JBL Concert A704 - 4 Channel AB Class Bridgeable Car Amplifier:
Concert sound and elegant design
Powerful Class AB Amplifier
Class AB amplifier output stage combines the advantages of the Class A amplifier and the Class B amplifier while minimizing low efficiency and distortion.
Adjustable High-Pass/Low-Pass Crossover Filter
Concert amps feature the High-Pass Filter (HPF) and the Low-Pass Filter (LPF), which allow you to adjust the frequency from 40 Hz to 400 Hz based on your own musical taste to deliver the correct music frequencies to speakers.
Auto power on feature
When using the high level signal inputs, the amplifier will automatically turn on when a DC offset is detected (>2.5 volts). When using the line-level signal inputs, the amplifier will also turn on when a +12V signal is detected from the external enable wire.
Efficient Cooling Design
The high-performance amplifiers are not only powerful but also compact and feature an efficient cooling design.
Concert sound and elegant design
JBL Concert amplifiers deliver an extraordinary sound experience and have an elegant industrial design.
Reliable performance
To deliver high-quality sound and reliable performance, the Concert amplifiers use high-quality components such as audio capacitors and power MOSFET. The amplifiers also have to undergo a rigorous testing process that unstable amplifiers would not survive. JBL freezes them, bakes them, shakes them, exposes them to ultraviolet light and tests them at full power for days.
Note: This package is for vehicle without Factory Tweeter mounts & vehicles with an aftermarket stereo with at least 2 RCA pre-outs. if you are using the factory stereo, then you would need the item below.

JBL STAGE3 527 - 5.25" 2-Way Coaxial Speakers:
Plus One™ Woofers Cones
Harman’s patented (US patent #7,548,631) Plus One™ polypropylene woofer cones provide increased cone area of up to 35% by moving the attachment point between the surround and the frame outward. The benefit of this technology is an increase in overall efficiency by up to 2dB. This provides superior output and performance when used as an upgrade to a factory system and also for a pure aftermarket system with outboard amplification.
Edge-driven dome tweeter
Edge-drive dome tweeters on 5-1/4" speakers deliver a broader and smoother high-frequency response. Engineered to Fit Close attention to fitment is paramount to the success of this speaker family. External Crossover with 0/+2dB Tweeter level control. To allow for further system tuning, a 0/+2dB tweeter level control has been providing an allowance for adjustment based on tweeter location.
Vented basket Frame design
The super-rigid vented baskets help to cool the voice coils making for a reliable speaker. Not only do these look cool but they provide a real-world benefit by wicking heat away from the motor structure almost like a fan as the cone moves through its stroke. The benefits are lower distortion at high output levels, a longer-lasting speaker and higher power handling.
Competitively Tuned
For most brands, off-the-shelf speakers and a cursory approval of frequency response curves are good enough. That’s not the case with JBL. We don’t only listen to our speakers against the competition – we voice them against each other to ensure each line has the consistent JBL sound signature that’s known and sought out by those who care about their audio. This is just part of an extensive development process undertaken by some of the best transducer
engineers in the world to provide the finest listening experience at
any price point.
