One of our engineer told me some tips as follows. Listed here, hope it can help someone: 1. In the car chassis fittings, the existing power-line is far from the needs of amplifier. We should use wire above 8GA. 2. Connections is very important in intallation. the ground connector and cathode should be connected firstly. 3. We must eliminate the dirt and paints on the ground connector. Loose connections will lead to function-barrier, noise and distortion.
