Speaker-level and low-level inputs let JBL Apex amplifiers integrate with just about any audio input.
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 lights & salt spray and drives them at full power for days at a time.
JBL engineers every product with a high level of design. In applications where the APEX PA 1254 will be visible, it will enhance the vehicles asthetic not take away from it.
JBL Apex powersports amplifiers feature an ultra-compact aluminm chassis and smal footprint design to allow for installation almost anywhere.
JBL Apex powersports amplifiers are engineered to withstand harsh conditions, with fully marinized" circuit boards to ensure flawless power delivery
