With 340Bhp, and looks to match the Infiniti M45 offers both performance and style in a 4-door package. My particular example is currently stock, with the exception of the addition of a K&N air filter and upgraded MB Quart Audio System. Future upgrades include Brembo Big Brake kit (for Q45), H&R Wheel spacers, to put the wheels out to the edges of the car and a custom cat-back exhaust system.
AUDIO SYSTEM
My first goal with redoing the audio system was to get better sound, but maintain a stock, or stealthy appearance. With a factory 10-inch subwoofer in the rear deck the choice to upgrade this speaker was easy. As you can see however the stock 10-incher, is hardly worthy of the subwoofer title.
Using fiberglass, I created a custom enclosure to fit below the rear deck and house the MB Quart Premium series 10-inch subwoofer.
Following the subwoofer upgrade I moved to upgrade the rest of the system. The front doors received a pair of MB Quart 6x8-inch seperates, the rear 6.5-inch seperates. The whole system was powered by MB Quart Reference amplifiers. The factory CD Changer and XM Sat. Radio were integrated into the aftermarket equipment using a JL Audio CleanSweep.
