Hello dear forumer, I have a question, and I bought myself a VW T4 transporter with a few colleagues. We have and want to install some electronic devices. The following basis: – The car has 2 batteries, one in the front of the engine compartment and one under the driver’s seat – Up to now radio, light, fittings and the whole standard equipment are connected to the engine compartment battery. – Up to now a 4 channel power amplifier, seat heating? and two 12V sockets are connected to the second battery. We would like to connect a 20″ TFT, an iphone docking station, and a console (probably PS3). Is that even possible, with voltage converter, if yes, an expensive one? How long do the devices last during the ride and in the state of the art etc. The three technology devices split on both batteries? or only on the second battery?
