CDR220 upgrade

Filed under: Stereo,Uncategorized — Jeff 993TT @ 6:06 am

You can use the CDR220 from the Boxter/996 in your 993.

In order to do so, you will need to update the face plate so you can see the display. It’s polarized for the boxter/996 and you will not be able to see it in the 993.

The cost is $50. Contact the part deptartment of Becker here:

While you are at their site, you can order an AUX IN cable and also the removal tools.


Speaker sizes

The factory front speakers (non Hi-Fi option) are 5.25 “, but the bolt circle to fix them is oddly sized. It is very large compared to a number of mainstream speaker manufacturers. But it is slightly smaller compared to common 6.5″ models. The stock grille is big enough for many 6.5″ door speakers sizes.

The Hi-Fi package front speakers consist of 5.25″ midbass/woofer, 3.5″ inch midrange and 0.75” tweeter.

The rear deck speakers are 4×6 component speakers. Mounting depth of at least 53mm is available. There have been references to fitting up to 6×9 rear deck speakers.

Radio code

Filed under: Stereo — admin @ 5:41 pm

The stock radio installed in Porsches have an anti-theft device. If the radio or battery is disconnected, the radio will disable itself. When either one is reconnected, the radio will ask for the code in order to function. The display will read “CODE”, with a flashing letter “C”, and the digits 1-0 appear. Simply enter your code and then press the seek button to use your radio again. If you don’t know your code, look in your manuals to see if you still have the radio code card that came at the original purchase. If you can’t find the code, call 800-Porsche, give them the VIN #, they should be able to give you your radio code.
