What box in a 2001 screw

supercrewsound.com will have plenty of options for you... check my gallery for pics of mine, i run the underseat box for dual 10s. my amps are mounted behind my backseat so storage back there is sortof out of the question, but i run multiple amps, if your only running one, then you could still use the other compartment for storage and such
