Frequently Asked Questions (FAQ)
- • Why do my Alpine R2-S652 speakers sound worse than my factory speakers?
This usually happens when the speakers are underpowered by a factory head unit or installed without proper tuning. The R2-S652 requires clean amplification and proper gain settings to outperform stock speakers.
- • Do I really need an amplifier for the Alpine R2-S652?
Yes. Many users report low volume and weak midbass without an amplifier. A 75–100W RMS per channel amp is strongly recommended for full performance.
- • Why is there no bass after installing the Alpine R2-S652?
This is commonly caused by air leaks in the door, improper mounting depth, or missing sound deadening. These speakers are not designed for deep bass without subwoofer support.
- • Why do my Alpine R2-S652 speakers distort at high volume?
Distortion is usually caused by clipping from a weak amp or incorrect gain settings. Proper tuning and a clean amplifier signal will eliminate most distortion issues.
- • Why are my tweeters too loud or harsh?
This is a common complaint and is usually due to incorrect crossover placement or EQ settings. Adjusting treble levels or tweeter positioning can fix harshness.
- • Why does one side of my Alpine R2-S652 sound louder than the other?
This is typically caused by wiring polarity issues, balance/fade settings, or incorrect crossover wiring during installation.
- • Why do my speakers sound good at low volume but bad when turned up?
This usually indicates amplifier clipping or insufficient power. The R2-S652 performs best with clean headroom and proper tuning at higher volume levels.
- • Do I need sound deadening for the Alpine R2-S652?
Yes, sound deadening is highly recommended. Without it, users often experience rattling, weak midbass, and poor sound clarity.
- • Why do my Alpine R2-S652 speakers sound “flat” or boring?
This is often due to poor EQ tuning or lack of amplifier power. These speakers are designed to be dynamic and reveal their performance only when properly tuned.
- • Are the Alpine R2-S652 worth it over factory speakers?
Yes. When properly installed and powered, they deliver significantly better clarity, louder output, and improved midbass compared to factory systems.

Really an improvement on sound from the R Series before. Seems like durable speakers. Loud enough that I do not have to push the amp’s volume too much.
-
Great sounding speakers but tweeters can be harsh when the volume is cranked up
-
nice sound quality but maybe I should have went with the 3-way version. feels like the mids would be better.
