Replacing marine speakers in a standard 6.5-inch cutout is no problem, but if you’re cutting fresh holes to mount a pair of speakers, look for a pair like these from JL Audio. Their wide mounting flange ensures an easy installation, and they’re designed for use with a large airspace around them as opposed to pre-engineered spaces.
- No enclosure needed for mounting
- Corrosion and UV Resistant
- Solid mid bass and highs
