Can my amp power these subwoofers?

-I have a Soundstream LW2 260 watt amp. Is this RMS? It must be because my subwoofer is 1000 watt peak.



Can that amp power these Kickers??



Do you think they will pound hard??

2 12" Kickers----- 750 watts peak power handling (250 Watts RMS)I disagree with the two previous answers.



When it comes to car audio the answer to "can I do this" is almost always yes. The real question is, would it be worth doing.



The box contains a pair of 4 ohm subs. They are wired parallel resulting in a 2 ohm load at the box's wire terminal. Inside the box it looks something like this: http://images.the12volt.com/12voltimages鈥?/a>



Your amp can only function at 4 ohms or higher when bridged. So in its current state you'd have to use only one channel, and each sub would get around 75w rms. Plus, you'd have to choose either left or right which would not be good for sound quality.



The best solution would be to unscrew the subs from the box and rewire them like this: http://images.the12volt.com/12voltimages鈥?/a>



That would provide an 8 ohm load. Unfortunately the power to each sub wouldn't change, but doing in this way would place a much lighter load on both channels of the amp, vs a heavy load on just one channel. On top of that you'd have the combined signal from both the left and right channels which is ideal for subwoofer sound quality.No, it will not power those subs. It will likely ruin them actually. That amp is only 60w RMS per channel. You need an amp that puts out between 400 and 500w RMS to power those subs.



With the right amp and right enclosures they will "pound" just fine.
you can not use that amplifier with the subs you linked to. the subwoofers are wired for a 2 ohm mono load. your amplifier only runs speakers 4 ohms or higher when bridged.
