The ZR360 is a 2-channel amp rated at 90 watts per channel into 4 ohms. Features include large gold-plated connections, a massive heat sink, line outputs, 2-ohm bridge capability, and Kicker’s Module Docking Port. The Module Docking Port allows the use of any of Kicker’s Active Signal Processing Modules. The ZR360 that we received for review was equipped with an active crossover module, and several of the optional modules were included as well. These modules offer a variety of signal processing capabilities, ranging from simple crossovers to remote parametric low-frequency EQ.

Performance
It’s obvious that Kicker has spent a lot of time in the competition lanes. This amp exceeds its 4-ohm rating with a 10.5-volt supply, is devoid of turn-on/off pops, and has a channel error that measures in the hundredths of a dB. It’s also built like a tank with a massive heat sink and electrical connections that look like they’ve been swiped from an industrial breaker-box and gold plated. On the functionality side, the ZR360 won’t make you coffee in the morning, but the addition of the optional plug-in modules offers impressive flexibility. The only weak link in the ZR360’s chain is its efficiency. An amp that draws better than 50 amps at 1/3 power is not likely to see its full output potential in the automotive environment.

Installation
Installing the ZR360 should be straightforward, although it may be a bit large for a passenger compartment location. The line outputs allow the amps to be daisy-chained, and Kicker even provides the necessary hex wrenches for the power and speaker connections.

Connections & Adjustments
Connections to the ZR360 include RCA inputs, RCA line outputs, the Module Docking Port, and captive-style terminal blocks for all power and speaker connections. The power connectors accept up to 4-gauge wire and the speaker connections accept up to 8-gauge. Input sensitivity is the only adjustment included on the amp itself. All other adjustments are included with and specific to the Active Signal Processing Modules.

Manual
The manual provided with this unit covers the five amps in the ZR line-up. It’s short, to the point, and doesn’t waste your time with useless information.
