[QUOTE="ThxOne, post: 8832584, member: 675210"] My car has a stock 90a alternator and I know that the manufacturer determined this to be adequate for this cars needs with ALL electrical loads being used i.e. A/C, Lights etc. I have added the load of the aftermarket car stereo into this mix. I can listen to my radio without any real issues but I know I am leaving some amplifier power on the table. I say this because the same subwoofer amp and subs I am using now which are in a trunk of similar size and using the same enclosure do not hit as hard or loud as they did in my G6's which had all the same electrical upgrades (Big 3/4 extra ground) all same size cables as well. The differences are the G6's had normal lead acid batteries but had a 125a stock alternator. This car is 90a and I upgraded to an AGM. So I guess what I am getting at is how down on power are my amplifiers? All RF Punch with the sub amp being the Prime. 400x4 - 500x2 - 1200x1. These are the amps. I will be swapping out the sub amp for my Smart3. I know the rule, it takes power to make power and I don't even want to attempt the smart3 yet until I get the new alternator. This brings me to another question. With the new alternator will it be enough to allow the amps to make full RMS power? Will it be safe to substitute the Smart3? The new alternator will be 200a @ 1200rpm and 100a @ idle. I am not above adding a second identical AGM in the trunk. Will an additional 110a do the job? [/QUOTE]
