Suggestions on proper electrical upgrades to power this behemoth?? (3500 soundqubed)

[2dee11]

Hey Guys! You all helped me out a ton with my old grand prix and getting the audio all set up on it and i could use some more advanced help this time! i appreciate all the input in advance!

2008 GXP

my equipment on the way is

2 soundqubed hds315 1200 watts rms a piece link here
powered by a soundqubed q1-3500 watt amplifier link here
(and eventually adding their q4-90 amp to power the interior speakers link here)

obviously i will need to use 0 gauge wire for everything
will definitely be doing the BIG 3
i will need at least one new battery under the hood (possibly one in the trunk too?)
and im guessing a new alternator as well

my question to you guys is how big of an alternator would i need and do you have any suggestions as to which ones? as well as what batteries you guys suggest and if one under the hood would be enough or if i should also add a second one in the trunk!

im always a fan of going cheap but good quality definitely dont want crap i just want to be able to sleep at night knowing all the electrical is nice and sound and not have to worry about having any problems. any input or advice would be awesome! im just not very good with figuring out the total amps and load on the system it would have

should be able to get up to 180 amp alternator stator. i rebuilt mine with stock case in my 96 gtp.

At this point I'm waiting on a reply from iraggi for a quote on their 280 or 320A And also gunna go with a d3400 xs power battery to replace the stock battery and potentially add a second one too

AGM up front. At least one Group 31 battery in the rear, a minimum of two runs of quality 0 gauge to the rear...and 175-200 amp alt. That amp is power hungry and you're going to be severely under powering if you don't do the mods to support it.
