  1. Does it mean you connect the sub directly to the Pioneer head unit? The Alpine MRP F300 looks good to me and runs with 2 Ohm speakers! Thanks, Marco Marco: On the filter question, "no", and to us the sound is as good or better than with the CDR23. With regard to the sub, the amp does not have a direct sub output, but rather a RCA output to feed another sub amp. Since the Pioneer head unit has a direct 50W subwoofer output, I am going to at least try running it straight from the head unit. Hope the weather will cooperate for doing it this weekend.
  2. Marco: I'm by no means an audiophile, but was looking for more capability than volume and sound "quality". However, so far my wife and I are more than satisfied with the DIY job of this weekend. I installed an Alpine MRP F300 amplifier (75W per channel) mostly because it fit nicely to the left of the exisitng BOSE amp (if you want more power at twice the price the Alpine PDX 4-100 appears to fit there as well) and was an easy connect to the battery. I spliced the existing speaker wires from the BOSE amp harness to the Alpine (dash and door to "front" and rear to rear per the schematic).
  3. Can someone confirm the ohm rating of the Bose speakers in the 2003 996 coupe (M680 option)? Appears that they are 2 ohm, but can't confirm on the speaker.
  4. Loren: Sorry, 2003 996 coupe. Trying to replace existing head unit and amp, but use existing speakers.
  5. Does anyone have a speaker schematic for the M680 Amp/speaker system?
  6. It does take special tools to take out the radio. You can find them on Ebay for about $.99, but then pay $5-$6 for shipping. This is where I got mine. Once the radio is removed you need the code to reinstall it, but it you are upgrading this doesn't matter. The Most system is the big challenge. By the way, if you are keeping the stock speakers you won't get much improvement from a new head unit. The speakers are the weakest link in the system, they are crap. Start with speakers, then an amp. Last step should be the head unit. Thanks for responding. Hoping to do this in two phases - first ge
  7. It appears that many of you have experience in replacing the factory radio. I recently bought a 2003 Carrera 996 coupe and want to replace the CDR23 with more capability. I'm looking at a Pioneer DEH P7900BT with a Sirius tuner. However, after reading many posts on the site, I'm not clear on whether I have to have special tools (or the dealer) to remove the CDR23 and/or reset codes after removal and whether I can somehow continue to use the Bose Amplifier (M680) due to the MOST system, or need to add a new amplifier as well. Would appreciate any experience and guidance in this area, especially
