[QUOTE="fixinit, post: 8732609, member: 670893"] Over planning is good if you'd like to keep your vehicle running for many years. Here's some math: 250 amps = 3450w at 13.8v (idle). Measure in your vehicle's electrical tax that's, let's say an older Toyota Highlander, with no accessories on--you're looking at an output of a 150A alt. Add efficiency loss to an aftermarket alternator build, and you essentially have 130 amperage reserved under ideal driving conditions. Of that 130A, you're throwing an affordable, but power hungry 3k amp into the mix cutting your alternator's efficiency by a 1/3rd. Now you have an effective 87 amp alternator post vehicle needs. 87A at 13.8v = 1200w. From there you can have a custom enclosure built to rattle your friend's ears because all of this wattage and money has essentially boiled down to merely impressing your friends and turning some heads. Just make sure that the HO alternator has a 1-3 year warranty OR you yourself can swap it out quickly if in an unfortunate chance it fails. If your ride is a daily driver and you're looking to rattle your friends' brains....skip the big 3 at first, install the cheapest max HO alt (keep your OEM in trunk with wrenches), buy a more electrical efficient lower wattage amp, test your battery, and most importantly--build or find a box that bleeds your friends' eyes when they sit in your passenger's seat while you kill a 50hz dubstep track. Sincerely, 1st post in many years [/QUOTE]
