JBL GTO-804EZ 4 Channel Amplifier connects to OEM products or aftermarket systems very easily without the hassles of adapters or setup routines. The amplifier accepts a wide range of inputs up to 15 volts with line-level or speaker-level signals, which makes it compatible with the widest range of cars on the road. The amplifier has been configured 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 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. A feature that not all amps provide is that all the filter points on the adjustment dial match the silkscreened frequency points on the amplifier chassis. The amplifier features 4 x 80 watts RMS (940 watts max). It has selectable high-pass/low-pass active crossovers and bridgeable channel pairs for complete flexibility.
The range of bass boost on offer is from 0 decibels to +12 decibels, centred 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. You can also bridge together pairs of the main channels of JBL GTO-804EZ 4 Channel Amplifier for a single, more powerful channel. This kind of a setup is suitable for flexible audio system designs in a growing system or for full-range speakers in a system that requires more power."
