I have been planning on running 2 re sx 15s in the back of my 08 frontier. I have a neighbor willing to trade me his 2 still in box re sx 18s for my 15s. Today I actually got out in the truck and did some measuring and made some templates to see how big a box I could fit without odd corners and cutouts. i came out with a box running at approx 12.5 cube. Not excluding displacement of ports or subs. How would a re sxx18 sound with only 6cu per woofer?
Planning on running 2 6" aero ports per sub. Got 2 SoundStream dtr-1700s for the subs for now.
Go with the 18s or go with the 15s and why. I dont need to know about other brands or sizes of subs. These are my options and I will be going with one or the other.
On a side note, I would like to pull off a hairtrick one day..
