Frequently Asked Questions
What is the difference between component and coaxial speakers?
Component speakers separate the woofer, tweeter, and sometimes a midrange driver into individual units, allowing for better placement and soundstage. Coaxial speakers combine the tweeter and woofer into a single unit, making installation easier but typically sacrificing some imaging and detail. For best mid and high frequency performance, component systems are generally preferred, but coaxials offer a simpler upgrade path.
Do I need an amplifier for aftermarket mid and high speakers?
While some high-sensitivity speakers can be driven by a factory head unit, an amplifier is recommended to unlock their full potential. Amplifiers provide clean power, reduce distortion, and allow you to take advantage of the speakers’ power handling capabilities. Our picks like the Alpine R2-S65C and Rockford Fosgate T165-S benefit greatly from external amplification.
How important is speaker sensitivity for mid and high speakers?
Sensitivity indicates how efficiently a speaker converts power into sound. Higher sensitivity (above 90dB) means louder output with less power, making them suitable for factory stereos. Lower sensitivity speakers require more power to achieve the same volume, often necessitating an amplifier. For example, the Infinity Reference 6532EX has 95dB sensitivity, ideal for stock head units.
Can I mix and match mid and high speakers from different brands?
Yes, but it requires careful matching of impedance, sensitivity, and crossover points to ensure balanced sound. It is often easier to use a complete component set from the same brand, as the crossover is designed to blend the drivers seamlessly. If mixing, consult the specifications and consider using a digital signal processor (DSP) to tune the system.
What size speakers fit my car?
Most cars accept 6.5-inch or 6.75-inch speakers in the doors, but sizes vary by make and model. Check your vehicle’s owner manual or remove a factory speaker to measure. Adapter rings are available for some vehicles. Our guide focuses on 6.5-inch speakers, which are the most common size for mid and high frequency upgrades.
Our Verdict
After researching and comparing specifications, industry standards, and owner feedback, the Focal PS 165 F3 stands out as the top pick for its exceptional midrange clarity and overall sound quality. For those seeking a more affordable yet highly capable option, the JBL GTO609C offers excellent value and performance. Both systems deliver a significant upgrade over factory speakers, but the Focal is the choice for audiophiles willing to invest in a premium component setup.
