Yeah, I'm going to run a bigger alternator cable, and upgrade the battery to a Stinger or Odyssey. Hopefully the stock 130 amp alternator can handle the load for a while. I'll probably run 1/0 to a dist/fuse block in the rear and then 2 guage to each amp. I'll have to run the cable down the passenger side because i have already ran some wire down the driver side for other accessories. I might even have to run the cable underneath the cab and then come up into the back of the cab. 1/0 is pretty big.
That SX 1250.1 is 1 ohm stable and the 900.4 is 2 ohm stable. But I probably will run the 4 channel amp at 4 ohms per channel, and the sub amp at 2 or 4 ohms mono, so the amps won't pull as much current.
That 1250.1 requires a 150 amp fuse.

And I will probably put a 100 amp fuse on the 900.4.
Oh, and they aren't refurbished or B stock amps. Retail receipts. I wasn't really shopping for amps near this big, but what a deal, huh?
I think that the wife was selling her husbands audio equipment real fast while in the middle of a divorce. She doesn't seem to know what the amps are really worth. Her husband (Ex-husband) will be pissed!
