, if it would be as loud as having the sub facing towards the back of trunk ?? The ports will still be located facing towards the rear deck. Also if I got the snorkle ports that would make the ports face towards the rear of the trunk if it would sound any different? The equipment being used is 1 12" type R with a Alpine MRP-M500 Amp.
