[QUOTE="Roland, post: 8201965, member: 647142"] What He says X2. I'd say measure instead of guessing. Monitor your voltage. Look for excessive drops and IF you have them, correct THAT problem. You can also get an idea of what your system actually draws by under fuseing your amps (inline fuse). Drive your system as hard as would with your most demanding music, and see how low of fuse size you can use before the fuse blows. I have ture 3000 watts RMS of amps in my van and my inline fuse is 80 amps. (I could get a 60 amp fuse to blow but have never blown the 80) So my 130 amp Alt is good enough leaving 50 amps to run my normal car stuff. My voltage when running is 14.4 with stereo off. With the stereo running loud it drops to 14.2 this is acceptable drop even a bit lower would be Ok. Just no the lower your system voltage, the shorter life your battery will have and i would not have a system below 13.5 running volts, but that's me. IMO we put to much credit on BIG 3. While it will never hurts to do that, and it can help a lot of people, it is not ALWAYS necessary, and SOMETIMES it is just a very minimal benefit. I run a 4 gauge wire and no big 3, i just made sure the connection i do have are as good and clean as possible. Just My Opinion [/QUOTE]
