3 Kicker Subs but what AMP?

Question

Im going for 3 Kicker 15 L7's the 2000watt 4ohm subs...

I'm wondering what kind of sub i should shoot for going.. i was lookin at a hifonics 2/1/mono 3200watt amp... the colosssus XX and then i was thinkin about gettin a big monoblock from kicker...

im not trying to spend a grand on an amp but im definately willing to almost spend that much :-p someone let me know! :D


my goal is to shake your car if your 2 cars behind me

i am not sure i can follow... id need to buy a stronger alternator for my car?

Answer 1

The amp you choose must be 1 ohm stable since those subs wire in parallel will be 1.34 ohms. You can go with the colossus or thor of the XX series.

You'll need an alternator upgrade....

Something to consider...this is an example...

To calculate the current draw of an amplifier, multiply the number of channels by the RMS watts per channel (a 2 channel amp rated at 500 watts RMS per channel would be 1000 watts). Double it to account for amplifier inefficiency (1000 watts X 2 = 2000 watts), then divide by the average output voltage of an alternator, 13.8 volts (2000 divided by 13.8 = 145 amps). Since the average music signal requires about 1/3rd of the average power in a test tone, divide by 3 (145 amps divided by 3 = 48 amps).

This is an average approximation of current draw and it can go higher. So I would gather between *48 and 72 amperes for this example.

The alternator of a:

compact car is about 35 amps
mid-sized car is about 65-75 amps
SUV is about 145 amps

Calculate 40% of the amperes of the alternator you have now. This is the average current the car uses when running. Add this number to the approximate average current draw (*48) of the amps you calculate, and you will come up with the mimimum average current required to power the audio system and vehicle.

Answer 2

Why 3? you could likely get equivalent to or better than with a million or 2 better wattage subwoofers and amp. human beings get all of those subs because the subs with information from them self do not push as demanding, so u favor better for a louder sound. Why kickers subs. they are way better high quality subs that value 1/2 the cost. attempt Phoenix Gold, MA audio, memphis, better end JL's, MTX.
