Default Hello, need some help with audio!


I have a 2001 Saturn SL1 I recently put a new stereo in my car and it blew my stock speakers. I have a Pioneer DEH-P4900IB stereo. I'm wondering what wattage of speakers I would need that won't blow. For the doors and the trunk part.

http://pioneerelectronics.com/Static...P4900IB_OM.pdf.

Specifications pg 37.

Audio
Maximum power output ....... 50 W × 4

Continuous power output ... 22 W × 4 (50 Hz to 15 000
Hz, 5% THD, 4 Ohm load, both channels driven)

Load impedance ... 4 Ohms to 8 Ohms× 4
4 Ohm to 8 Ohms×2+2 Ohms × 1 (subwoofer)

------------
So at least 50W speakers for the doors. I'd go a bit higher, because the day will come when you bump the volume to max and destruction will occur before you can do anything.

4 Ohm or 8 Ohm (a measure of a device's resistance to passing electrical current through it) are fine. 4 Ohm speakers are easier to pass current through but V=IZ (Z-impedance), so it requires twice the current from the amp to produce the same volume as compared w an 8 Ohm speaker.

I changed power to ohms in the impedance section because power is not a traditional way to express the impedance (P=IV))

--------

This is all in your owner's manual. If you didn't have one--now you do.

Don't know if the car came w a subwoofer or just extra speakers in back.
