The JBL Concert A704 is a Class AB car amplifier that can clearly improve the sound of a factory audio system. It delivers 4 x 70 W RMS and up to 1000 W peak power, so it can drive four speakers, a setup of two speakers and a subwoofer, or two speakers in bridged mode.

Features

• adjustable high-pass filter 40–400 Hz
• high-level input for connecting to a factory radio
• automatic turn-on when a signal is detected
• RCA line inputs
• compact housing for mounting under a seat or in the trunk

Class AB

The Class AB design provides natural, clean sound, and JBL amplifiers undergo temperature and vibration tests that confirm their reliability in a car.

Installation

Installation requires a set of power cables of suitable cross-section with a fuse at the battery. The amplifier should be placed in a spot with airflow, for example under a seat or on the trunk wall.
