5· 1 rating

Choose the Taramps HD 3000 if you need 3000W RMS on a tight budget and have the alternator and wiring to feed a 150A draw.

Pros
  • 3000W RMS for $159.95 is the cheapest route into that power class
  • Small footprint at 4.95 lb and 9.01 in long
  • Variable high-pass and low-pass crossovers cover subwoofer and full-range use
  • Works with subwoofers, mid-bass, 6x9s, drivers and super tweeters
    • Cons
    • 150.5A maximum draw demands a high-output alternator and thick wiring
    • Signal-to-noise ratio of 89 dB is well below the Kenwood's 100 dB
    • No preamp outputs and no way to strap two amps
    • Bass boost tops out at 10.5 dB

    Kenwood KAC-9105D 1-Channel Car Amp

    Choose the Kenwood KAC-9105D if you want a 100 dB signal-to-noise ratio, preamp outputs, and Dual Mono Drive strapping in a smaller chassis.

    Pros
    • 100 dB signal-to-noise ratio means less background hiss
    • Dual Mono Drive straps two amps for more output
    • Preamp outputs let you daisy-chain another amp
    • Infrasonic filter and 24 dB/octave low-pass give tighter sub control
    • 57A maximum draw is easier on a stock electrical system
    Cons
    • 900W RMS at 2 ohms is far below the Taramps' 3000W
    • Only 500W RMS at 4 ohms
    • Screw-type speaker terminals are slower to work with
    • Larger and heavier at 7.28 lb

    What reviewers say

    Taramps HD 3000 Car Audio Amplifier

    Owner feedback on the HD 3000 is limited but positive; the one rating on record is 5 out of 5, and buyers report it works with no problems so far. Taramps amps in this line are generally liked for power per dollar, with long-term durability the usual question.

    Pros
    • Delivers rated power for the money
    • Runs without issues in daily use
    • Good fit for subwoofer and bass-heavy builds
    Cons
    • Durability at full output is questioned by some owners
    • Needs a strong electrical system to hit its rating

    Questions and answers

    Which is better for a subwoofer build?
    The Taramps HD 3000, if your electrical system can supply it. It delivers 3000W RMS against the Kenwood's 900W RMS at 2 ohms. The Kenwood's 24 dB/octave low-pass and infrasonic filter give cleaner control at lower power.
    Is the Kenwood worth the extra money?
    At $189.95 versus $159.95, the Kenwood buys a 100 dB signal-to-noise ratio, preamp outputs, strapping and a 57A draw instead of 150.5A. You give up roughly two-thirds of the power.
    Which one lasts longer?
    The Kenwood's Class D design draws 57A maximum, so it runs cooler and stresses the electrical system less. The Taramps' 150.5A draw at 12.6V makes heat and voltage drop the main risks to long life.
    Can I run either amp at 1 ohm?
    The Kenwood is 1-ohm stable but regulates output to 900W there, so you gain nothing over 2 ohms. The Taramps is rated 3000W RMS and is built for low-impedance subwoofer loads.
    Which is better for a stock electrical system?
    The Kenwood. Its 57A maximum current draw fits most stock alternators. The Taramps can pull 150.5A, which usually means an upgraded alternator and wiring.
    Do either have preamp outputs?
    The Kenwood has RCA x 2 line outputs and preamp-level inputs and outputs. The Taramps lists no preamp output, so you cannot daisy-chain a second amp from it.
