Now that I had a pair of Kicker C10’s under my rear seats, I needed to add some power. Looking initially for something small and simple, I browsed the Crutchfield catalog and chose a JL Audio XD300/1v2 amplifier rated at 300wx1 @2-ohms. I liked the XD Series specifically because of its small dimensions due to being a Class-D amplifier… and I didn’t want to mount the amp behind the rear seats (well, there’s no real room there anyways), so I had to pick something that fit under the driver’s seat.
Knowing the audio signal would be limited by the factory head unit, I also installed an Audio Control Epicenter Bass Processor underneath the passenger seat to get some low frequencies back. I used a PAC Line Output Converter to connect the stock Nissan head unit to the Epicenter’s inputs. With the two Kickers, I had more bass like I wanted. However at the same time, it just showed me how weak the factory main speakers were. Eventually I knew I’d upgrade the audio some more, but for the time being this was fine.
