2awg

15L72?  So dual 2-ohm na S15L7 yang sub mo?

I think a typical birthsheet of a KX1200.1 goes over 1,500 watts.  Even assuming that you just get 1,200 watts from that amp and your power wire will run 15 feet from the battery in the hood to the amp back in the trunk, using 4awg power wires will still be a little inadequate.  Considering that you might run longer wires than 15 feet and the wattage might surpass 1,200 watts, 4awg will be totally insufficient.

With your +kWatt power amp, you should invest in 2awg wires to feed them.
Who puts the MOO in smooth?!

for the power cables, would it be okay for the cables to be thicker by at least 2 gauges, like say you need a gauge 4 cable, can you use gauge instead to be on the safe just in case you are not sure of the power requirement of the amps?...thanks

as think as your budget would allow...

Using thicker wires that necessary isn't a bad thing.  This would give you the option to upgrade to amplifiers of higher wattage in the future without having to worry whether your power cables would be up to the task or not.  However, you won't pose any advantages in terms of performance if the current draw isn't too high in the first place.

thanks for the reply!..will definitely use thicker gauges para we can do some upgrading in the future.

I was going to give the formula to get the right wire gauge, but then I found something a whole lot easier to unders, Below is the Car Audio Cable Recommendation chart from the IASCA Handbook. :)

Length of run (in feet)
Current     0-4  4-7 7-10  10-13  13-16  16-19  19-22  22-28

   0-20A     14   12   12     10     10      8      8      8
  20-35A     12   10    8      8      6      6      6      4
  35-50A     10    8    8      6      6      4      4      4
  50-65A      8    8    6      4      4      4      4      2
  65-85A      6    6    4      4      2      2      2      0
 85-105A      6    6    4      2      2      2      2      0
105-125A      4    4    4      2      2      0      0      0
125-150A      2    2    2      2      0      0      0     00

(Sorry I could'nt get it to align properly.)

Anyway, the formula to get the current is

AMPS (Current) = Watts (Power) / Voltage

e.g.

Given:

Power = 1,200 watts
Voltage = 12 volts

Unknown:
Current

Formula:
Current = Power / Voltage

Solution:

Current = 1,200 Watts / 12 Volts

Current = 100 amperes

Lets say we estimate a cable run of 20 feet from the car's battery to the trunk. Based on the chart above, we should be using a gauge 2 power cable. :)

tach, nice post. u jst taken me back to school  ;D biro lang bro.

btw, like they said, tama lang yan g2 na wire. mahirap kasi pag nagtitipid ka eh, whole system mo will suffer.

would it be a wise move to get another battery and place it in my trunk??? para short nalang yung power cable ko...iwas static pa :) ok ba yun???


OT: ang hirap humanap ng grill ng 15L7s..baka may alam kayo, kahit 2nd hand..kahit anong kulay! kahit pink!

kung kaya ng alternator mo extra load why not.  ;)

pero baka overkill ... try discussing your setup first with other people na knowledgeable sa car audio maybe there a economical yet effective way of doing it. IMHO

IASCA rules state that you have to circulate fresh air from the outside to vent the battery's fumes.

i think 4 gauge is enough, but 2 gauge is far more best!

it's like watering plants with softdrink straw with ur 4

gauge, well, somewhat like that. get the picture?

depends on ur whole system and vehicle.

BOOM! 8)



san nakakabili po ng 2gauge?? kelangan ko ba nito for driving 15L72 powered by kx 1200.1??? or pwede na yung 4guage?

4awg for the KX1200.1
« Reply #12 on: November 27, 2003, 08:58:16 PM »
No, 4awg is not nearly enough.  In fact, Kicker recommends using 1/0awg for the KX1200.1.
