Root Mean Square
Root Mean Square, or RMS, is the mathematical term for the average output of sound that the speaker can produce over time. So, for example, if the RMS of a product is 250w RMS, as it is with our Bassface SPL57.1 Coaxial 2 Way Speaker Pair, then the speakers can play your music at 250w for several hours. The higher the RMS, the more powerful the speakers.
The peak power of any speaker refers to the maximum number of watts of power that it could possibly play. So, our Kicker KS 4" (100 mm) Coaxial Speaker System has an RMS of 75w, but a peak power output of 150w. This means that it generally runs at 75w most of the time, but it has the potential to reach as high as 150w. The higher the peak power the stronger the speakers, meaning that they’ll be able to provide you with a more vibrant sound.
The sensitivity of a speaker is measured by testing how effectively a speaker is able to convert power, measured in watts, into volume, measured in decibels. The higher the rating for each of these measurements, the louder your speakers will be. Our MTX Terminator TR65S 6.5" 17cm 2 Way Component car speakers 240w have a sensitivity of 92.0dB/2.83v/1m. This means that they can deliver 92 decibels of sound at a volume amplification of 2.83 over 1 metre of space. The higher the number of decibels the more powerful your new speakers will be, allowing you to play your music louder and have a more energetic party as you drive.
All of our car door speakers can be fitted into most models of car, but the size you select will determine the aesthetic and effectiveness of your speakers. Those looking for a more discreet option should choose speakers like our 100 x 160 mm Kicker KS Coaxial Speaker System, whilst those who want everyone to know that they’ve got a stylish new way to play music should opt for something larger, like our Terminator 5.25" (130 mm) 2-way Coaxial Speaker System, which boasts a woofer diameter of 13cm and a woofer mounting depth of 50mm.
We hope that this list has helped you to select the speakers that will work best in your car. If you have any doubts or further questions,
