The Ultimate Buying Guide for Aftermarket Car Audio
Upgrading your car’s sound system can make every drive more enjoyable. Aftermarket car audio gives you better sound than your factory setup. This guide will help you choose the right parts for your vehicle.
Key Features to Look For
When shopping for new speakers, subwoofers, or amplifiers, several features matter. These details determine how loud and clear your music will sound.
Power Handling (RMS vs. Peak)
- RMS Power: This is the continuous power a speaker can handle. Look for higher RMS ratings for clear, strong sound.
- Peak Power: This is the maximum power a speaker can handle for a very short time. It’s less important than RMS.
Sensitivity (dB Rating)
Sensitivity shows how loud a speaker plays with a certain amount of power. A higher number (like 92dB) means the speaker gets louder with less power. This is great if you are using your car’s factory stereo.
Frequency Response
This range shows the lowest and highest sounds a speaker can produce. A wider range (e.g., 30Hz to 20,000Hz) means you hear deeper bass and clearer highs.
Amplifier Features
If you buy an amplifier, check the number of channels (2-channel, 4-channel) and if it has built-in crossovers. Crossovers help send the right sounds to the right speakers.
Important Materials and Build Quality
The materials used in speakers greatly affect their lifespan and sound quality. Good materials resist heat and vibration.
Speaker Cone Materials
- Polypropylene: This is a common, durable material. It handles moisture well, making it good for car doors.
- Paper (Treated): Paper cones offer a natural sound but must be treated to resist humidity.
- Mica or Carbon Fiber: These materials are light and stiff. They produce fast, accurate sound, especially in mid-range speakers.
Surrounds and Voice Coils
The surround holds the cone in place. Butyl rubber surrounds last a long time and handle temperature changes well. The voice coil, which moves the cone, should be made of durable materials like copper or aluminum wire.
Factors That Improve or Reduce Quality
The quality of your installation and the components you choose directly impact the final sound.
Quality Boosters
- Dedicated Amplifier: Adding an external amplifier gives your speakers clean, steady power. This immediately improves clarity and volume.
- Sound Dampening: Putting sound-deadening material on your doors stops rattling and vibrations. This makes the bass tighter and the overall sound cleaner.
- Component Speakers: These systems separate the woofer (for bass/mids) and the tweeter (for highs). This allows for better sound staging in the car cabin.
Quality Reducers
Using cheap, thin wires reduces power delivery and sound quality. Overpowering a small speaker with too much amplifier power will quickly cause it to blow out. Also, poor installation, like loose connections, causes buzzing and distortion.
User Experience and Use Cases
Think about how you use your car. This helps you decide where to spend your money.
Casual Listening
If you listen to music at moderate volumes, focus on high-sensitivity speakers and maybe a small four-channel amplifier. You do not need massive subwoofers.
Bass Enthusiasts (SQL/SPL)
If you want loud, deep bass, invest heavily in a high-quality subwoofer and a powerful, stable monoblock amplifier. Sound dampening becomes very important here.
Audiophiles (Sound Quality)
Audiophiles prioritize clarity and accurate sound staging. They should invest in high-quality component speakers, a multi-channel amplifier with good signal-to-noise ratio, and a digital signal processor (DSP) for fine-tuning the sound.
10 Frequently Asked Questions (FAQ) About Aftermarket Car Audio
Q: Do I need an amplifier if I only replace my speakers?
A: Not always. If your new speakers have high sensitivity (92dB or more), your factory stereo might power them well enough for moderate listening.
Q: What is the difference between coaxial and component speakers?
A: Coaxial speakers have the tweeter mounted in the center of the woofer. Component speakers keep the tweeter and woofer separate, allowing you to place the tweeter higher up for better sound direction.
Q: Will adding a subwoofer hurt my existing door speakers?
A: No. A good subwoofer handles the very low bass frequencies, which actually takes the strain off your smaller door speakers, letting them play the mid-range sounds much cleaner.
Q: What is a “head unit”?
A: The head unit is the main stereo receiver in your dashboard—the part you use to select music, change volume, and tune the radio.
Q: How much power (wattage) should my amplifier have?
A: The amplifier’s RMS wattage should closely match the RMS wattage rating of the speakers or subwoofers it is powering. Match them closely for the best performance.
Q: Is wiring quality really important?
A: Yes. Poor quality, thin wires cannot carry the necessary power. This causes voltage drops and can lead to distorted sound or damage to your amplifier.
Q: What does “impedance” (Ohms) mean for speakers?
A: Impedance is the electrical resistance. Most car speakers are 4 Ohms. Your amplifier must be rated to safely handle the total Ohm load connected to it.
Q: Can I install aftermarket audio in a leased car?
A: Yes, you can install it, but you must keep all the original parts. When the lease ends, you usually need to reinstall the factory equipment.
Q: What is “clipping” in audio?
A: Clipping happens when an amplifier is pushed too hard and sends distorted, square-wave power to the speaker. This is very damaging to tweeters and voice coils.
Q: Should I buy a new head unit first, or new speakers?
A: If your budget is limited, start with speakers and an amplifier. A good head unit offers better pre-amp signals, but better speakers will make the biggest immediate difference in sound quality.
