How Many Watts Do I Need To Power My Subwoofers

Posted in Car Electronics

I’m getting 2-12″ Boxed Kicker Comp Subwoofers that have 600 watts peak power, does this mean i only need a 1200 watt amp to power them both?

    1. B-man says:

      Get a mono amp (class d ) that pushes 600 watts RMS into the final ohms rating that the box comes out to. ( I’m almost positive it’s either 2 or 4 ohms.)

      Ideally you should only need a duel channel amp, 1000w alpine or fosgate, bridged connection for 2ohms, and dont skimp on the higher rms amps. but you shouldnt need to exceed 1000w unless you wanna replace your speakers often. but bare minimum you can power your speakers with 300w amp for the two.

      Kicker speakers are very senistive speakers therefor you need to match the RMS as close as possible 2 kicker comps run at 600 watts RMS therefor you need a amp that’s right around 600 watts RMS. If you bought the box and speakers together as a KICKER package then you can look on the connection teminal cup on the box to see if the box is at 2 of 4 ohms. If it is at 2 Ohms then your gonna need a amp that is stable at 2 Ohms Ex. the Kicker 05ZX750.1 would work fine even though the the RMS is 150 watts over. DON”T TURN THE GAIN ALL THE WAY OR YOU”LL FRI THE SPEAKER

      Please listen if your speakers are 600w peak then a 1200w amp will blow them because you will max them out!Your rms is the power indicator and how to properly get the most bass and efficient numbers from your subs.The rms on a 600w pk sh be 300-400w so you should get a mono block class D at least 500rms or a 2ch amp at least 400×2 remember you can get a amp with more reserve power but be careful not to burn your coils pushing them so good luck…….. ^(

      Add the RMS watts of each sub and find an amp that matches this at the required impedance and your golden.

      To bucketo(crap),

      I started reading electronics books when I was seven, I designed and built my own circuit boards when I was eight. I started acquiring all sorts of equipment to help me in my “hobby”. I got my first oscilliscope when I was ten, it was a Zenith Heath-kit.

      At age ten is what I’m basing my “25 years experience” on since it was then I had a full understanding of electronics and I was already making advanced designs. I made my first tape-recorder at 12 years old.

      Unfortunealty, had I known about patents at 16 I could have been the the remote start king as my 1963 VW Beetle was probably the first car to have it (1986).

      I then went to college, got my degree, went to Mississippi for my Peavey training (met Mr. Peavey) and I am now working for a commercial audio company here in Illinois that installs sound system in churches, schools and other venues that require complex systems.

      So with all of this, I suggest you take your weak, little mind and go pester someone else.
