The original sound is reproduced. Aiwei’s top four-channel power amplifier achieves car owners’ demanding hearing

Toyota RAV 4 (Rongfang) previously modified a set of three-way audio in a certain place. The system structure was passive, equipped with a ten-inch subwoofer system. The playback sound source was composed of the original car machine plus an ordinary dsp power amplifier. Due to the increasing listening requirements of car owners, our team has now been chosen for upgrades and modifications. Through the communication between the two parties, we know the owner’s listening style orientation, and we give the following modification and upgrade scheme, a fully active system: retain the previously modified Leibeqin two-channel mid-bass unit that drives three-way frequency, and install Aiwei’s flagship four-channel power amplifier to drive three-way mid-bass unit respectively. The original bass system configuration remains unchanged, equipped with Magic Cube pure dsp 8-channel audio processor. The sound field positioning of the original modification of the A-pillar did not meet the modification requirements of our store and needed to be re-modified. Here are the details of the modification process…

In the process of A-pillar positioning modification.

After the modification, start to install the mid-range unit speaker, and the inside of the cabinet should be handled properly, otherwise it will affect the density of human voice.

A-pillar modification completed renderings.

Aiwei’s flagship four-channel power amplifier is installed under the driver’s seat. As a brand’s flagship product, it meets HiFi standards in terms of appearance and sound quality. The output power reaches 160 watts per channel. While high power, the sound performance is delicate and soft, and the dynamic performance of the sound line is very balanced.

The rest of the equipment was modified under the rear seats.

The sound quality effect after modification and debugging is input by the Apple mobile phone through the original car AUX. Three-point equipment and seven-point adjustment are the truest portrayal of car audio modification.
