Check Some Important FAQ Of Powered Underseat Sub For Your Vehicle :
What is an underseat subwoofer?
An underseat subwoofer is a powered subwoofer for cars. It is a compact, box-like woofer with built-in amplification. It is an all-in-one device that directly plugs into a car stereo system. It powers itself and does not require a separate amplifier.
If you are planning on upgrading the bass signature of your car music system, but don’t want to get your hands dirty and are just looking for an easy remedy, you should go for an underseat powered subwoofer. It is a one-stop shop for all your bass needs. An underseat sub obviates the need to buy a sub and an amp separately, and then figure out a way to wire and mount them. It offers a complete solution as it contains both the subwoofer and the amplifier in a single consolidated unit. All you have to do is connect it to your receiver and an electrical source, and you are good to go.
How big is an underseat subwoofer?
An underseat subwoofer is a flat device with a shallow-profile cabinet. It has a space-saving design which allows it to slide into narrow spaces. A typical underseat sub is no more than 4 or 5 inches tall. It resembles a pizza box, but is thicker and more rectangular than square. The length and breadth are between 10 to 20 inches. The weight ranges from 3 to 12 kg.
An underseat sub works best with what kind of vehicles?
An underseat subwoofer is a space-efficient gadget. It is suitable for vehicles with limited interior space like hatchbacks, small sedans and pickup trucks.
Where does one mount an underseat subwoofer?
The best place to install an underseat subwoofer is under the driver’s seat or the passenger seat. If those places are taken, try the rear area if you have a small car or the trunk if you own a sedan. If you have a truck, try mounting it behind the rear bench. The idea is to keep the sub out of sight so it doesn’t get in the way of things, but is still capable of filling the car with booming bass.
How big is the sound?
An underseat sub produces a notable amount of bass. It boosts low frequencies and enhances the overall sound of the stereo system. However, it is not among the loudest automobile subwoofers. You won’t really be turning heads at a red light or rousing your neighbors as you enter your driveway. It doesn’t have a ton of power, but it’s enough to fill up the gaps in the music. For a compact sub, we think it scores really well. It gives you just the right amount of bass without overwhelming the rest of the notes, which is very important.
What should be the frequency response of an underseat subwoofer?
For a subwoofer to be able to reproduce all the low end frequencies, the ideal frequency response is 20 Hz to 200 Hz. It covers most of the audible bass frequencies and allows for a more complete reproduction of the original soundtrack.
How does the power and sensitivity of the sub impact the sound?
The power output of a subwoofer is represented in 2 ways: peak and RMS power. Peak power is the highest power a sub can put out at a given point. RMS power, also known as continuous power, is the average power a sub is capable of delivering over a period of time. Peak power is obviously higher than RMS power. When choosing an underseat subwoofer, pay attention to the RMS power as it is a more realistic representation of the power handling capacity of a subwoofer. For best results, make sure the power rating of the sub is equal to or greater than the power the stereo head-unit can supply.
A sub’s sensitivity is an indication of the amount of output it can produce. A sub with high sensitivity requires less power to produce the same amount of output as a sub with low sensitivity.
Construction of an underseat powered subwoofer :
Most underseat subs have extruded aluminum or ABS plastic enclosures. They have metal grilles to protect against knocks and impacts. The circuitry has Overload Protection, Thermal Protection, and Short Circuit Protection for trouble-free service. The cones are made of polypropylene or aluminum, and the surrounds are made of rubber. Some subs have single voice coils and some double. For a car subwoofer, a dual-voice-coil sub is better as it is easier to wire. An underseat subwoofer comes with an integrated amplifier to power the woofer driver. A wiring harness and mounting equipment are provided for setting up the system. For connectivity, the sub has low-level and high-level inputs. A wired or wireless remote may be added for ease of use while driving. Other functions include a low-pass filter, a high-pass filter, adjustable input sensitivity, and variable bass boost.
