I had a 2000 2 door blazer with a fi q 18 side ported sounded great tuned to 28hz ....tried port back with a couple of 12's and with all the back gate rattle and back glass it didn't sound that great.....but if your going with sp4's I'd tune right around 28hz....them blazers will peak in the 40 to 50 hz range anyway so that should yield a better bandwidth
