In-Dash Receiver Specifications

Preamp Voltage
The preamp output rating is measured in volts (V). The higher the rating, the stronger the signal. This results in less unwanted noise being picked up.
4 volts
Display Type
The type of display on your receiver refers to the monitor that is used to display the source information such as song names, radio stations, or track times.

Dot-Matrix Text Display: A simple display which uses dots in specific illuminated color(s) to light up and form letters or numbers that are displayed on the receiver.

Graphic or Motion Display: Typically found in mid to high-end receivers and give your text information and receiver more life by adding motion, backgrounds, or multiple colors to your display. There are types of graphic displays such as 3D Graphic, Motion, and OEL (Organic Electroluminescent) displays. They can range from one color to full color displays and typically allow you to select from one of many built-in animations, background images, screensavers or other graphics to enhance your experience and add an extra bit of personality to your system. Some units also come with software that allow you to load your own customizable pictures or animations.

LCD Monitor Display: Can be as small as 2" or as large as 10". Some LCD displays are motorized for angle adjustment. LCD monitors display full motion video playback as well as your standard text such as track status, radio station information and more depending on the receiver's features.

Verified Purchase
Great quailty and looks

November 10, 2016

I would definitely recommend! The quality of the unit is excellent, wiring connections, the sealed unit, the cover is all unmatched. I use the boat in a saltwater environment that is very rough on electronics. The first unit I purchased had a volume issue that was replaced promptly without any hassles. After install I had a balance problem but after a call to technical support we corrected immediately. I would like to see a more details in the manual. The Infinity unit I have replaced 3 times in a 4 year boat will tell a little about my experience. Thumbs up JLAudio!

Why did you choose this?
Sonic Electronix Store
Eric at Auto Sound in Hurst Texas explained the product in detail, he recommended the JL MM100 for the quality and dependability. I will using in my bay boat. With the extreme heat and salt water environment the infinity radio has been replaced now for the 3rd time in 3 years. The size also was a factor, it will mount almost exactly in the same cutout.
