JBL STAGE 800BA - 8" Ported Powered Active Subwoofer:

JBL’s jaw-dropping Stage 800BA subwoofer measures less than a cubic foot and delivers an impactful performance. Inside the slot-port enclosure is a system tuned 100 watts RMS class D amplifier and 8" (200mm) subwoofer. The compact Stage 800BA will provide tight, deep bass in any car audio system. The subwoofer and amplifier have been engineered as a system to ensure great distortion-free bass even at high output levels. The rigid lightweight polypropylene woofer supplies the signature punch and clarity of JBL bass. When it’s time to show and shine, the bass EQ control is good for a 9dB boost. With the legendary JBL® logo stamped front and center on the dust cap and the oversized protection bars, you have a bass system ready to do business.

JBL Stage 800BA Lock-Port Enclosure 
JBL's slot-gate cabinet is designed and "tuned" to the optimal frequency of JBL's engineering team. The cabinet is MDF (medium-density fiberboard) to minimize resonance and undesired distortion. Lightweight, but stiff polypropylene woofer cone provides clean reproduction and superior durability in a light listening or high volume environment. 

Built-in Class D 100 Watt RMS Amplifier 
The JBL subwoofer system's built-in amplifier ensures electronics matched and optimized for woofer features and cabinet acoustics. Class D operation also means that the amplifier emits less heat and draws less power from the vehicle's electrical system. 

JBL RBC Wired Remote 
RBC Wired Remote (optional, purchased) is easily installed and allows you to remotely control the level 

Oversized Protection Bars 
The oversized protective bars give a seriously cool expression, but more importantly, they provide excellent protection for the speaker against accidental damage. 

Harman Standard Reliability Test 
JBL speakers have undergone a test process that will destroy smaller speakers. JBL freezes them, warms them, shakes them, illuminates them with ultraviolet light and drives them with full force for days to come. 

JBL at an affordable price 
This is JBL speaker and sound that has attracted audio enthusiasts for over 70 years.

What’s in the Box

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.
