    Adding 2nd Battery Questions

    I have a 1000 Watt Mono Alpine and I am looking to upgrade my 4 chan Amp to a better one that puts out more.

    My 4 Channel Amp is 50 RMS each channel, but my speakers can take more(75 Front, 90 Rear) I dunno if I can get an amp that has different outputs for the front and rear channel? Any suggestions on an amp?

    No sure on my alternator output its not very high, its just a stock replacement, it is for a Suburban though, so I would guess it puts out 60-85 Amp max.
    So I am going to add a 2nd battery in the rear, don't want it to be connected with the front battery, and I also would like to use a smaller wire from the Alt to the rear bat so my stereo doesn't 'use up' all my alternators output making my car components run off the front battery, is this a good idea or will the rear battery not charge very fast with a smaller wire?

    I was thinking with either going like this

    Both amps running off the rear battery, not draining anything from my front.

    or like this http://i233.photobucket.com/albums/e...g?t=1256496863

    Amp II being my 4 chan. it runs off the front battery/alternator(Better if I limit the power going from the alternator to the rear battery by using a smaller wire) then the subs can pound away from their own battery.

    I would like to know what size fuses I should use and if the amount of fuses I included would suffice?

    Also would like a suggestion for the rear battery, I am looking to by a kenetic.

    I'm afraid I can't answer your real question(s). But I would suggest in both setups, that you plan on hooking up that rear batt neg to ground, or even a straight run to the front batt, I'm pretty sure it won't do any good if that's not connected to something, but I could be totally wrong, I don't know much about setting up multiple batteries.

    Ya thats just an error in my diagram, the battery would be useless without a ground...
