alright ill try n keep this short. I will be running a pa3000db(running at 2ohms at i think 1800x1 rms) and my current car has a stock alternator output of 115 amps while the amp has a draw of (??? the damn link is broken i can't find it anywhere) i will also have an aftermarket pioneer hu not sure of the draw(it's nothing fancy so whatever a normal hu would draw), my question is will i be alright with the big 3 if not what should i do next h.o alternator 2nd battery and if i do get a 2nd batt, does it have to be the same one as under the hood. oh and kollosus 0 gauge will be all through the car i kno its a lot but im not the smartest when it comes to elcetrical output and this sort of thing however my goal is to learn so if anyone could help thanks oh and i don't think I will be able to do the big 3 my alternator is in front and my battery is in back
