Hello,
T2500-1bd averages about 3000 watts x 1 @ 1 ohm. T215D4's handle 1000 watts each, so you'll be a little over powered.
Plan on an extra 300+ amps of current draw for the T2500-1bd. Ohio Generator makes a good alternator and Optima makes a good battery, get yellowtop.
Thanks,

If it draws more than 300 amps, then why is a 300 amp fuse recommended in the manual????
I would think it would draw somewhere in the range of....
3000 / 0.75 / 14.4 = 277.7Amps
And that's with a flawless electrical system and assuming the amp puts out 3000 watts rms with the stated efficiency of 75%. |

Just playin it safe devedo. In our lab we've had some T2500-1bd's do more than 3000 watts and pull up to 300 amps. As you pointed out, this most likely wouldn't happen in a car because we test with a constant sine wave signal and do have a solid, or flawless DC power supply.
As far as the fuse rating goes, a fuse is not designed to open at its rating, but over it. Most fuses can handle as much as twice their rating for minutes sometimes. Remember, the fuse is not there to protect the amp from doing too much power, but to protect the vehicles electrical system in case of some sort of massive failure, like your power wire going strait to ground.
Check out this page on fuses, alot of good info there. http://www.bcae1.com/fuses.htm
