what certifications does he has saying hes a rockford expert??

i have an 06 F-150 with 1 18" MT.

i removed my back seats and i got 6.5 cubes for now tuned to 28 hertz.

for 4 12's ported, you're looking around 8 cubes, so theres no way you're getting 4 of them back there without removing something.

so the rockford guy was right. 4 would be in too little space.
