Mercury Montego Speaker FAQ

Which Mercury Montego speakers should I replace first for the biggest sound improvement?

Start with the front door panel 6 x 8 speakers. These handle most of your music's midrange frequencies and vocals, so upgrading them creates the most noticeable difference. The front speakers also benefit from better stereo imaging since you're sitting closer to them. After that, consider the rear deck lid 6 x 9 speakers - they can add significant bass response due to their larger size. The rear door speakers might be your last priority unless they're completely blown.

Can I install component speakers in my Mercury Montego's front doors?

Yes, the front door panels support component speakers along with coaxial and full-range options. Component systems typically offer better sound quality because they separate the tweeter from the woofer. You'll need to mount the tweeter separately - usually in the door panel's upper section or A-pillar. Make sure your aftermarket components match the 6 x 8 size specification. The crossover network can usually fit behind the door panel, though space might be tight in some Mercury Montego configurations.

What's the difference between coaxial and triaxial speakers for the rear deck?

Coaxial speakers have a tweeter mounted on top of the woofer - simpler design, decent sound. Triaxial adds a mid-range driver, creating three-way sound reproduction instead of two-way. The 6 x 9 rear deck location in the Mercury Montego can accommodate either type. Triaxial might give you slightly better midrange clarity, but the improvement isn't always dramatic. Coaxial speakers often provide better value and are easier to drive with factory amplification. The rear deck's acoustic properties matter more than the speaker type sometimes.

Do Mercury Montego door speakers need specific impedance ratings?

Most Mercury Montego factory systems work with 4-ohm speakers, though some configurations might use 8-ohm. Check your existing speakers for impedance markings before purchasing replacements. Using 4-ohm speakers with an 8-ohm system won't damage anything, but you might get lower volume levels. Going the other direction - 8-ohm speakers on a 4-ohm system - reduces power but won't hurt the radio. The 6 x 8 front and rear door speakers should match each other's impedance for consistent volume levels across all positions.

Will larger aftermarket speakers fit in Mercury Montego door panels?

Stick with the factory 6 x 8 size for door speakers. The mounting holes and depth clearance are specifically designed for this dimension. Trying to install 6.5-inch round speakers usually requires cutting or modification. Some 6 x 9 speakers might physically fit the door opening but could interfere with window operation or door panel reinstallation. The Mercury Montego's door architecture doesn't leave much extra space. Measure your mounting depth before buying - some aftermarket 6 x 8 speakers are deeper than factory units.
