Best 6.75 Car Speakers Reviews

It may not be the coolest of purchases (ba-boom tsch), but a decent sounding pair of speakers is the cornerstone of any car audio system.

Many people who want to upgrade their car audio system have no idea where to start and often go with the most visible option first — a new aftermarket headunit. While a new headunit can enrich your in-car audio/video experience, and relatively enhance overall sound quality, it’s the speakers that are the key to making a night and day difference.

However, with so many different models and sizes on the market, each with very unique specifications (and more technical terms to describe them than a rocket manual), making your choice could prove rather difficult.

We’ve reviewed a ton of car speakers of different sizes on this site before. For the purpose of this article, we’ll be reviewing some of the best 6.75 speakers in the market.

Unlike their Full-range speakers siblings we listed above, these speakers use and advanced design to give you the optimal sound quality. Their woofers, tweeters, and external crossovers are meant to be mounted separately from each other, but they’re designed to work smoothly with one another.

Component speakers are undeniably way better than coaxial speakers, but they are a bit expensive. They’re the way to go if you’re looking for premium sound, great soundstage and imaging.

Rockford Fosgate P1675-S are some of the best 6.75 component speakers that Rockford Fosgate has to offer. Each 6-3/4″ woofer on these speakers features a responsive polypropylene cone bonded to butyl rubber surround for linear cone movement and tighter bass.

For easy installation, Rockford Fosgate has built the crossover into the woofer baskets so you don’t have to find an area to mount a separate box.

Unlike 2-way speakers which comprise of woofers that handle low frequencies, and tweeters that are dedicated to the high frequencies, these 3 way speakers employ a third driver called “super-tweeter” which is a small driver dedicated to ultra-high-frequency reproduction.

These speakers feature a sensitivity rating of 88 dB and can handle up to 80 watts of power on continuous basis (RMS). They’ll sound great when powered by your receiver, but they’ll really shine when driven by an external amplifier.
