Maximo Ultra 603 MKII
The Morel Maximo Ultra MKII is the latest evolution in the long-running Maximo lineage, delivering impressive sound quality at an affordable price. The updated component systems improve on their predecessors sonically, with cosmetic updates that add a clean, understated look.
The Maximo Ultra MKII components are designed to drop into factory speaker locations in most vehicles, with excellent off-axis dispersion, high resolution and crisp detail to overcome the acoustic limitations of standard speaker placement.
The 1-inch (25mm) soft dome tweeter and 2.5-inch (51mm) midrange both use Morel's EVC technology for high power handling and natural response. The 6.5-inch woofer uses a large 1-inch diameter voice coil and a high-grade ferrite magnet motor, delivering the warm, detailed bass Morel is known for.
Each model includes its own passive crossover network, bringing highs, mids and lows together and providing up to 100W of power handling. If you prefer a 2-way setup, the Maximo Ultra 602 HE MKII is a 6.5-inch 2-way component alternative from the same range.
The Maximo Ultra MKII suits a wide range of vehicles and listening tastes, offering a significant upgrade over factory audio.

About the Morel MAXIMO ULTRA 603 MKII
From our tech experts at CEN
The Morel Maximo Ultra 603 MKII is a 6.5-inch 3-way component speaker set comprising a 6.5-inch woofer, a 2.5-inch midrange and a 1-inch soft dome tweeter, with passive crossovers included. It handles 100W RMS (180W max transient) at 4 ohms and covers 50Hz to 20kHz. The set is designed to fit standard factory speaker locations in most vehicles.
Who it suits
This suits drivers wanting a genuine step up from factory audio with more midrange clarity than a 2-way set can offer. If you prefer fewer drivers and a simpler installation, the Maximo Ultra 602 MKII 2-way component is from the same range.
Our tech experts advise
Check mounting depth before ordering: the woofer needs 60mm, midrange 35mm and tweeter 20mm. If you run a DSP, Morel also offer the 603A MKII active version without passive crossovers. Fitting is priced per vehicle; see our car audio installation page for details.
