Our take on the MTX Road Thunder RT602

by Buck Pomerantz
MTX

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

An MTX Road Thunder amp puts your music up front and in your face — in a great way. You won't stop smiling when you finally hear all the musical details and and feel the awesome bass that your old system just couldn't reproduce.

2-channel workhorse
The RT602 2-channel amp will get your whole car rockin' with 60 watts RMS per channel to a set of full-range speakers or components. Or, if you choose, you can switch the amp over to mono mode to drive a sub with 180 watts RMS. You'll find the built-in high- and low-pass filters useful in matching the amp to your particular speakers or subs.

Reliable performance
When the beat gets hot during heavy play, this amp's inner works stay cool by shedding heat efficiently through a tough, extruded aluminum top cover and heatsink assembly. This Road Thunder amp features speaker-level inputs, which come in handy if you're hooking it up to a factory radio.

Features

CEA-2006 Compliant: CEA-2006 is a system of testing and measurement methods for mobile audio amplifiers. This voluntary standard advocates a uniform method for determining an amplifier's RMS power output and signal-to-noise ratio. The criteria for measuring power uses a DC input voltage of 14.4 volts and the RMS power output is measured into a 4-ohm load, with 1% or less Total Harmonic Distortion plus noise (THD+N), and at a frequency range of 20 Hz to 20,000 Hz when applicable. Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4-ohms. CEA-2006 allows consumers to compare car amplifiers and receivers on an equal basis. The MTX Road Thunder RT602 under CEA-2006 regulations is rated at 60 watts RMS x 2 channels with an 80 dBA signal to noise ratio.

2-Ohm Stable: The RT602 is capable of handling load impedances down to 2-ohms in stereo; the amplifier is rated at 90 watts RMS x 2 channels into 2-ohms with no more than 1% THD+N.

Bridgeable: The bridged output is 180 watts x 1-channels at 4-ohms.

Protection Circuits: The RT602 provides Thermal and Short-circuit protection.

Controls

Gain: The rotary gain control is continuously variable from 100 mV to 6 V.

Crossovers:

  • Mode: 3 position switch; High Pass, Low Pass, Full Range
  • High Pass: rotary control; 40 Hz to 400 Hz
  • Low Pass: rotary control; 40 Hz to 400 Hz

Connections

Power/Ground/Turn-On Connections: The RT602 features set-screw terminals for the Power, Ground and Remote turn-on lead. The Power and Ground terminals will accommodate up to 4 gauge wire, the Remote turn-on terminal will accept up to 8 gauge wire.

Speaker Connections: The amplifier is equipped with two set-screw speaker terminals. The terminals will accommodate up to 8 gauge speaker wire.

Line Level Input/Output: MTX recommends using the RCA type line-level inputs if possible. There is also a pair of RCA type line-level outputs, useful when installing additional amplifiers.

Speaker Level Input: Use the included speaker level input harnesses if the connected radio has no preamp outputs.

Fuse: The amplifier is equipped with one ATO type 30 amp fuse.
