Our take on the JBL GX-A602

by Buck Pomerantz
JBL

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.

Power for clarity

JBL has been designing and building sound systems for decades, so they know a thing or two about power. Their GX-A602 2-channel amplifier can send 60 watts RMS to each of your speakers, about five times the power of most factory radios. The GX-A602 includes speaker-level inputs, so it's perfect for upgrading the power in a factory system.

Versatile tone filters – versatile amp

You can also use the GX-A602 in bridged, one-channel mode to power a subwoofer with up to 170 watts RMS. A high-pass filter cleans up the sound by removing extreme low bass from small full-range speakers, allowing them to play louder and cleaner. You can also switch the filter to low-pass mode when you're driving a subwoofer, while the built-in bass boost adds some punch when you're in the mood.

Highlights:

  • 2-channel car amplifier
  • 60 watts RMS x 2 at 4 ohms (85 watts RMS x 2 at 2 ohms)
  • 170 watts RMS x 1 in bridged mode (4-ohm stable in bridged mode)
  • selectable high- or low-pass filter (80 Hz, 12 dB per octave)
  • switchable bass boost (0, 12 dB at 45 Hz)
  • preamp and speaker-level inputs
  • fuse rating: 25A x 1
  • 10-gauge power and ground leads recommended — wiring and hardware not included with amplifier
  • 7-13/16"W x 2-1/16"H x 8-1/8"D
  • warranty: 1 year
  • Our 60-day money-back guarantee
