Here soon, we will offer device that will any vehicle that is defaulted to a 12v electrical system to be fully regulated to, 14.4v for example, regardless of alternator system, PCM control, etc and guarantee not to light up any dash lights.. ever from our system.
It will be something ran in line with the audio system AFTER the alternator, not with or before it to prevent any confliction with the car.
They are custom-designed, manufactured Modular PCB DC-DC high KW Power supply regulators designed for 100% duty and can be custom programmed for virtually any DC IN to DC OUT application including Taramp's HV amplifiers if you want a crazy example.
They are not cheap. They will cost equal to that of an alternator Watt to Watt but are designed to last forever..
In the event of a failure(unlikely), your regulator will not be repaired, it will be replaced internally. Since the PCB is modular, you will never have to worry about lasting repair jobs. Everything is snap in, snap out and go.
We will make public announcement when they are ready for worldwide market.
