Rediscover your favourite songs
No matter how many car audio installations I do, listening to high-quality car speakers brings a certain thrill that never goes away — the thrill of the moment when I hear something totally new in an old favourite song. Morel understands how you feel, and their Maximo Ultra Series delivers every bit of Morel's excellence and passion for sound at their most affordable price point.
Maximo sound
This Morel Maximo Ultra 502 MKII component speaker system pairs a treated 5-1/4" paper composite woofer and a separate 1" soft dome tweeter to deliver impressive full-range sound. This efficient system responds well even when driven by a factory radio, but it'll handle up to 90 watts RMS, so you'll get the best performance powering these component speakers with an aftermarket amplifier. The external crossover blends the highs and lows for incredible stereo imaging. Morel also includes mounting solutions for ideal tweeter placement.

Nice mid bass crystal clear highs. Handles rated rms no problem. In my opinion these are some of the better sounding components I've heard in this price range. Crutchfield's staff is very knowledgeable and eager to help.
