Yeah...this should be an easy one, but I still need some help.

I have two subs, each 4 ohm, 250 watts rms. If I run them in parallel, that makes a 2 ohm load, where my amp will output 400 watts. Is this safe? I am confused if my subs can now handle 250watts rms or 500 watts rms.

Thanks.

Depends, what amp you have (most likely it's two ohm stable). I'm pretty sure everything will be fine.

Your subs TOGETHER can handle 500rms if that is what your asking. Each of them will get 250rms. The power between the subs will even out between each. As for your amp, will it be puttin out 400watts MAX? Or 400rms? If its 400w max, then your only putting out around 200wrms. Which is not enough for two subs that are meant for 500rms.

Just curious, what subs are you running?

Sorry, 400 watts rms.


2x Kenwood 10" kfc-xw1005db.

One was actually just damaged, gotta see if someone in town can fix it.

after you parallel the coils, how will you wire them to your amp? if it a 2-ch amp bridged, the minimum impedance will usually be 4 ohms......but if it is a class-D monoblock, then it would be able to run a single 2 ohm load....double check before you fry your amp

Cool, that setup should work good.

Yep, those subs handle 250w rms ea. So the two subs together will handle 500w rms.

Good luck on getting it fixed, is the VC blown, or is there a hole in the cone?

The cone has ripped away from the voice coil. I might try fixing it myself, glob a bunch of rubber cement in there and try it out. Or, I might see if I can find someone to fix it for a resonable price.
