Ultra-compact Aluminum Chassis

Big Dynamic Power
Dynamic Class D output power is perfectly matched to meet the needs for your JBL car, marine and powersports products.
Full-Range Outputs and Selectable Crossovers
The Apex PA454 amplifier features selectable high-pass crossover filters, with 12dB per octave electronic crossover slopes, that are selectable from off-, 60-, 80-, 120Hz to allow for quick and easy installation.
High- and low-level inputs
Speaker-level and low-level inputs let JBL Apex amplifiers integrate with just about any audio input.
Harman Standard Reliability Testing
JBL Apex amplifiers have to go through environmental testing that would destroy other amplifiers. JBL freezes them, bakes them, shakes them, blasts them with ultraviolet light & salt spray and drives them at full power for days at a time.
JBL Industrial Design
JBL engineers every product with a high level of design. In applications where the Apex PA454 will be visible, it will enhance the vehicles aesthetic not take away from it.
