200 amp Alternator
The first day I had it, Damn it was so so sweet. I let my car run for 5 hours at a party, and then when I cut the car off, it was over. My brand new(2 days old) Optima battery had been drained dead cause my alternator was only supplying 115 amps, and at 1/3 volume I was sucking over 100 amps. So when I had it all the way, I lost all power when I tried to start it up. The battery got so drained that even after an 8hr slow charge at the shop couldnt save it. I just got a 200amp alternator now, and it is way louder that it ever was. Both side mirrors lost all electronic control, and my license plate lights are blown. Yeah it is loud as fuck and with the MYX 6 1/2" up front it sounds nice. Anyway after all said and dont it came to roughly $4800 but it was worth every dime
Which Optima? If it was the red top, I'm not surpised. That is a starting battery, and doesn't like to go below 11.5 volts very often, or for very long. If its your only battery, go with a yellow top. If its just a stero battery, go blue top.
In my Escalade, I have a voltage sensing system that links my two batteries. As long as voltage stays above 11.5, both my main (yellow top) and my rear battery (Stinger) are connected. Once the voltage falls below 11.5, they are seperated. Since the audio / video all runs off the back battery, this take the load off of the starting battery. I can run the rear battery completly down, and still start the car.
So, I can sit at the stadium and watch the pregame on my 27 inch retractable TV,without worrying.
The device also has an LED that goes from green to yellow to red, so you know what state its in.
