Do you add up (RMS) watts in a subwoofer system for finding the right amplifier?

Question

Cuz,
I have
a quantity of 3
Kicker CompVR12 DVC (4ohm per Coil)
RMS 400W per sub

Wired series across individual subs then parralled over the hole thing to make 2.67 Ohms.

DO you add up wattage (400W) +(400W)+(400W) in order to find the right amp? ( so would an amp that is 1200W x 1 @ 2.67 Ohm be the "perfect" amp) Or do you find that a different way

Answer 1

yes 1200W at 2 ohms would be great for what you are doing. and it would be better to run ONE 1200 watt amp instead of three 400 watt amps. for one 3 amps at 400 watts will be waaay more than 1 amp at 1200. second its much easier to wire one amp than three,and cheaper since you wil be buying less wire, and taking up less space. and peak power you should never pay attention to, despite what the other guy says, an amp hardly ever, if it ever reaches peak power. what he described was clipping, which happens on any amp regardless of the wattage if the gains on the amp are set too high.

Answer 2

Alpine MRP-M2000 Mono Power Class D Amplifier - 1,500 watts RMS x 1 at 4 ohms (2,000 watts RMS x 1 at 2 ohms) That amp is very powerful. Make sure your car battery is good! The reviews on Amazon also proves this amp is a beast!

Answer 3

find an amp that can put out around 1500 watts RMS @ 2 ohms as i dont recall ever seeing an amplifier made for specifically a 2.67 ohm load youll end up getting around 1300 or so watts because of the slightly higher impedence (2.67 vs. 2 ohm) those subs will be slammin and will be safe

Answer 4

you are correct it would be exelent but i would find an amp that is 2 ohm stable with about 1200 watts or you could find 3 amps that produce 400 watts at the ohms you want this would be cheaper because when you buy 1 big amp they are usually very overpriced good luck

Answer 5

if the amp is 2 or 1 ohm stable that's the right amp. check out this web sight. www.the12volt.com/caraudio/woofer_configurations.asp ... it will answer all your questions dude. i also had kicker comp vr subs i had one 12" and one 10" and i used a mtx 400 watt 2 ohm stable amp it was rated for 2 ohm when i contacted them and asked them if it would be bad for it with two sub they told me it would be fine and that they under rate their amps and it was 1ohm stable and i got 800 watts out ov it. man i was totally deaf.

Answer 6

Hank,

Are you testing us? Why are you asking questions if you are on point!!!!!

Of course you know that you will not find a amp rated @ 2.67ohms of if you were to buy an amp and needed 1200watts @ 2.67ohms it would have to be a mono block rated at 1602watts @ 2ohms to give you that same power.....

1200watts.......(x = Desired Wattage)
------------......X.....--------------
2ohms...............2.67ohms

2x = 3,204watts
Desired Wattage (x) = 1,602watts @ 2ohms

Sound good? Sorry if the format is a little jacked up but you get the idea....

Answer 7

your considering continuous power, now you have to consider peak instantaneous. if your amp can't deliver clean peak power then you will get distortion on bass drum because the amp will over drive and cut off the peaks of the signal. the amp ratings should include its peak power capabilities

Answer 8

that is exactly right but if you wanted to you could go a little over the RMS but i wouldnt reccoment going much over at all
