Compact four-channel amplifier

The Taramp's TA-TS400X4 delivers 400 W RMS at 2 Ohms through four channels rated at 100 W RMS each. It suits owners of door speakers, mid-range drivers, tweeters or small subwoofers in cars, golf carts or motorcycles who want a single full-range unit with bridged capability.

Fixed crossover and protection features

A factory-set low-pass filter at 90 Hz with a 12 dB/octave slope limits each channel to bass and mid-bass duties without user adjustment. Built-in short-circuit protection and an LED status indicator guard the output stage, while the Class D topology keeps idle draw to 0.8 A and musical consumption to 16.5 A at 13.8 VDC.

Wiring gauges and common pitfalls

Power leads use 11 AWG cable, speaker outputs use 15 AWG and the remote turn-on uses 18 AWG, all protected by a 20 A fuse. Installers must verify that the vehicle electrical system stays between 8 VDC and 16 VDC and that speaker loads do not drop below 2 Ohms per channel; the fixed crossover cannot be defeated for full-range use.

Questions about this item

Will the 20 A fuse ever need replacing?

The 20 A fuse protects the power circuit; replace it only if it blows due to a short or overload.

At what point does the fixed 90 Hz crossover limit full-range output?

The fixed low-pass and high-pass crossovers are set at 90 Hz with a -12 dB/octave slope, so frequencies below 90 Hz are attenuated on the high-pass channels and above 90 Hz on the low-pass channels.

How hot does the Class D chassis get during all-day use?

Idle draw is 0.8 A and musical consumption at 13.8 V is 16.5 A, so heat is moderate; the compact 4.76 x 1.93 x 5.43 in chassis relies on passive cooling with no fan.
