About the Morel Maximo Ultra 603A MKII
For a custom-built experience
For a custom-built experience
No matter how many car audio installations I do, listening to really nice car speakers brings a certain thrill that never goes away — it's all about that moment when I hear something totally new in an old favorite song. You can count on Morel to deliver the thrills, and their Maximo Ultra Series gives you every bit of Morel's excellence and passion for sound.
3-way Maximo sound
This Morel Maximo Ultra 603A MKII component speaker system uses a 6-1/2" treated paper composite woofer, a separate 2-1/2" midrange driver, and a separate 1" soft dome tweeter to deliver impressive full-range sound. The true champ of the system is the 2-1/2" driver which takes on the dynamic sound of the midrange with gusto, so that the woofer can rumble and the tweeter can soar. This component system is designed for a system using an active 3-way crossover network, so no passive crossovers are included.
Handles up to 100 watts RMS
This system can handle up to 100 watts RMS, so you'll get the best performance powering these component speakers with an aftermarket amplifier. Morel also includes mounting solutions for ideal tweeter placement. You'll also have to custom-mount the midrange drivers in most vehicles.

- Depth: 1.38"
