Is there a bigger Alternator?

[KAPTAINKIRK]

I have a 2006 F150TXR

Is there a bigger Alternator I can put on?

If there is one will this void my warranty putting a larger one on?

If none bigger is available can I just have mine modded to put out more,and of course I assume that will void the last two years I have left om my warranty?

Thanks for any and All input.....

Yamaha doesn't offer an higher output alternator and not aware of any others.
Not sure why you need larger alternator, may can use larger battery.

Already running two big batteries.
Stereo needs are why I am asking once in awhile when hitting some lows the stereo will start clipping.....of course only happens when the ladies are dancing,,,so they get upset.

So I am looking at ways to keep ahead of my amps needs at certain times.

I have the room so I am thinking of adding two more batteries.
