I need to know the max load that an amp will put on a battery when turned up and all speakers loaded!
I know there are some very smart people here who might know how to figure this out, so give it your best!
PS: This is the amp http://www.kicker.com/06/tech-support/manuals/manuals/IX406manual.pdf
Thanks
Assuming you will power 6 channels @ 40W RMS,
Total power is 6 x 40W RMS = 240W RMS
Change to peak power: 240W x sqrt(2) = 340W peak
Assuming 100% efficiency of the amp (all power dissipated in speakers), total power input to amp is 340W peak
Watts = Volts x Amps
rearrange:
Amps = Watts/Volts = 340W/14V = 24 Amps peak
Thanks!! I had just finished a Google search on that exact question and came up with the same info. I did forget about the peak part though!
Thanks
Jeff,
I asked my buddy who manages & does the install at a car stereo shop here in Modesto.
Here's what he said:
The Maximum amount of Current that the Amp can draw from the Battery is EQUAL to the amount/Size of the Fuse in the Amp.
NO amp should be able to draw more current than the Fuse in the Amp.
20 amp fuse X 12v = 240 watts
30 amp fuse X 12v = 360 watts
The 5 channel US amps amplifier I have in my dually uses 3 30 amp fuses.
It's plenty.
