Why do you want a fourth order box in the blazer? You could do a huge slot port box tuned around 35+ and it would slam the shit out of the blazer. Hell, even a sealed box would slam hard. I had a sealed box with two pyle drivers back in 92 and My buddy put them in his blazer for a night of cruising and that shit slammed hard yo. If I was you, I would not do fourth in the blazer....
