Affordable performance

Now you can get JBL sound quality with an entry-level price tag. Their Stage A9004 4-channel amplifier sends 90 watts RMS to each of your front and rear speakers, adding impact and clarity to your music. You can also use this versatile amp use in 3-channel mode to power a pair of speakers upfront while sending up to 140 watts to your sub.

Works in almost any vehicle

Speaker-level inputs allow this amplifier to work with most systems, even if you're keeping your factory radio. Separate high- and low-pass filters maximize your system's performance. The front and rear channels also feature a bass boost so you can make your subwoofers sound their best.

• Stage amplification has on-board circuitry to protect them from shorts, temperature, overvoltage and Undervoltage. An LED indicator is included on all four models to let you know when one of these conditions exists.
• With it becoming more and more difficult to find spacious locations for amplifier mounting, Stage has been developed in a small compact form factor to allow more location versatility.
• JBL is one of the greatest audio brands in the world.  This is not a coincidence given the arduous testing and quality control. We take our craft seriously and want every consumer to have a world-class experience that lasts and lasts.
• When Low-level inputs are used, this control adjusts the input sensitivity between 200mVrms and 5.0Vrms. When High-level inputs are used, this control adjusts the input sensitivity between 0.5Vrms and 15Vrms.
• This provides an available bass boost at 45Hz of 6dB or 12dB, serving as a great tool to optimize subwoofer and loudspeaker performance based on location and enclosure type.
• Black with deep grooves, silver silkscreen, anodized JBL badge top-center with orange end panels and bottom.
• LPF crossover controls are switchable between 0dB to 12dB at 45 Hz giving the user the ability to adjust the sound to the environment and/or application.
• Adjusts the crossover turnover frequency between 32Hz and 320Hz. (One knob for each stereo pair.)
