What are the speaker sizes in your 2001 Saab 9 3?

Answer 1

In the 9-3 you have 3 1/2 inch speakers up on the dash. The cover just pops off with a flat head screwdriver. The rear speakers in the hatch area are 6x9's. And in the doors are 6 1/2 subs. All the speakers are 2 ohm speakers. So if you replace the speakers and keep the rest of the factory stereo make sure that you upgrade to 2 ohm speakers such as Infinitys. If you upgrade to 4 ohm speakers, which most speakers are, you will get less volume out of your factory stereo. The reason behind this is that the car's factory amp will then be placed at a 4 ohm load which will cut the power output to half spec. Less power, less loud music. And you will notice a big difference.

So that's it. It is very easy to replace the speakers on the Saab so do not worry. You do not need to be a pro or anything.

Comment re: answer. I have a 2000 9-3 and the factory rear shelf speakers were clearly marked as being 4 ohm speakers. So I'd be careful about assuming they are all 2 ohm. In fact, the front door speakers are 2 ohm and the rears are 4 ohm. This link (toward the bottom has the ohms for each speaker: http://www.mitt-eget.com/saab/faq_audio.shtml#as2_amplifier The base is "Premium" and "Prestige" is the better sound system. I installed 4 ohm in the Premium rear and they seem to be working great. New Comment: My 2000 9-3 Convertible has 4 ohm in the doors and 2 ohm (6.5 inch) in the rear. The rears are cheap-ass whizzer cones with an itty-bitty second order crossover.
