How to Design a Complete Car-Audio System Before Buying Anything
The expensive way to build car audio is to buy exciting products one at a time and solve compatibility afterward. The reliable way begins with a system map: what the...

Building a Balanced Front Stage: Tweeters, Midranges, Midbass and Subwoofers
A system is balanced when every frequency region can reach the intended listening level without one driver screaming, another struggling and a third leaving a hole. Wattage labels do not...

Matching Subwoofers to Enclosures: Parameters, Airspace, Tuning and Intended Use
A subwoofer does not become compatible with an enclosure because its diameter fits the hole. The driver's suspension, motor, moving mass and electrical behavior determine how it reacts to the...

Matching Speakers, Crossovers and Amplifier Channels in Active and Passive Systems
A passive component system divides one amplifier channel between drivers using coils and capacitors. An active system divides frequencies in a DSP before amplification, giving each speaker band its own...

Head Unit, DSP and Amplifier Compatibility: Voltage, Inputs, Outputs and Gain Structure
The signal chain is a relay race. Every device must accept the signal handed to it and provide the format the next device expects. A connector that physically fits does...

Choosing Power Wire, Ground Wire and Fusing for an Amplifier
Power wire is selected by current, conductor material, total circuit length, installation environment and acceptable voltage loss. The number printed on an amplifier kit is not proof that the copper...

Matching an Amplifier to the Vehicle’s Electrical System: Power In Supports Power Out
An amplifier cannot create power from nothing. A physically small 3,000-watt amplifier still needs thousands of watts from the vehicle. Size, brand nationality and heatsink style do not change the...

Impedance Rise Explained: Why Rated Amplifier Power Is Not Playback Power
A subwoofer system wired to 1 ohm does not stay at exactly 1 ohm while music plays. The printed number is nominal—meaning the category on the label. The actual load...

How to Match Subwoofers With a Monoblock: Voice Coils, Final Ohm Load and RMS Power
Subwoofer matching begins before either product is purchased. The number of woofers and their voice-coil impedances determine the final load. That final load determines how much power the amplifier can...

How to Match Car Speakers With an Amplifier: RMS Power, Impedance and Headroom
Matching speakers to an amplifier is not about finding two identical numbers on two boxes. The useful match compares continuous power at the same impedance, then accounts for crossover protection,...
