  • Key Specs
    • Continuous Watts x Channel @ Ohms: 125W (RMS) x 4 @ 4 ohms stereo or 175W (RMS) x 4 @ 2 ohms stereo
    • Amplifier Class: D (An amplifier's mode of operation, specifically the conditions in which its electrical current flows for the duration of an audio signal, determines its class. Each class has its strengths and weaknesses when it comes to power efficiency, levels of crossover distortion, and overall sound quality.)
    • Number Of Channels: 4
    • Bass Boost: None (Circuitry that boosts the bass response of the amplifier, improving audio reproduction enhancing the sound of low frequencies. Fixed boost means the level of bass response is preset, whereas variable boost allows the user to make adjustments.)
    • Bridgeable: true (Bridging an amplifier increases the power it supplies to the speaker(s).)
    • Low-Pass Crossover: Selectable (Devices with this function allow only audio frequencies below a chosen cut-off frequency to pass through to a speaker or sound system. A device may have a cut-off frequency predetermined by its manufacturer (fixed), multiple cut-off frequency options to choose from (selectable), or have the capability for the frequency to be configured by the user (variable).)
    • High-Pass Crossover: Selectable (Devices with this function allow only audio frequencies above a chosen cut-off frequency to pass through to a speaker or sound system. A device may have a cut-off frequency predetermined by its manufacturer (fixed), multiple cut-off frequency options to choose from (selectable), or have the capability for the frequency to be configured by the user (variable).)
    • Speaker-Level Inputs: true (Also referred to as high-level inputs. Enables the amplifier to receive a sound signal from another device that does not have RCA, or low-level, inputs.)

  • Audio
    • Number Of Channels: 4
    • Minimum Frequency Response: 0.02 hertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The minimum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
    • Maximum Frequency Response: 20 kilohertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The maximum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
    • Total Harmonic Distortion: 0.01 percent (Measurement of the harmonic sound distortion. The lower the percentage, the cleaner the sound.)
    • Signal-to-Noise Ratio (SNR): 110 decibels (The ratio of the desired signal's strength to the level of background noise. A ratio higher than 1:1, which equates to greater than 0 decibels, indicates more signal than noise.)

  • Rated 5 out of 5 stars

    Sounds so much better!!

    Purchased this by recommendation from the geek squad tech. My Memphis amp shorted out in one channel after less than two years. I bought the Memphis sure to higher power and performance, but this Stinger is noticably better in sounds quality and distortion. I am running Kicker 6x9 and 6.5 inch combos with a JBL HIDEAWAY sub in my Sequoia. It's loud and crisp. Good right bass. A must have with the factory radio is the LC7 PROCESSOR. Anyway, I can't say enough about this amp so far! I hope it lasts longer.

    High quality, 'big' sound from a tiny amp!

    This is a great amp installed by a Best Buy Audio technician. IT is very compact, so it fit behind the steering column, very crisp, clean and powerful sound from this tiny device designed for marine and powersports (aka motorcycles, boats, four wheelers, etc.) but I went for it for my Chrysler 300 anyway. It has a very cool mute/volume control button that allows you to instantly mute all speakers with a press of the button, and/or control the volume level of the rear channel with a twist of the button. Paired the AMP with four 6x9" and 2 3x5" Kicker KS series speakers and it sounds great!
