Edge-driven tweeter design

Infinity employs an edge-driven design in their soft dome tweeters for a smoother, more open response and minimal distortion at high volume. Prepare for a more clearly defined soundstage as the details in your music come alive. 

Famous Plus One+ technology

This Primus polypropylene woofer delivers solid, punchy bass, thanks to Infinity's proprietary Plus One+ woofer design. Infinity extends the cone right up to the edge of the basket, giving you lots of surface area — and a bigger cone means more bass when your music needs it.

Make the most of your power

Infinity's special "true 4-ohm architecture" uses a low-impedance voice coil to safely draw extra power out of your factory radio, aftermarket stereo, or an external amplifier, so you'll get a stronger clearer sound.

Grilles are not included; the factory grilles should be suitable for most applications.

  • 6"x8" 2-way car speakers
  • Plus One+ polypropylene woofer cone with hi-roll rubber surround

Great sounding speakers. Highs and mids sound great bass not so much, but it's only a 6x8 so that's expected. I installed them in my single cab f 150 front door location.

The speakers sound good the only draw back was there were no wires or connectors supplied by Infinity and Crutchfield did not have a wiring harness for the Toyota Tacoma 2001.

Perfect replacement speakers for an affordable price. I replaced my blown factory speakers with these and they work great. Very clear sound at all volume levels. Installation was a breeze with the additional wiring harness and screws. These speakers do come with metal tabs you have to bend in order to fit the bracket but once you do that they fit perfectly. Highly recommended if you want a nice upgrade without spending too much!

Pros: Clear sound at all levels. Nice bass. Easy install.

Cons: None.

Crutchfield Customer Review (What's this?)

These Infinity Primus are a good upgrade from the factory speakers. Music is much more clean and articulate, it cleaned up all the distortion and muddiness i had when i have the music turned up. For those of you looking for window shaking bass these are NOT what you want. They do produce a clean tight mid/low bass though. They are definetly much louder than the factory speakers as well. Im running them off an aftermarket JVC deck and dont have any need for an amp. Overall im happy with the Primus and would recomend them. There are better options out there if you want to spend more money... but these were exactly what i was looking for.

Cons:

just ok

Very easy to install with excellent instructions and everything needed. Tremendous difference over factory speakers even with factory radio. I've been buying Infinity for close to 30 years and they still are the best!

Clear sound with good bass from stock deck

Crutchfield Customer Review (What's this?)

Great speakers! A definite improvement over the stock speakers in my truck (2000 Ford Ranger XLT). Great price and fast service. Easy install with all the instructions I needed. I only give 4 stars as I cannot testify to how well/long they last as I just purchased and installed them yesterday (6/14/2018). But so far I am supremely happy with them! I am still using my stock head unit but have confidence that an aftermarket unit would only make the speakers better.

Pros: Fit, sound quality, ease of installation

Cons: so far none

Crutchfield customer from Edwards, MO on 1/27/2018

Crutchfield Customer Review (What's this?)

I'm kinda jumping the gun on this review, but I think most my issues are with the head unit. I have ordered two pairs of these and with two jobs only had time to install one pair. The speakers are producing good sound. I choose these speakers cause I noticed that that had vent on the voice coil, which you see on your subs for running cooler and lasting longer. They do produce good mid bass. I've had them in for just a couple of weeks now, and already hearing some crackling from them. I'm going to get a new head unit next month,and will probably have to replace the ones I installed and be at a loss on the others. Hopefully they'll last longer.

Product Research

Features

Plus One Woofer Cones: The Plus One speaker cones offer more surface area than other speakers that fit in the same size opening. This is accomplished by using a new basket design and hi-roll surround. The result is greater bass output and an increase in efficiency.

Impedance: The Primus Series speakers feature 2.7Ω voice coils to compensate for the high in-line resistance of small gauge factory wiring and extract every watt from the factory receiver, increasing overall system output and efficiency (relative to 4-ohm speakers). The speakers also benefit from increased power when you upgrade the wire and add aftermarket amplifiers capable of powering a lower impedance load.

Mounting Applications: Infinity describes these speakers as 6x8, but they also fit many 5x7 applications. Please enter your vehicle information to confirm fit.
