Question

How many amps are needed with a 2ooo watt sub?

Answer 1

power gain

+db gain=10*log(p2/p1)

+db gain=10*log(2000/600)

5.228 db

------

v=i*r

p=i^2*r

----------

89=i*4

2000/4=500

---------------

89 volts RMS @ 23.36 amps into 4 ohms for 2000 watts

Answer 2

just one amp that is 2000 watts

you can use 2 1000s, but you are going to spend more

it also depends on the brand of the sub if they are a good brand i am guessing it has an rms of about 800-1000 so make sure you buy a good amp, not a cheap one that has about 900 watts rms at 4 ohms

Answer 3

approx  2000*1.414/12 Peak

Answer 4

info needed to match an amp to subs

the subs RMS wattage (not peak/max, they mean nothing)

the subs setup (DVC or SVC, voice coils)

the subs impedance (ohms)

you need to match RMS wattage's at the correct impedance (ohms)
