Ultra-compact Aluminum Chassis

JBL Apex powersports amplifiers feature an ultra-compact aluminum chassis and small footprint design to allow for installation almost anywhere.

Conformal-Coated PCB

JBL Apex powersports amplifiers are engineered to withstand harsh conditions, with fully “marinized” circuit boards to ensure flawless power delivery, year after year.

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.
