Frequently Asked Questions

What is the difference between Class A/B and Class D amplifiers?

Class A/B amps offer higher quality but run hot. Class D amps are efficient, small, and run cool. Most modern car builds use Class D.

Do I need professional installation for a car amplifier?

I would suggest professional help for complex setups to ensure safety. Beginners can handle simple kits, but large systems need specific wiring and electrical upgrades.

What does ‘1 Ohm Stable’ mean?

1 Ohm stable means an amp can safely power low-impedance subwoofers. This allows for more current and power. Match your sub’s impedance to the amp’s range.

Can I use one amplifier for both speakers and a subwoofer?

Yes, a 5-channel amp can power your speakers and a subwoofer at once. This saves space and simplifies the wiring process.

Why is RMS power more important than peak power?

RMS power is the continuous power an amp can handle safely. Peak power is just a short burst. RMS is the true measure of performance.
