My buddy had an 89' Toy and he dremeled out a space below those storage compartments on that plate underneath the seats and mounted 6x9's. He put one of the amps for the 6x9's in that storage compartment on the drivers side. He had a 12 and wasn't concerned about space in his xtra cab so he just put the box on the passenger side and put the other amp in the other storage compartment.
