Nissan Maxima Memphis audio upgrade by NVS AUDIO Linden NJ

 

This Maxima came fully loaded from the factory with Navigation and Bluetooth. The customer was happy with the factory head unit , he was just not happy with the sound of the factory Bose system. We kept the factory head unit and fed the signal into a Audison Bit Ten D . The customer loves Memphis Car audio (we are not a dealer) so the customer supplied us with 3 Memphis 10 inch subwoofers, 1 Memphis mono 500.1 and a Memphis 4 channel 75.4.Memphis 6.5 coaxial for the rear deck and 6.5 components for the front doors. We started by laying STP silver sound deadening on all the metal door skins, rear deck , trunk sides and  trunk floor. We then routed speaker plates out of 1/2 inch High Density Polyethylene (HDPE)

and used them to mount the Memphis speakers into the factory locations. We then used F.A.S.T. rings (foam speaker rings like the factory uses) to couple the speakers to the factory door panel to provide a nice tight seal between the speaker and the door panel. We upgraded the factory grounds under the hood to 4 gauge Stinger HPM series. Then we ran Stinger 4 gauge power wire from the battery to the pair of Memphis amplifiers (all power, speaker wires and distribution blocks are Stinger).

We fabricated a Amp rack out of  1 x 2 square steel to mount the amps, and processor . The amps rack was painted black then bolted to the body of the car using 1/4 20 Rivet nut inserts. We mounted the amps in the spare tire well and created a false floor with a V shaped opening in the center to show off the face of the amps, so the trunk is both beautiful and functional. We then fabricated a vented enclosure for the 3 Memphis subwoofers using our term lab software that gave us a nice flat response and played down to 30hz. The enclosure is 3/4 mdf with a fiber glass  faceplate that trims out the subs nicely and is painted to match the exterior of the car. The painted faceplate is a nice contrast to the black Suede that the customer had us wrap the entire trunk in. We also wrapped the trunk lid in the matching black suede and added a back lit Maxima logo to the center of the trunk lid.
