    got a strange voltage problem. i think

    we have not started the install yet so there is just factory replacement speakers in my Tahoe now (focal's) I have a optima red top in the stock location and did the big 3 upgrade, and everything was fine. I just installed a new xs power D3400 under the hood in the 2nd location. 1/0 gauge wire rand to the alt. and grounded to the alt bracket, now when I start the truck the voltage reads high 14's,(volts) after a few miles down the road it has dropped to mid to high 12's (volts) and this is with just a kenwood head unit and 2 set of focal components, NO AMP at all. any idea whats going on

    Your vehicle's ECU is regulating your voltage.

    Ride around with your fog lights on.

    Try disconnecting the 3400 and see if the voltage drop goes away. Was the 3400 fully charged?

    I don't have fog lights (its a LT lol) I may disconnect it tomorrow when I get back to work and see what happens

    the 3400 was holding at around 11 volts out of the box from crutchfield

    Your 3400 needs charging. If it doesn't help, you got a bad battery.

    Re: got a strange voltage problem. i think

    what do I need to keep and eye on. from what I can tell from the sheet that came with the battery is not to charge it at more the 2.4 volts per cell, which is 14.4 volts right??? so don't most all battery chargers charge to 14.4 or do they put out more than that ?

    ok I was able to find a smart charger here in town, when I went to leave the house, I disconnected the d3400 and checked the voltage and it was 12.3. this is throwing me for a loop

    yea sounds like it may be bad. How long was it on charge? and are you going to get the smart charger if you already havnt?

    when I said I disconnected it, I meant I disconnected it from the alternator so it would not be hooked up anymore. then I check the voltage and it was in the mid 12's. I haven't put it on charge yet, I was going to do it tomorrow at work

    oh ok. even tho it was on the alt it still probly needs some charging. just put them on like a 2amp charge on a smart charger and leave it on there for a while, may take a few hrs
