Mono Amplifier

As the name says Mono amplifiers are single channel amps. Basically used for low-frequency applications. Since mono amplifiers are stable to 2-ohms, you can connect them safely to two 4-ohm woofers (wired in parallel). Or a DVC Subwoofer as mentioned in my earlier articles

In most car   applications, a mono amplifier is used to deliver power to a single channel subwoofer. The mono amplifier produces and as well configured to deliver low frequency at a single power signal which is ideally suited to a subwoofer. Since a mono amp is more stable in maintaining electrical current resistance when power demands increase based on impedance, two subwoofers can be wired together to a single mono amp for efficient performance

Types of Amplifiers

Several types of amplifiers available in the market based on the circuits, I am discussing few here these classifications are basically based on the circuits of the transistors used. And this articl ...

Sub Woofers

A subwoofer is a complete woofer typically between 8" and 21" in diameter and contained in a typical enclosure. Basically a subwoofer is used to reproduce a low frequency bass in the range of 20- 120  Hz. Subs are supplement to the main loudspeakers. Subwoofers are mostly made by mounting one or more woofers in a wooden container. 

There are two basic categories
1) Active Subwoofer- A subwoofer with inbuilt amplifier
2) Passive Subwoofer- A subwoofer without a inbuilt amplifier

Subwoofers comes in various enclosure designs
Bass reflex: With a port or tube in the enclosure
Infinite baffle: very large sealed enclosure
Band pass: is a two chamber enclosure, one is sealed another is with a port

Dual voice coil subwoofers

As we have seen, the integral part of a subwoofer is woofer. Normally woofers will be having a sing ...

In Dash Gps Navigation in Double Din

This article is not about how In Dash Gps Navigation works, however this article is to explain how to Integrate In Dash Gps Navigation functionality in CAR PC. Due to increasing popularity of Double Din Gadgets, all in one devices are expected to rule this niche. So a complete PC will be a right choice for In Car Entertainment i feel...

Double Din Navigation in a PC

I have used both external GPS Navigation device and my own Double din Car PC integrated with GPS receiver. I am very much inclined towards running a navigation along with other applications  in a PC.  The reason behind is
• You don’t need to obstruct your vision by putting it in the wind screen.
• Screen real estate is big and wide (7” wide screen ).
• It does not take any additional space in the dashboard.
• The GPS external receiver can be placed anywhere (I placed near in the rear ...
