Another stereo/power question

[fxnjetz]

Greetings all,

Earlier, I posted a question regarding power wiring for new stereo system, and got great feedback. I've now got a better handle on the system I want to run, but am not sure If I'm asking too much of the electrical system. So.... 2 - Alpine pdx-5, 5 channel amps that are rated at 75 X 4 + 300watts mono. One of these will drive 2- 6.5's in the berth, and 2- 6.5's in the salon, also, I plan to drive 1- 5.25" subs in each of these two compartments. The second of these power the 4-6.5's outside along with 2-10" subs. The amps are fused for 80 amps. I dont expect to ever run this rig at full tilt, but I cannot seem to find anyone who can give me a reasonable continuous amp draw rating. My power scheme is to run 1/0 gage for power and grd from the house batteries protected by a 100-125 amp fuse, then to a fused distribution block, then 4 ga to the amps.
Any/All thoughts welcomed.

It won't be too much for the electrical system, but, the batteries might not last too long. I would put an extra one in the bank that's doing all of the work. I'm not too sure of the charger implications in doing this though.

As long as you are not one of those guys who anchors all day and lets the world know how loud your stereo goes, your batteries will be fine. Those digital Alpines are great in that regard. They also run relatively cool. If I didn't reuse most of my amps, that is what I would have gone with.

You can get a beefier fuse block. I think I have a 300 amp fuse at the battery.
