Overview

If you want more output than a 6.5" speaker—and want it to look the part too—this is the move.

The Rockford Fosgate M1-8 is an 8" Color Optix marine speaker designed for louder, fuller sound in open-air environments like boats and UTVs. With built-in RGB lighting and a larger cone area, it delivers more midbass and overall output than smaller speakers.

A step up in both size and performance.

• 8" 2-way coaxial design

Quick Questions

Q: Are these louder than the M1-65?

A: Only if you want to use/customize the RGB lighting.

Q: Good for boats and UTVs?
A: That’s exactly what they’re built for.

Note
