Amp for subwoofer

[Jacket]

I've got a Pioneer subwoofer in my 80 that is advertised as having 500W max power and 120W nominal. 4 ohms impedance. Since I hooked up a new head unit recently, I'm now bypassing the factory amp and the subwoofer now needs it's own power.

I got an email today about a deal on a new Kenwood amp. It's a 2 channel amp that pushes 60W per channel RMS @ 4 ohms, or 150W bridged at 4 ohms. $69 with free shipping.

Since 150W is slightly higher than the 120W nominal on the subwoofer I own, is this a bad combo (risk blowing the speaker), or is it "close enough?"

First of all what blows speakers typically is distortion. Distortion from under-driving (not enough power) a driver (speaker). Bass drivers typically require a lot of power to overcome limited cabinet space. Having a higher output amplifier simply gives a lot of reserve you may not use.

Having said that if the amp is 150 watts RMS then it will work totally fine with the pioneer.
