|  Car Speaker Help :) | mouseypoo Sep 12, 2001 5:33 PM | | Hi my question is a pretty general one. My cd player says 45x4 on the front of it. Currently i have two 140w speakers in the front
What is the cutoff wattage for each speaker if i were to get the highest wattage for the cd player i have? Like what is the most juice i can get out of one back speaker? without getting an ampliphier
thanks so much,

I doubt you will be able to turn up your deck much more than half-way before the amp begins to clip (distort), and possibly damage your speakers.
If you have good speakers,I would find an amp to match the RMS (continuous) power rating of the speakers, maybe even a little more.
Cheers,

First off I think car audio wattage specs are the most exagerated in the audio realm. your head unit has a wattage rating of 45x4. that means each speaker will recieve 45 watts. Now remember that is peak power. the wattage rating that actaully means something is RMS. the difference between the two is that rms is the constant amount of power the amp can put out for a long period of time. And peak power is the amount of power it can put out for short durations. The problem is that most car decks use tiny little amplifiers inside so they are quite limited in RMS cabability and will distort way before your speakers do. Even the amount of bass you add(loudness control bass controls) will reduce overall output and quality of music. The actual Rms output of the car deck is about half or less of the peak output. the same will hold true for most speakers and seperate amps. |
