Compact mono amplifier for high-output subwoofer

The Taramps SMART3 is a single-channel Class D car amplifier rated at 3000 W RMS into both 1-ohm and 2-ohm loads at 12.6 VDC. It targets installers and enthusiasts driving one or two low-impedance subwoofers who need maximum power from a chassis measuring 228 x 70 x 238 mm. Buyers requiring multi-channel amplification or home-audio integration should look elsewhere.

Sustained output with variable crossovers and bass

Continuous sinusoidal draw reaches 300 A while musical peaks sit at 150 A, supported by 79 % efficiency and a 9-to-16 VDC supply window. The variable high-pass filter spans 10–90 Hz and the low-pass filter covers 90 Hz–10 kHz, both at 12 dB per octave. A 35–55 Hz bass boost adds up to 10 dB. Protection circuits guard against short circuits, voltage extremes and thermal overload during extended play.

Brazilian-built chassis with flexible signal input

The 2.6 kg aluminium body uses screw-terminal blocks for power, ground and speaker connections plus RCA inputs adjustable from 0.22 V to 4 V sensitivity. Signal-to-noise ratio exceeds 90 dB across a 10 Hz–10 kHz response. Idle current is 2.40 A. Mounting tabs on the compact frame allow secure installation in tight enclosures without specialised brackets.

Questions about this item

How hot does the SMART3 get when pushing 3000W RMS all day at 1 ohm?

At 79% efficiency the amp draws 150 A musical peaks and 300 A sinusoidal peaks, so sustained full-power use produces significant heat; its thermal protection will shut it down if cooling is insufficient.

What power and signal wiring must I already have to run the SMART3?

You need a 12.6 VDC supply capable of 150 A musical peaks, 4 AWG or larger power and ground cables, a 0.22 V–4 V RCA source, and speakers wired for a 1 or 2 ohm final load.

Will the SMART3 drive my older 4-ohm subwoofers cleanly?

Yes — at 4 ohms it delivers 2000W RMS with the same 10 Hz–10 kHz response and >90 dB signal-to-noise ratio, so legacy subs receive full bandwidth power.
