Can I run two amps off of 4 gauge?

[01rednavigator]

I am currently running the following in my 2001 navigator.

4 Pioneer TS-D6802R 6x8 speakers in the doors. Peak: 520 watts per pair / 260 watts each

RMS: 120 watts per pair / 60 watts each

I am powering them with a Rockford Fosgate Power T400-4 4-Channel Amplifier.

4 ohms: 60 watts x 4 chan.

2 ohms: 100 watts x 4 chan.

Bridged, 4 ohms: 200 watts x 2 chan.

So am running 240 watts of power with my current speakers.

I used a good quality 4 gauge amp kit to install the amp (NVX)

I want to add a sub and amp to my system, the following is what I have decided on.

Rockford Fosgate R500X1D

500W RMS Monoblock Single Channel Class D Prime Series Amplifier

RMS Power Rating:

4 ohms: 300 watts x 1 chan.

2 ohms: 500 watts x 1 chan.

JL Audio CP112-W0v3 Single 12" 12W0v3-4 Loaded Ported Enclosure.

•Power Handling: ◦Peak: 600 watts

◦RMS: 300 watts

So I would be running 300 watts with this sub and amp, I would be running 540 watts total with my speaker amp and with this sub amp.

I was going to get more 4 gauge wire and power and ground blocks to run off my current 4 gauge wire.

Will 4 gauge be ok to run with this setup? or do I need to run 1/0 power and ground to the power block/ground block and 4 gauge to amps?

With my current 4 gauge power wire I had to run approx. 18-20 feet of power wire to the amp, I had to use this much cause my Navigator is so long.

So will I be good with 4 gauge with this setup?

Most 4 gauge can hold up to 150 amps of current as long as those amps dont exceed that with both there fuse ratings added together you are more than fine

I've safely had more current draw than that off of OFC 4 awg wire. You'll be fine.

Thanks for the help, am I ok with the 18-20 length of power cable? or is that to long for 4 gauge?

It's not too long.

Thanks for the help, is that sub and amp a good combo?

I wanna run 2 of these prime 500x1 amps in my s10 on 4 gauge wire split with 4 gauge again is that ok gonna have each 1 with its own 12" l3 will this be ok gonna use the knu koncepts kolossus power wire for this if so birth sheets say 642rms. Also are there fuses inside these amps cause there's none on the outside? Surly there not unused are they sry for the stupid questions
