Key Specs
RMS Power: 60 watts (The maximum amount of continuous power the device is able to handle.)
Peak Power Handling: 180 watts (The maximum amount of power an electronic device, like a speaker, can handle without damage. This refers to short bursts of power, while root mean square (RMS) power handling indicates the amount of continuous power a device can sustain. Higher levels of distortion can also occur at peak power levels when the device is powered beyond its recommended usage.)
Minimum Frequency Response: 52 hertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The minimum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
Maximum Frequency Response: 22 kilohertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The maximum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
Sensitivity: 93 decibels

Quality upgrade to OEM sound
While I will admit entry level factory installed systems have come a long way in recent years, the stock speakers are no match for these Polks. Volume is not the true measure of quality, its a measure of a speakers efficiency, how many decibels of volume from a watt. I would wager that the stock speakers are more efficient, which may equal more volume, but not quality. So if your looking for a "I used to turn it up to here, now I have to turn it up to here, these speakers don't JAM" type review, then you may want another opinion. These speakers are NOT as loud as stock speakers, they are also not as distorted, produce FAR better mids (where most of the sound is from) and wonderful crisp and less painful highs that are much less ice-picky. Car interiors are made to be less quiet now and don't require the volume to be turned up as loud as they used to. The Polk Audio DXI571's are excellent sounding speakers that still get plenty loud but produce clarity and quality of sound that entry level stock speakers IMO, can't touch.

great sound
The sound is great. I have a truck that only has 2 spots for speakers. Now that these are in it sounds much better. I listen to classic rock and the drums and guitar sound right on.
