Question

If you have a sub with 600 rms and 4 ohms and 2000 watts how many amps will you need?

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

Definitely go with 1 life, i underpower my two 12" subs by about 50-100 watts and they still hit great AND it puts my mind at ease to know it'll take alot more to blow them while i have them turned all the way up (which i do often)!

Answer 3

u would only need one amp probally 650-700 rms because u always want to over power ur sub not under power

Answer 4

you should only need one amp there are some out there with 600 rms @ 4ohms but they're kind of hard o find...you cal also use a 500rms amp @ 4 ohms those are easier to find and will still power your sub pretty well....ask around there might be other options

Answer 5

This question isn't understandable.  I'm assuming just one.....
