| May 11, 2019 at 18:47 | comment | added | jonk | @ThorLancaster You make me wonder (I'm not seriously interested, though) about using the existing motor driver circuits in the car as parts for the final amplifier output stage. With the safety features of the circuit disabled, It should be able to slug speakers around just fine. Makes me wonder if any of this has already been done, too. | |

You'd have to make your own class D amplifier, but with the right design you'd be able to blow every other setup away in terms of raw power. | |

| May 11, 2019 at 6:06 | comment | added | jonk | @ThorLancaster Hmm. So what happens when a Prius Plug-In Hybrid is being used in competition? The battery voltage can be from either one 346 V system or two 207.2 V systems. Just curious. | |
| May 11, 2019 at 5:55 | comment | added | Thor Lancaster | @SolarMike Good point, many car audio competitions have classes and max voltage limits, such a system would have to be in the "unlimited" class in most competitions. | |
| May 11, 2019 at 5:45 | comment | added | Solar Mike | Do these competitions have any regulations? Such as system voltage.... | |

| May 11, 2019 at 4:31 | comment | added | Ale..chenski | Primary function of an automobile is not its audio. Audio systems use 12 V because the primary voltage in autos is 12V. Instead of having losses in a booster, you will have losses in down-converter to 12V battery, unless you re-design the entire system to run on 24 V or 48 V or whatever. Until there will be compelling economical reasons to re-design all automobiles into higher voltage, your "hybrid" proposal" doesn't make much sense. | |
