Rediscover your favorite songs

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 603 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.

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. The external crossover delivers an ideal blend of the highs, mids, and lows for an incredible stereo image. Morel also includes mounting solutions for ideal tweeter placement. You'll have to custom-mount the midrange drivers in most vehicles.

Features

Woofer Size Classification Note: Some manufacturers, including Morel, call this size woofer a 6½". Because it requires a larger cutout than a standard 6½" speaker, Crutchfield has traditionally referred to this size woofer as a 6¾". Please enter your vehicle information to confirm fit.

Midrange Size: The midrange drivers are not a standard size, approximately 2½" diameter. They are top mounted and have these dimensions:

  • Depth: 1.38"
  • Mounting height:
    • With Grille: 0.425"
    • Without Grille: 0.18"
  • Flange height: 0.1"
  • Cutout diameter: 2.156"
  • Frame diameter: 2.561"
  • Terminal Width: 0.11"

Tweeter Mounting Options: The tweeter can be surface or flush mounted using the included adapters. The large surface mount housing also uses the oval flush mount housing and angles the tweeters at approximately 45°. The small surface mounting housing angles the tweeters at approximately 20°.

Q
What are the crossover frequencies on the supplied crossover?
[ Tony  Aug 09, 2020 ]
1 answer
A
I found that the woofer has a LPF at 1000Hz, the midrange has an HPF at 800Hz and a LPF at 4500Hz, and the tweeter is HPF at 4500Hz

Q
what is the difference between these and the 603a's?
[ charles  May 27, 2020 ]

A
The 603's come with crossovers. The 603a's do not and you would need to use your own.
[ BRANDON  May 28, 2020 ]

Hello Charles, The 603A's require a crossover. The 603's come with a crossover. With the supplied crossover all three speakers on each side, 6.5", 2.5" and tweeter are wired to the supplied crossover (603), then the speaker wire from the amp or head unit run to the supplied crossover.
[ Thomas  May 28, 2020 ]
A
The 603a's do not come with a passive crossover. They are used with an active crossover
[ Rajah  May 28, 2020 ]
A
The normal 603 version comes with a crossover which is a device that separates the appropriate sounds sent to each component speaker. The 603a version does not come with a crossover and is meant to be used with a DSP or some other device which will limit the sound signals sent to each speaker. I can almost assure you, the standard version is more suitable for your needs. Properly configuring a system without crossovers is a complex task to say the least.
[ Matthew Kohl  May 28, 2020 ]
A
603 comes with passive crossovers. 603A does not. You would buy 603A if you had an active 3-way crossover/DSP and were separately amplifying all three channels (woofer/mid/tweet).
