Upgrading Electrical

[bs199sg]

Hey all, I just wanted to check with you guys on here if my to-be electrical setup will actually work and work well.

This is my current setup: HU: Pioneer DEH-X9600BHS; Doors: Kicker 6x8 40CS684 rms 75 peak 225 (x4); subs: Pioneer TS-W3003D4 rms 600 peak 2,000 (x2); sub amp: Hifonics Colussus Pro 5k 5,000 watts @ 2 ohms; door amp: Polk Audio PA660 600 watt; all running on 2 4 gauge wires to the amps and 1 battery. along with the stock alt, which is 65 amp at idle and 120 at peak (2,000 rpm).

I have a 2007 Ford Focus 2.0L

I'm looking to upgrade my alt to: https://www.dcpowerinc.com/fit/Ford~Focus~2007~2.3L-I4-Duratec/8407-370-xp.html#tab-product_overview

I found that the big 3 upgrade is a good one for increased power flow, so I'm looking at this: NVX XBG3PK 1/0 Gauge 100% OFC Big Three Kit - NVX

I am currently running 2 lines of 4 gauge wire to my amps from my main battery. This is the upgrade: InstallBay AK01 0 Gauge Complete Dual Amplifier Install Kit

My main battery is crap so i'm planning on getting two of these, one for the main and one for the trunk: Amazon.com: XS Power D3400 XS Series 12V 3,300 Amp AGM High Output Battery with M6 Terminal Bolt: Automotive

NOW, for the part that I'm sort of stuck. I know I need to install some inline fuses, but not sure of the fuse sizes. I did pick some out that I think will work though. The fuse for 2nd battery to my 5k amp: http://www.amazon.com/Blue-Sea-Systems-350-Fuse/dp/B000N9NTTW/ref=sr_1_1?s=sporting-goods&ie=UTF8&qid=1431791620&sr=1-1&keywords=Blue+Sea+Systems+350+Amp+ANL+Fuse

Fuse Holder: http://www.amazon.com/gp/product/B001VIVWAW/ref=pd_lpo_sbs_dp_ss_3?pf_rd_p=1944579842&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B000K2NZAU&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=0C9EPR2SHM62S564QQ00

This is the fuse between 2nd battery and pa660 (600 watt max) amp: http://www.amazon.com/Blue-Sea-Systems-ANL-Fuse/dp/B000THQSB4

Fuse holder: Amazon.com: Blue Sea Systems ANL Fuse Block with Insulating Cover - 35 - 300A: Sports & Outdoors

I'm not sure if I need a fuse between the batteries. I don't think so, but I figure I'd ask just in case.

I'm also not sure if I need a relay between the batteries. I won't be running the car in acc mode. Only on or off. So I don't see a point in getting a relay.

If there's anything wrong in my electrical logic plz reply.

Thanks for reading this long post. I greatly appreciate it!

That alt is a beast. Won't have any issues with a 370

People have said that amp actually clamps about 2.5k, so your electrical will be more than fine

Don't get rid of your 4 gauge. Just add the Zero gaige if possible. The more runs of anything the better.

I do not fse between the batteries in my battery bank, but you should fuse between the front and back ones.

XS power is awesome, but you can get AGM batteries cheaper from local battery shops.
