Hello, I have some questions about gel batteries. What is the difference to normal batteries that are charged with dest. water (so as far as I know lead batteries) . I only heard that with gel batteries no power fluctuations occur which constantly give off the same power, because this is very much needed in the Car Hifi range . Which are more recommended ? I have a conventional inside in the Momment but the goes slowly down the stream therefore I wanted now to What would you recommend to me? I thought of two batteries, because I have a slightly more powerful system. What do you mean a conventional front so to start and use a gel battery as a buffer in the rear would be ok? Have a 90Ah alternator and in the momment is a 60Ah battery in it. Can you also tell me how to connect the 2 batteries then? One comes into the engine compartment (just normal) and the other in the trunk (thought for the system). Is that a plus and minus cable from the battery from the engine compartment (which is supplied by the alternator) to the battery in the trunk and there plus from the engine compartment to plus in the trunk and the same with minus ? is that so correct ? and then stop from the battery in the trunk to the capacitor and then to the power stages ?
