Are there any car accessory shops that can install a 100 watt guitar amplifier. I know a car battery is 12V but is there anyway to boost up the power supply to 230V.
I Have a 4G93T 1.8 GDI in Lancer and the engine is pinking some times, I can only get 96 octane fuel, can I retard the timing by moving the crank angle sensor on the exhaust cam, or is there some other way.
