Car Subwoofer

Car Subwoofer, for all people is a big gadget what love in your car. If you have a vehicle, the audio system is stronger bass sound that many audio enthusiasts desire. But subwoofers need more than a low-range speaker to perform well. The enclosures they sit in can play a huge part in the subwoofer's sound. help separate the sound waves generated by the rear of the diaphragm on the speaker from that produced at the front of the speaker. Otherwise, the two sounds would create distortion, echo, and reverberation, ruining the listening experience.

So in your car can put this design:

1. Design of car subwoofer with dual chamber.

This style is designed and built for deep bass performance. Offering a dual chamber and shared slot port vent design, 5/8-inch MDF construction, making for a durable speaker. Simple to setup and easy to use, the enclosure provides a sturdy box constructed of quality materials.

2. Design of car subwoofer with screwed down terminal cups

From the provider of superior performance and sound engineering in enclosures, offers a quality 12-inch hatchback enclosure. Completely carpet enclosed, the box has screwed down terminal cups and MDF construction. The enclosure also has 1-inch speaker baffles to help control vibrations and ensure that listeners only hear what the speaker puts out, making for a cleaner sound.

TDA1566 Audio Amplifier 2x46W / 1x92W

TDA1566 general description:

The TDA1566 is a car audio power amplifier with a complementary output stage realized in BCDMOS. The TDA1566 has two Bridge Tied Load (BTL) output stages and comes in a HSOP24 or DBS27P package. The TDA1566 can be controlled with or without I2C-bus. With I2C-bus control gain settings per channel and diagnostic trigger levels can be selected. Failure conditions as well as load identification can be read with I2C-bus. The load identification detects whether the outputs of a BTL channel are connected with a DC or AC load and discriminates between a speaker load, a line driver load and an open (unconnected) load. The TDA1566 can be configured in a single BTL mode and drive a 1 Ω load. For the single BTL mode it is necessary to connect on the Printed-Circuit Board (PCB) the outputs of both BTL channels in parallel.  TDA1566 Audio Amplifier 2x46W / 1x92W
