Frequently Asked Questions

AI
Class A/B amplifiers are generally praised for superior sound quality and fidelity, though they run hotter and are less efficient. Class D amplifiers are compact, run cooler, and provide high power output, making them ideal for driving power-hungry subwoofers.
A 2-channel amp is suitable for a pair of speakers; a 4-channel amp can power four speakers or two speakers and a bridged subwoofer; a monoblock (1-channel) is specifically designed for high-power subwoofer setups.
Extremely high-power amplifiers can put a strain on your electrical system. If you install a high-output amp, you may need to upgrade your alternator or add a capacitor to prevent voltage drops during heavy bass hits.
