Features

940 watts (max) delivered to four channels of power

The GTO-804EZ four-channel model features 4x80 watts RMS (940 watts max). It has selectable high-pass/low-pass active crossovers and bridgeable channel pairs for total flexibility. Use this amplifier to upgrade from four channels of built-in head-unit power in an aftermarket system, as a building block in a growing system design or, by bridging both channel pairs, as a more powerful amplifier for premium component speakers.

Easy setup and adjustment of input gain

The GTO-804EZ amplifier includes an input-level switch, a setup CD with test signals and LED indicators to tell you when the setting is correct. Simply set the switch, turn the input-level knob and watch for the green light that indicates that the setup is perfect. That’s all there is to it. There’s a reason why the amplifier’s model number contains EZ. This feature significantly reduces installation time and delivers excellent results.

Wired or auto-sensing remote turn-on

JBL engineers have configured the JBL GTO-804EZ amplifier to turn on with a wired input (as in aftermarket systems) or with an auto-sensing circuit that activates whenever the amp detects an audio signal. The auto-sensing feature is helpful when you’re upgrading OEM audio systems that don’t include a remote trigger wire. It’s easily defeated by a switch when you’re using a wired remote turn-on input.

Input signal up to 15 volts (line-level or speaker-level)

The GTO-804EZ amplifier accepts a wide range of inputs up to 15 volts with line-level or speaker-level signals. Using RCA-to-bare-wire adapters included with the amplifier, you can connect to virtually any OEM or aftermarket audio system. The end result is an amplifier that works with the widest range of cars on the road.

Built-in, variable active crossovers

Active 12-decibel/octave low-pass crossovers offer variable filter points between 40Hz and 280Hz. You can select high-pass (HP) filtering, low-pass (LP) filtering or OFF. Importantly, all filter points on the adjustment dial match the silkscreened frequency points on the amplifier chassis – a feature that not all amps provide.

Built-in, variable bass boost

The GTO-804EZ provides a range of bass boost from 0 decibels to +12 decibels, centered at 45Hz. This is a useful feature for restoring some bass that may be limited by the low-frequency response of certain speakers in the system – or to enhance a particular range of bass that the speakers already produce well.

Bridgeable channel pairs

Pairs of the GTO-804EZ system amplifier’s main channels can be bridged into a single, more powerful channel. This setup is useful for flexible audio system designs in a growing system or for full-range speakers in a system that needs more power.

Automatic thermal and low-impedance protection

Amplifier protection is just like insurance; you hope you’ll never need it, but it’s sure nice to have when you do. Thermal protection keeps the GTO-804EZ system amplifier from overworking itself to the point of premature failure. Low-impedance protection keeps the amplifier safe from any speaker or wiring failures that result in short circuits.

GTO-804EZ is rated 4.0 out of 5 by 2.
Rated 5 out of 5 by from GREAT SOUND QUALITY!! I bought this to replace a rockford R400-4D. The Rockford was great as a sub amp on the back channels as my sub amp had not arrived at the time. But on my alpine spr 60 it just didn't have the airiness or crisp sound that I was used to so I bought the jbl gto804ez back on track now sounds great now especially after replacing my alpines with the infinity kappas witch are great but soon be upgrading to the jbl ms -62c as I had a chance to hear them and wow best speakers I have heard including a set of focals I heard. So basically get this amp and the jbl ms -62c and you will be in heaven!
