[QUOTE="brassknucklez, post: 1757424, member: 567682"] I have an iraggi alt. I had it tested under a load. It is doing 180-190 amps. Voltage is holding 14.2 at a 100amp load. My big 3 is all done using 1/0guage welding cable. Battery right now is the stock battery that came with the car. I do have a new yellow top ready to install. What worries me is my potential power cunsumption. The sub amp is a Soundstream PCA3500d which does 3500watts at 12volts, and closer to 3900at 14.4volts. The component amp is a DLS Ultimate A4 which will be running bridged at 4ohms.. That is 500watts. So this system has the potential of 4000 watts. I am guessing my A/C and basic car stuff will be around 40amps. So, being conservative I've got 140amps left. 140*14.2=1988watts. I'm super concerned. How much will these amps actually use at daily listening levels? I do tend to listen to music pretty loud, and favor lots of bass. I believe dom iraggi charged me about 400 for the alt. I had to spend another 150 to have it put in. I don't really want to spend 600 or whatever he charges for a 300amp alt, but I don't want the entire system to suffer because I don't have enough current to power the equipement I have. HELP PLEASE !! [/QUOTE]
