I have a few battery questions.

    Reason why I’m asking. Trying to learn here on the capabilities of these vehicles for what I have in mind for.

    That would be a "No"!

    RMS is the power rating with distortion meeting standards, peak is how much power the coils can handle.

    What does the vehicle have to do with it, this is separate from the vehicle. Right?

    Trying to figure out if the inverters, can handle the QSC speakers and if the alternator can charge faster then the speakers can drain the batteries. Reason why I was looking at possibly installing a second battery bank to slow the draining of the batteries and increasing the alternator output.

    As @mhyn stated the inverters will cause interference.

    The speakers will only be on when the vehicle is being driven and only when I want to hear it. 95% of the time it’s on it will be at 5% volume. That 5% of usage when Not sure I can even stand it being at 100% of volume. As I can’t even stand next them in my back yard when it’s at 50% volume.

    The entertainment system is one issue. There are other things I want to run off the inverters, these aren’t the kettle and fridge type of device, these are things I want to design for the truck and or modify current on market systems to work with the inverters.

    So I’m trying to figure out if it’s possible to do all of this without the use of a generator. Just an alternator and extra bank of batteries.

    My goal is to maybe start a new line of products for the new age show truck owners.

    Ok ...


    "Trying to figure out if the inverters, can handle the QSC speakers and if the alternator can charge faster then the speakers can drain the batteries.

    No, no matter what others say it is NO.

    The batteries can NOT recover fast enough to cover the constant current consumption.

    No size alternator would "recharge" the bank in a quick time to even 75% when the current consumption brings the bank down to say 30%.

    Why people put in ultra caps in their audio systems is because it has a fast acting recovery compared to batteries.

    Why not a generator?

    I just don't get it, the generator will produce better power and can be filtered easier to power high wattage systems.

    Oh and you do know that you can't just use the standard 000 type cabling, you have to carefully plan the cabling and I doubt an "electrical engineer" without practice knowledge wouldn't know what is needed and how to wire it so not to explode a battery or two,

    I guess the main question I have to better understand this is this.

    If the QSC pulls 2.1 amps at 120v from the inverter what does the inverted pull from the batteries to provide that power to the speakers?

    Ten times that plus some extra for efficiency losses. Just under 25 amps on the 12V side
