4. Infinity Reference REF-6522EX Shallow-Mount Coaxial Speakers: Clear Highs & All-around Fit
In our evaluation, the Infinity Reference REF-6522EX speakers stand out for their exceptional clarity in the high frequencies and their multi-purpose shallow-mount design. However, a consistent piece of owner feedback indicates that while the highs are crisp, the bass response can be somewhat understated. While capable of producing clean low notes, they may not deliver the deep, resonant thump that some listeners desire, especially without the aid of a subwoofer.
Individuals who primarily listen to bass-heavy music genres or those who prioritize powerful, room-shaking bass from their door speakers should consider supplementing these with a dedicated subwoofer or exploring other speaker options. These are best suited for listeners who appreciate articulate highs and a balanced sound profile, and for whom installation flexibility is a key concern.

- Textile dome tweeters with adjustable output levels.
- Shallow mounting depth for easy installation in tight spaces.
Pros: Bright, clear high frequencies with good detail.; High sensitivity means good performance with factory head units.; Shallow design greatly improves compatibility with various vehicles.
Cons: Bass response can be somewhat reserved compared to other models.; Some users find the highs a bit too bright without EQ adjustment.
5. Polk Audio DB652 Ultra Marine Certified Coaxial Speakers: All-Weather Performance
Based on owner feedback and the spec sheets, the Polk Audio DB652 speakers are highly praised for their solid, marine-certified construction, making them ideal for vehicles exposed to the elements. However, in our evaluation of sound quality, while they offer a clear and satisfying sound for their price and durability, they do not quite match the detailed fidelity or nuanced soundstage of dedicated audiophile-grade speakers. The sound can be described as energetic and clean, but perhaps less ‘airy’ or precise than higher-end models.
We recommend that purists or audiophiles seeking the absolute best in sound separation, imaging, and ultra-fine detail might find these speakers to be a slight compromise in pure acoustic performance compared to their more specialized counterparts. They are an excellent choice for a rugged, reliable audio solution that still sounds good, especially in trucks, convertibles, or boats, but not for those whose sole priority is uncompromised sound fidelity in a controlled environment.
- Marine certified with IP55 rating, resistant to water and UV.
- Dynamic Balance technology for distortion-free sound.
- Polypropylene UV tolerant cone with waterproof inner and outer surrounds.
Pros: Exceptional durability for harsh environments.; Good overall sound quality for the price point.; High power handling allows for sturdy output.
Cons: Sound quality, while good, isn't as refined as premium audiophile speakers.; Mounting depth can be an issue in some shallower door applications.
6. Kicker CSC65 Coaxial Speakers: Solid Performance for the Value
In our evaluation, the Kicker CSC65 speakers consistently receive positive feedback for providing a substantial upgrade over stock car audio systems, especially considering their value. A notable limitation, based on owner feedback and the spec sheets, is that while they have decent power handling, their bass response can be somewhat underwhelming when powered solely by a factory head unit. To truly achieve a full, impactful bass, these speakers often benefit significantly from an aftermarket amplifier.
Therefore, those who are looking for profound, deep bass directly from their door speakers without any further investment in amplification or a subwoofer should consider other options. While they offer clear mids and highs, and are a great value upgrade, they are best suited for users who are content with a good all-around sound or plan to integrate an amplifier for a more durable low-end performance.
- Polypropylene woofer cones for durability and responsive bass.
- PEI balanced dome tweeters for clear high-frequency output.
- Zero protrusion tweeters for easier fit behind factory grilles.

Frequently Asked Questions
What makes a speaker 'sound good'?
A speaker’s sound quality is a subjective experience, but objectively, ‘good’ sound typically refers to accurate and balanced reproduction across the entire frequency spectrum, from deep bass to clear highs, without distortion. Key factors include the materials used for the cone and tweeter, the speaker’s design (component vs. coaxial), power handling capabilities, and sensitivity, which dictates how efficiently it converts power into sound.
Do I need an amplifier for these 6.5-inch door speakers?
While many aftermarket speakers will function with a factory head unit, an external amplifier is often recommended to fully realize their potential. An amplifier provides cleaner, more consistent power, which allows the speakers to play louder without distortion, produce deeper bass, and offer better dynamic range. Speakers with lower sensitivity (below 90 dB) especially benefit from dedicated amplification.
What's the difference between component and coaxial speakers?
Component speakers separate the woofer, tweeter, and crossover into individual units, allowing for optimal placement to create a superior soundstage and imaging. Coaxial speakers, also known as full-range speakers, combine the tweeter and sometimes a mid-range driver directly into the center of the woofer cone. Coaxials are generally easier to install as direct factory replacements, while components offer enhanced sound fidelity and customization for a more involved installation.
How important is speaker sensitivity?
Speaker sensitivity is a crucial specification that indicates how efficiently a speaker converts amplifier power into sound. Measured in decibels (dB), a higher sensitivity rating (e.g., 90 dB and above) means the speaker will produce more sound output with less power. This is particularly important if you are powering your speakers with a factory head unit or a low-power amplifier, as it ensures adequate volume and clarity without needing excessive power.
Can I install these 6.5-inch speakers myself?
Many 6.5-inch coaxial speakers are designed for relatively straightforward DIY installation, especially if they are direct replacements for factory speakers. This often involves removing door panels, unscrewing old speakers, and wiring in the new ones. However, component speaker systems, or installations requiring cutting, drilling, or custom mounting, may be more complex and could benefit from professional installation to ensure optimal performance and avoid damage to your vehicle or the speakers.
