Upgrade alternator and/or battery?

Upgrade alternator and/or battery?
I have a Kenwood DDX-419 stereo with all 4 door Alpine SPS-610 speakers, and I want to get some subs.
The Alpine SWS-12D4 subs really caught my eye, I want 2 of them (they are 500w RMS each) and I bought the Kenwood KAC-9105d amp to go with them (900w RMS at 2ohms).
My question was will I need to upgrade my alternor and/or the battery? As far I know I have the stock alternator and a NAPA 75 battery. I will not be installing them myself, I don't know how ha. I'm taking it to my local shop who offers lifetime warranty.
I have a '99 Blazer LT 4dr btw
Thanks for the help/tips!

for a stereo alot of ppl run factory battery and alternator and only upgrade if ur doing alot of audio competitions or if ur running alot of offroad lights and power equipment. just do the big 3 upgrade to ur vehicle and it should help with the electrical system to ur vehicle. if u choose to upgrade the battery i recommend the optima yellow top battery for audio equipment

0g is useless unless you are running some serious serious power. 4awg will be more than enough.
I am running 4awg from alt to battery, grounds, and all the way back to the amp, and I am pushing about 800w to 1 12"... not a single problem. even when AC or heat is on high, headlights are on too.
also, the factory alt will be find as well. most of the time I never drop below 14v

No. You need a longer belt because using the larger alternator moves the pully out a little and you need the longer belt to fit.
