I need to use the power of the forum member base as I am very tired and seem to be failing miserably at finding the correct speaker sizing for a friends car. So can someone help me find definitive speaker sizes for:

2005 911 Carrera S Cabriolet

With or without Bose?

Upgraded audio at all?

From this website CLICK ME! it appears as if there is a standard, upgraded, and Bose stereo option.

I would say an 8 inch sub would be good. Then again how much room are you willing to sacrifice to on the ride? That is another question and take into consideration room for amplifier and other audio goodies to.

Standard Sound Package Plus

Standard on PCM is a Sound Package Plus, which includes nine speakers with three times the usual transmission area and with an external analog amplifier for outstanding sound in all driving conditions. The system includes two .75-inch (19-mm) tweeters and one 2.5-inch (70-mm) mid-range speaker in the instrument panel, two 4-inch (100-mm) mid-range speakers and two 8-inch (200-mm) woofers in the doors and two 4-inch (100-mm) wide-band speakers in the rear section of the passenger compartment.

The external analog amplifier is located in the luggage compartment and supplies the woofers in the doors and the mid-range speakers in the instrument panel.

A six-disc CD changer is available as an option.

Optional Bose® Surround Sound System

Also available is a Bose Surround Sound System with 13 speakers and a seven-channel digital amplifier integrated into the digital MOST bus to ensure outstanding sound quality.

The heart of the Bose Surround Sound System is a digital amplifier with a 5 x 25 watt output and additional support from integrated and external 100-watt switching terminals. Active electronic equalization adjusts the reproduction of sound to specific acoustic conditions so all passengers enjoy a sound experience.

The system includes Bose's AudioPilot technology that automatically adjusts frequency levels to compensate for wind, road and traffic noise inside the vehicle. A special microphone in the steering column cover picks up such noises.

Speakers used in the Bose Surround Sound System are Neodym units that are more compact, lighter and have better performance than conventional speakers. A Neodym iron boron magnet generates a magnetic field 10 times more powerful than a conventional speaker magnet.

The Bose Surround Sound speakers include two 1-inch (25-mm) tweeters and one 2.5-inch (70-mm) mid-range speaker in the instrument panel, two 3-inch (80-mm) mid-range speakers and two 8-inch (200-mm) woofers in the doors, two 1-inch (25-mm) tweeters and two 3-inch (80-mm) mid-range speakers in the rear of the passenger compartment and one active subwoofer with two 5.25-inch (130-mm) woofers in the rear parcel shelf.

I believe it has the standard system. The car has very little options from what I understand, outside of the "S" upgrades.

Thanks, man those are some awkward sizes.

I believe it is just a pair of tweeters in the dash and 6" woofers in the doors. Capacitors on the tweets nothing on the woofers

I think it might just be best to get stock replacements for now.
