There are basically two types of head unit for car audio available in the market. First is a SINGLE DIN and second is a DOUBLE DIN HEAD UNIT. Now you must be thinking how they are different from each other and which type of head unit for car audio you should go for? Don’t worry all the questions will be answered here in detail.
SINGLE DIN HEAD UNITS
First of all SINGLE DIN are used where there is no space for DOUBLE DIN as double din stereos are large in size and require more space to be installed than a single din stereo. They are the one of the types of head unit for car audio which can easily fit in any car very easily. Single din are cheaper than double din or touch screen head units and the face of the stereo can be easily removable if required.
TECHNICAL SPECIFICATIONS OF SINGLE DIN HEAD UNIT
They provide less power output voltage than a double din stereo. Suppose if a double din head unit is giving a full 4 VOLT output voltage then the single din head unit will be distorting at 2VOLT or even may be 1.8 VOLT. That means you have to adjust your amplifier gain much higher than you use in a double din head unit. Less output voltage does not mean that it is bad or something but for a high end music setup will require more output voltage to sound much more louder and be efficient enough for the amplifier for a great performance of the system. You get only 2 RCA OUTPUTS front and rear in SINGLE DIN AS DOUBLE DIN HAVE 3 RCA OUTPUTS FRONT REAR AND SUB WOOFER WITH HIGH POWER VOLTAGE. Single din has a disadvantage which is not good is they don’t have much equalizer options for tuning the sound. Bass boost options are also provided to increase the bass intensity.
NOTE: If you have a decent setup for you car you can surely go for single din head unit and not need to upgrade it to double din since the time you upgrade to go for a loud setup.
DOUBLE DIN HEAD UNITS
DOUBLE DIN HEAD UNITS require a large space than a single din head units and sometimes you will have to get a proper frame for them to be installed in some cars where they are attached to air conditioner vents and car dashboard kits. These are the types of head unit for car audio which require more space and more power to install in the vehicle, as they are expensive also. So they are sometimes complicated stuff to be installed but they are more advanced and looks even better than single din head units.
