FAQ
What is the most important spec to look for in a car subwoofer? RMS power handling is the most critical spec — it tells you the continuous power the subwoofer can handle without damage, unlike peak power which is marketing fluff.
Do I need a separate amplifier for a subwoofer? Yes, most car subwoofers require an external mono amplifier to deliver enough power — factory head units typically output only modest power, far too little for a subwoofer.
What enclosure type is best for deep bass? Ported enclosures (vented boxes) provide the deepest, loudest bass by tuning the box to a specific frequency, typically in the low bass range, while sealed boxes give tighter, more accurate response.
Can I install a subwoofer myself? Yes, with basic tools like a screwdriver, wire strippers, and a multimeter, plus a wiring kit, you can install a subwoofer in a few hours — but professional installation ensures safety and performance.
How do I match a subwoofer to an amplifier? Match the RMS power rating of the subwoofer to the amplifier's output at the voice coil impedance (e.g., a subwoofer rated for a certain RMS power at a given impedance needs an amp that delivers that power at the same impedance).
What size subwoofer should I choose for my car? A 12-inch subwoofer is the most versatile — it balances deep bass and punch for most vehicles, while 10-inch subs fit tighter spaces and 15-inch subs require large enclosures for extreme output.
