FAQ
Q: What is the difference between RMS and peak power?
A: RMS (Root Mean Square) power is the continuous power an amplifier can handle safely. Peak power is the maximum power it can deliver for short bursts. Focus on the RMS rating when choosing an amplifier.
Q: What size subwoofer do I need for my car?
A: This depends on your car’s size, available space, and desired bass level. Smaller subwoofers are suitable for smaller cars or those wanting a subtle bass boost. Larger subwoofers can deliver more powerful bass but require more space and often a more powerful amplifier.
Q: Do I need a line output converter (LOC)?
A: Yes, if your factory head unit doesn’t have RCA pre-outs (line-level outputs) and you’re using an aftermarket amplifier.
Q: What gauge wire should I use for my car subwoofer amplifier?
A: Always use wire gauges recommended by the amplifier manufacturer. Thicker gauge wire (lower number, e.g., 4 gauge) is needed for high-power amplifiers to prevent voltage drop.
Q: How do I choose the right car subwoofer amplifier for my subwoofer?
A: The amplifier’s RMS power rating should match or slightly exceed your subwoofer’s RMS power handling. Consider impedance matching as well (typically 2 or 4 ohms).
Q: Can I install a car subwoofer amplifier myself?
A: While possible for some people, professional installation is often recommended, especially for high-power systems. Improper wiring can damage your car’s electrical system or the amplifier itself. Always consult professional installer if you are unsure of anything.
Q: What are the benefits of a Class D amplifier?
A: Class D amplifiers are known for their high efficiency, meaning they produce more power from less electricity. This makes them ideal for car audio systems. They are also usually more compact.
