The Ultimate Buying Guide for Cheap Car Amps
You want better sound in your car, but you don’t want to empty your wallet. Buying a cheap car amplifier is possible, but you need to know what to look for. This guide helps you find a great budget amp that won’t let you down.
Key Features to Look For
When shopping for an affordable amplifier, focus on these main features first. They tell you how well the amp will perform.
Power Output (RMS vs. Peak)
Always check the RMS (Root Mean Square) power. This is the real, continuous power the amp puts out. Peak power is just a temporary burst number. For good, consistent sound, choose an amp with a high RMS rating that matches your speakers’ needs. A good budget amp should offer at least 50-75 watts RMS per channel for decent volume.
Channels
How many speakers do you need to power? Budget amps usually come in 2-channel or 4-channel versions. A 4-channel amp gives you flexibility to power all four main speakers, or you can use two channels for speakers and bridge the other two for a small subwoofer.
Efficiency Class
Most cheap amps today use Class D technology. Class D amps are small and run cool. They use less power from your car battery. Look for Class D if you are worried about draining your battery or fitting the amp into a tight space.
Important Materials and Build Quality
Even cheap amps need good construction. The materials matter for how long the amp lasts.
- Heat Sinks: Look for a solid aluminum casing. Aluminum pulls heat away from the internal parts. A bigger, finned heat sink usually means the amp can handle more power without overheating.
- Wiring Terminals: Check the screw-down terminals for power and speaker wires. Cheap plastic connectors often break or loosen. Sturdy, gold-plated or nickel-plated brass terminals offer a better, more secure connection.
- Internal Components: While you cannot always see inside, read reviews about the capacitors and transistors used. Better internal parts reduce distortion when you turn the volume up high.
Factors That Improve or Reduce Quality
What makes a cheap amp sound good or bad? It often comes down to protection and design.
Quality Boosters:
Good protection circuits are vital. A quality budget amp includes protection against short circuits, overheating, and low voltage. These features save your amp and your speakers from damage.
Adjustable crossovers (high-pass and low-pass filters) also improve sound quality. They let you send only the right sounds to the right speakers, making everything sound cleaner.
Quality Reducers:
One common issue with very cheap amps is “clipping.” Clipping happens when the amp runs out of clean power and sends distorted, square-wave signals to the speakers. This ruins sound quality and can destroy tweeters. If the RMS rating seems too good to be true for the price, it probably clips easily.
Poor grounding connections caused by cheap terminals also reduce quality instantly.
User Experience and Use Cases
Who is this amp for? Cheap amps work best in specific situations.
Use Cases:
- Upgrading Factory Sound: If your factory stereo sounds weak, a small 4-channel amp can drastically improve clarity and volume without needing a huge subwoofer.
- Powering Component Speakers: These amps are perfect for powering a nice set of front component speakers that need more clean power than the head unit provides.
- Small Subwoofer Setup: A 2-channel amp bridged to a single, small (8 or 10-inch) subwoofer works well for budget bass reinforcement.
Installation is usually straightforward, but remember that even a budget amp needs proper wiring (a dedicated power wire from the battery) to perform correctly. User experience is generally positive when expectations match the price tag—expect clear, loud sound, but not concert-level volume or deep, earth-shaking bass.
10 Frequently Asked Questions (FAQ) About Cheap Car Amps
Q: Is a cheap car amp safe for my car battery?
A: Yes, if you choose a modern, efficient Class D model. Older, less efficient amps draw more power and can drain your battery faster.
Q: Can I run my speakers and a subwoofer off one cheap amp?
A: Yes, if you buy a 4-channel amp. You can bridge two channels for the sub and use the other two channels for your main speakers.
Q: What does RMS power mean for me?
A: RMS power is the real power. It tells you how loud and clear your music will play consistently without distortion.
Q: Should I use the wiring kit that comes with the amp?
A: If the kit includes very thin power wires (like 16 or 18 gauge), replace them. Undersized wires cause power loss and heat. Always use the correct gauge wire for the amp’s fuse rating.
Q: Will a cheap amp cause engine noise?
A: Sometimes. Noise usually comes from poor grounding or running the RCA (audio signal) cables too close to the power cables. Good installation prevents this.
Q: What is “clipping,” and why is it bad?
A: Clipping is when the amp tries to output more power than it can handle, sending a harsh, distorted signal that damages your speakers.
Q: Do I need a capacitor with a budget amp?
A: For most small, low-power budget amps, a capacitor is usually unnecessary. Only large, high-wattage amps truly need them to stabilize voltage.
Q: How important are adjustable crossovers?
A: They are very important. Crossovers ensure that high notes go only to your tweeters and low notes go only to your woofers or sub, resulting in much clearer sound.
Q: What is the minimum channel configuration I should buy?
A: A 4-channel amp offers the best flexibility for a basic upgrade, allowing you to power all four door speakers cleanly.
Q: Can a cheap amp power 4-ohm and 2-ohm speakers?
A: Check the specifications. Most budget amps are stable down to 2 ohms, but running at 4 ohms is easier on the amp and usually yields cleaner power.
