About the JBL Stadium 2

Power delivered in style

Amp technology has come a long way since a powerful 2-channel amp would take up half of your trunk. JBL's Stadium 2 two-channel car amplifier can deliver 100 watts RMS per channel to your front speakers — serious power from a compact chassis that fits easily into most vehicles. Or, you can power a subwoofer with up to 240 watts RMS from the amp's bridged channels. The variable high- and low-pass filter optimizes the amp's output to your speakers or subs, increasing the efficiency of the system.

Connectivity

You can use this amp's preamp outputs to connect to a subwoofer amp, like the Stadium 600 or Stadium 1000, so your system will have plenty of low-end punch — a remote output connection on this amp will even turn on your sub amp. The Stadium 2 can accept low- or speaker-level inputs so it'll work in almost any system, and JBL includes RCA-to-speaker wire adapters for your convenience. They've also included their proprietary electrical anti-rotational locking (E.A.R.L.) ground terminal, for a more conductive and secure ground connection for the amplifier.

Features

E.A.R.L. Terminal: An Electrical Anti-Rotational Locking (E.A.R.L.) terminal is provided for the ground wire. The terminal is designed for 4-gauge wire and requires a large crimping tool to secure. Three screws are included to attach the terminal to your vehicle's metal chassis.

Speaker-Level Input: The amp includes two speaker wire to RCA adapters, for connecting the amp to the speaker-level output of a factory radio or aftermarket head unit.

Protection Circuitry: The amplifier features protection circuitry for overheating, DC voltage on the audio output, over- or under-voltage (<9V or >16V), and short circuits. An LED lights red if the amp goes into protection mode.

Controls:

  • Gain: rotary dial; labeled min/max; range depends on how the Input Level switch is set
  • Input Level: 3-position switch:
    • Lo: line-level input only; input gain range 200mV-2V
    • Hi1: speaker-level or line-level input; no input gain range is given
    • Hi2: speaker-level input only; input gain range 2V-20V; Hi2 contains a circuit designed so the factory audio system "sees" a speaker connected to its output (some factory radios mute their output when they detect no speaker connected)
  • Crossover: 3-position switch; choose LPF (low-pass filter), HPF (high-pass filter), or Full (no crossover)
  • Frequency: rotary dial; continuously variable from 32 Hz to 320 Hz (the slope is 12 dB/octave)
  • Auto Turn-on: 2-position switch; if the source unit has no remote turn-on wire, set the switch to Auto, which turns the amplifier on when it detects a speaker level signal on the input; set to Off when connecting a remote turn-on lead

Connections:

  • Power/Ground: The power and ground set screw terminals will accept up to 4-gauge wire (although JBL appears to recommend 4-gauge in the manual, given the 30-amp fuse in the amp, we recommend 8-gauge minimum). JBL also recommends an in-line 100 amp fuse within 18" of the battery.
  • Remote Turn-On: The Remote Turn-on terminal is a 2-pin Phoenix (or Euroblock) connector that accepts up to 16-gauge wire (20-gauge recommended). There is also a remote out on the terminal to trigger a second amplifier.
  • Speaker Outputs: The speaker outputs are also set screw terminals, and will accept up to 8-gauge wire. The amplifier's minimum speaker impedance is 2Ω, 4Ω when the amp is bridged.
  • RCA Inputs: The amplifier has one pair of RCA jacks for the input, compatible with either line-level or speaker-level signals. Two speaker wire to RCA adapters are included.
  • Preamp Outputs: A pair of full range RCA outputs is provided for sending a line-level signal to a second amplifier.
