Wiring 2 amps

[cbuts 10+ year member]

i currently have 4 guage ran through my car.

the guy at future shop says that my panels may not fit fine if i run a whole 0 guage kit with having the 4 guage ran already.

would it be best to run them both from the battery or run 0 guage split into 0 and 4 guage?

ill be running 2 sa 12s, and a rockford fosgate 1500. and ill be buying another amp for my speakers, he says 4 guage will be fine enough for the sub amp, but do u think i should use 0 anyways?

can my amp hold 0 guage?

whats the best way to wire this?!

I have used a 4 ga run for two power hungry amp, such as the Audiobahn HCT 4125, and the 18001dt.I had no issues with 4 ga run, to a distrabution fused block to split my supply needed, I even ran a small battery for extra power surges .4 ga is fine with a dist block..Try to do the big three as well will be fine.Ther should be a thread on here for it.I think 4ga will be just fine,and save you some money ,as wiring has become quite expensive..In my opinion

refer to the amplifier owner's manual for wire size and fusing requirements. you can download it if you lost it. you didn't give us enough of a model number to determine and you should read an owner's manual before installing anyway.

as long as the 4 awg is properly fused at the battery for 125-150A, you can certainly try it. as you approach 100A of draw you will get noticable voltage drop along the 4 awg which means less power out of the amp. at that time you can upgrade to 1/0. but you don't run 1/0 under the plastic door sill panels - you route that wire along the floor. so yes, 1/0 will fit fine if properly routed.

You've already spent a good chunk of change on your subs and amp if you're going with sundown and Rockford... You should just go 0 gauge, it'll leave room for upgrades and allow enough flow. I guess in my opinion, why not just get the 0

4g OFC from knu is like $1.50 a foot and the 1/0 KCA is $2 a foot lol. the KCA handles an extra 100a too
