How the heck do I put another battery in for my system?
So I ran into this little problem, I don't have enough power to my system! Everytime I go to turn something on in my car, headlights, turn singal etc...everything stops. I have another battery and I wanna hook it up so it doesn't drain my other battery. How do I do this myself without having to pay some professional to do so?
What amps are you running? What size is your stock alternator?
OK I'm running an Audiobahn A1500HCT amp and my alternator is 120 amp.....I'm kinda short on money so I'm trying to find the easiest and nonexpensive way to do this and was wondering if I could just hook another battery up w/o having to buy another alternator or capacitor.
When your engine is running, your electrical system (including your stereo) is being powered by your alternator. If the alternator isn't "large" enough, it can't keep up with the current demand from your amp. If it can't keep up, then the extra current needed is pulled from the battery while your alternator is still struggling to supply the current. In this case, your alternator is killing itself and won't last long anyway. You need a HO alternator.
Even if a 2nd battery did help, you'd still be losing output from your amp unless it has a regulated power supply and I don't think yours does. A HO alternator can supply 14+ volts to your amp, while a battery can only supply 12.5 volts. There's a pretty big wattage difference in the output from your amp if it's only getting 12.5 volts unless it does have a regulated power supply.
TO HOOK UP ANOTHER BATTERY - Cut your power wire leading from your battery, to your amp. Wherever you cut the power wire, is where the battery will go. Now Hook up the power wire from your battery under the hood, to the new battery (so you have two battery's in a line - a battery under the hood and your power wire leading to new battery near the amp) then from the battery near your amp hook up the remaining power wire you cut and take that directly to the amp. Then ground the battery with a ground 18" or less. Preferably a optima yellowtop
