Hello, I think that’s more of a question to the electrically enthusiastic of you 😉 So I installed a Tempra 1.p TD and a system, as power amplifier I use a Signat Rambo Limited Edition (6 channel with 2x 12V input all channels are bothered!!) Ok for the first I have “still” no capacitor for the system and for the 2nd I often have start problems with my Tempra (the battery is only 6 months old!) Jetz I thought that I would better power supply for An so that I don’t call out the discharge of both batteries, and also so that I don’t have the VOLT number and 24V!! But I would like to connect the 2nd battery so that it will be charged!! So and now another question if I have a 2nd battery I spare myself a capacitor?? Thank you already in advance Lg!
