Still dont know if im swapping out my 4.100 to a different amp or just replacing it and hoping for the best. I am also going to be running my 1.600 to a sub. Would my 4ga power which i have already ran be sufficient for these 2 very efficient class d amps? Its a run from the battery to the back part of the trunk. Thanks guys!

 

i would use something thicker on my old car i was running 2300 watts and i used a 0/1 guage for u id prob go with something along 1 or 2 guage 4 is a little thin IMO

 

Dunno what amp you're talking about but I'm guessing an Alpine PDX. The 1.600 is a 600w amp so 4 gauge will be fine. Easiest way to tell is by the power inputs on the amp. They'll only accept up to a certain size. Manufacturers know what size wiring is needed so if it's got an opening for a 4 awg, a 1/0 is not necessary.

 

For 1100w RMS, I'd go with something thicker, since you'll end up with about 12 foot of wire, and at that distance, 4 gauge is only good for about 800w.

Dang. When i looked at 12v i read that those calculations were with amps that have approx 50% efficiency while my pdx's are supposed to have 80>. Now i gotta rewire power but meh. I hope knu koncepts has some in stock now. Thanks guys!

 

wire is about current not watts

I think 4 ga will be ok

im running 1500 rms on 4 ga from the battery to the trunk and its fine

 

1/0

 

Yeah im just gunna buy 20ft of 1/0 of knukoncepts and a new distribution block. My lights are dimming so im prolly gunna get a grounding kit and new high out alternator.

 

Run 0 from batt to distro, and 4 to each amp

Big battery would help too..no need for an alt

 

Well I never play the stereo with the car off so a new battery isnt needed as much other things.

 

That's not the reason for a bigger battery. How do you think your amplifier gets it's power? If it's not supplying enough, other areas of the car will hinder, example: your headlights dimming.

 

Been looking at the Kinetik Batteries. Would the hc1800 be ok? Says it is for 1800w but i think thats with everything else in the car. I am running a 600w rms mono amp and going to be running a 480w rms 4ch amp. This new battery has 3 times the amount of cranking amps that my current interstate megatron battery does. Thanks

 

Check out Sears DieHard Platinums... will be cheaper than the kinetik and perform just as good

 

According to sears website they are around $200 which is the same as the kinetik I listed. The sears diehard says it has around 800 cold cranking amps. Not sure what the kinetik has cold but says 1900 in general amps.
