This is my 2007 Mazda B4000 4x4. I have a JVC Deck and IPOD with a 10' clarion sub and amp in it and swapped out the stock speakers for some nice hertz 6x9's.   I now also have the torsion bar cranked and add a leaf in back to level it and added some 31x10.5 bf goodrich all terrain t/a tires and 16 inch fuel boost wheels with the black finish
