    upgrading Power and adding a extra battery help

    Alpine Multimedia Station - Alpine IVA-D310R+NVE-N099P
    Alpine RUE–4141 remote

    2 x Alpine 1241D 12” type R subs 1500W each
    2 x Alpine swr1242d 12” type R subs 1500W each

    components set Alpine SPR-17S 17cm
    ALPINE SPR-17C Type - R, 2 Way, Co axial

    2x alpine MRD-m1005 V12 amplifiers
    ALPINE V12 MRV-F345 4-Channel Car Amplifier


    20” roof mounted screen
    Power cap 1.2 farad

    4 AWG Wiring


    i have currently just put this setup into the car, im obviously needing more power to run it efficiantly and to stop the battery from constantly going dead.

    what do you advise? i was thinkin:

    70ah 93189922 diesel battery up front for the car
    Odyssey PC1700T high performance battery in the back for the ice

    Then running 0Awg From the Alternator to chassis 0Awg from both battery's negative to chassis and 0awg from engine to chassis

    checking the alternator to see what it currently is if its low then upgrade it to 120amp alternator or any recomendations?

    then there is the factor on how to connect both the batteries up, been doing some research but its starting to get mind boggling, im assuming im just gonna wire them up with a 0awg cable with a fuse within 12" of the posative terminal of each battery, then either leave it as it is, put a relay in place or an isolator which is where im confused

    You need a split charge relay so that both batteries are only connected while the engines running

    is this what i need?

    assuming i would connect the posative of each battery to the nuts and then one of the spade connector is a earth and the other spade connector goes to the alternator?

    thanks for you help.

    Correct on every count

    I have connected it to the fuel pump instead of alternator on some cars though to make life easier

    just to clear this up fully, what size cable should i use to connect it to the earth and to the alternator/fuel pump? and does it need to be fused?

    im gonna use 1/0awg cable for the big 3 then also 1/0awg for the alternator to battery fused with it close to the battery (size of fuse?)

    then 1/0awg from front battery also fused close to the battery (what size?)
    to the split charge relay, then 1/0awg coming out the relay to the rear battery also fused close to the battery (what size?)

    then 1/0awg earth for rear battery, then 4awg for all components to connect to battery

    The relay contacts will take very little current to energise so you just need thin 1mm cabling (we use stuff that takes 14amps). Adding a small fuse would be a good idea

    you've been of great help, thank you. where is the best place to locate the relay? in the engine bay or behind the dash just after the firewall?

    im assuming once that is installed the relay will just do its own thing and work how it should, charging both batteries and allowing them to run together when the engine is running, but splitting them to seprate circuits when engine is off

    when you say small fuse would 10amp? be suffice.

    also for the 3 anl fuse holders what amp fuse would you think id need?

    one from the alt to front batter
    one coming from front battery to relay
    one coming from rear battery to relay

    and finally would you recomend connecting the posative amp cables etc directly to the battery clamp or use a fused distribution block?

    and would you recomend an earth distribution block, or connect them to the negative clamp on the battery,

    i think all of them would probably work about the same really but just want to double check and be 100% sure

    When I say small fuse I mean 3 amps max would be fine

    The alternators not fused at the moment so you don't have to put one there unless your worried about the wire. If you do put one there one needs to go by the alternator and one by the battery.

    Can't really recomend fuses etc as it's not really the area I deal with but bare in mind that if the rear batterys flat and the engines running all the drain will be on the front battery so a fuse to match the rear amps together would be needed.

    I'd just go for a single terminal rather than fused distrubution block at the battery
