I can learn a lot about the product’s design during this process. There’s an input jack for the optional PLC2 and a second jack labeled PCL-OUT that allows your installer to daisy-chain the signal to another PLC2-ready Rockford Fosgate amp.Īside from the testing and listening, one of my favorite parts of reviewing amplifiers, radios and processors is taking them apart. Last but certainly not least, the PLC2 connections are handled by RJ45 jacks. The amp has two sets of RCA input terminals: one for signal input to the amp and a second set that serves as a pass-through to let you connect another amplifier without the need for Y-cables. The set screws are accessible from the top of the amp and are concealed once the installation is complete. All the terminals use #2 Phillips screws to secure the wires. The power and ground blocks will easily accept four-AWG cables. Another terminal block for remote, power and ground connections is on the right. Four speaker terminals on the left will easily accept up to eight-AWG wires. By the way, the back of this removable panel has a large piece of foam attached to it to ensure that it doesn’t rattle as you drive or enjoy your music.Įlectrical and signal connections are made along the front edge of the amp. All the controls are accessible by removing the top panel closest to the connection panel using the provided hex-head wrench. The heatsink has been powder coated black, and the two-piece aluminum top panels have a brushed hairline finish. This weight is a significant factor as the mass of the heatsink is fundamental to keeping the amp cool so that it will continue to play when pushed hard. The P300X2 is based on a surprisingly heavy cast aluminum heat sink that includes open fins on the left and right ends. A small LED beside the sensitivity control illuminates blue when the amp starts to distort. Set-Up feature that helps your installer optimize the amp’s input signal and output capabilities. The P300X2 is equipped with the C.L.E.A.N. Given that not everyone knows when to stop cranking the volume, this is a worthwhile upgrade, even if you won’t change the subwoofer level too often. This “bass knob” includes an LED clip indicator, so you’ll know when you’ve maxed out the amplifier’s power delivery capabilities. The amp is upgradable with the optional PLC2 remote level control. Punch EQ allows your installer to dial in as much as 14 dB of signal boost at 12.5 kHz and a simultaneous 18 dB of boost at 45 Hz to add some serious kick to your music. Of course, a Punch Series amplifier needs to include the Punch EQ circuit. The filter slope is specified as being -12 dB per octave. The onboard crossover can be bypassed or set to low- or high-pass modes and adjusted from 50 to 250 Hz. The amplifier can handle as much as 12 volts RMS of signal on the RCA connections. The P300X2 is a stereo car audio amplifier rated to produce 100 watts per channel when connected to a pair of 4-ohm speakers, 150 watts per channel when driving 2-ohm speakers and can be bridged to deliver 300 watts into a single 4-ohm load. Rockford Fosgate P300X2 Features and Specifications For this Test Drive Review, I have one of the Punch P300X2 two-channel, 300-watt amplifiers in the lab to check out. The Punch name has become synonymous with the brand and currently represents their mid-tier line of solutions. Through the ’80s and ’90s, the brand grew at an exponential rate, adding subwoofers, speakers and more amplifiers that deliver fantastic performance to car audio fanatics who want their music clear and loud. If you’ve been around the car audio industry for as long as I have, you know Rockford Fosgate started in 1973 with the introduction of its first car audio amplifier.
