Car Speaker Installation & Speaker Upgrades

SMS Car Audio installs and upgrades car speakers for customers in Marrero, New Orleans, Harvey, Gretna, Westwego, Metairie, Kenner, Belle Chasse, and surrounding Louisiana areas.

What SMS Checks Before Recommending Speakers

Vehicle year, trim, factory speaker sizes, depth, and mounting locations.
Factory radio or factory amplifier behavior.
Whether the system needs coaxials, components, midrange, midbass, tweeters, or active channels.
Amplifier power, crossover protection, DSP tuning, and wiring needs.
Door treatment, adapter rings, sealing, grille clearance, and serviceability.

Speaker Fitment Is More Than Size

A speaker may be listed as the right size but still need adapters, trimming, depth checks, polarity checks, or different system planning. SMS looks at how the speaker will mount, how much power it will see, and whether it matches the customer’s goal.

Active front-stage systems with DSP tuning.
