Silver Member Username: Nnnnick_bNc Usa Post Number: 331 Registered: Jan-05 | Your battery can only generate those numbers for a few seconds at a time(starting the car) or it will over heat. Also the battery puts out 12 volts. Most stock alts put out 13.8, and most after market alts put out 14.4 to 15.8. Your alt is too small for even one amp. Your alternator will always be charging your battery if the engine is running. as long as its voltage doesnt drop below 12 volts then it is charging the batt. In your situation i would look at getting something in the 175 amp range. Also, you will want to eventually upgrade your power and ground wires for your alt to battery. |

Bronze Member Username: LowdoseSt. Louis, Mo Post Number: 23 Registered: Apr-05 | $150 to $250 depending on size make and model of car. Most of the ones I have been looking into anyway. That was for a 150 amp alts. 1 may have been 200 amp. There is another thread about this same topic that has links to some good sites for them. https://www.ecoustics.com/electronics/forum/car-audio/133522.html |
