I have the M490 sound option in my 2003 MY04 Boxster (6 channel amp, speakers in dash and doors). The car was delivered in Australia. Planning to replace the 4 speakers with something like Focal 3 way separates such as the K2 Power 165 KRX3. The bass driver would go in the doors, mid and tweeter in the dash. The appeal of this is that all 6 channels of the amp can be used (I don't plan to put rear speakers in), driving one speaker each. Questions... Does the original 6 channel amp have a built-in crossover? If so, what is the frequency point of the crossover? Does anyone see a problem with this idea of installing separates? Cheers.

Hey guys, Really appreciate your comments and references to upgrade work done by others. yellowlemon, it's a bit of a drag for us to fork out more and have to import some of the good kit isn't it? Price we pay for living at the bottom of the earth! JayH, those Hertz speakers sound like a good option. Agree that metal domes are often too bright in a car. I'll try to find a stockist here and have a listen to them. I'll skype Rod and see what he suggests too. DaveS, those Infinities look to be very efficient (93 dB @ 1W) and good range too, however they are 2 Ohm impedance. I'd expect that the original amp I have could well overheat driving such a low impedance load. I'm working on the assumption that the stock speakers are 4 Ohm nominal impedance. Cheers, Geoff.

Fellow Porsche fanatics, Planning to replace the factory speakers fitted in my '03 (MY04) Boxster with higher quality items. My car has the M490 sound system fitted - dash and door speakers and the separate amp. Original head unit. Rear storage compartment fitted, but probably won't install speakers in it. Questions: 1. Are the specs for this amp 6 * 40W RMS into 4 Ohms? 2. Are the two channels that drive the door 'subs' (I use the term loosely) crossed over and therefore only sending low frequencies to those speakers, or is a full range signal transmitted to them? My requirements are: - Good sound quality (fairly neutral) is more important than high volume. - Want decent bass (tight and musical rather than boomy). - Music is a mixture, but I mostly play rock. There isn't much below 50Hz on most CDs I listen to. - Must retain an original appearance. - I don't plan to put a separate (additional) sub in the car, although may consider putting one behind a seat. - Cost of the speakers not really a consideration. 3. Given the above, what are some good choices for the dash speakers? Would the Polk 401s be the best choice for me? I'll probably replace the existing door 'subs' with better ones or some full range speakers that produce good bass. Obviously small speakers aren't going to reproduce low frequencies very well. 4. What are some good choices for the door speakers? 5. Are there any speakers of the size (5.5"?) that don't require mods to the doors that go down to about 60Hz at say -3dB? 6. What is a good online e-tailer in the U.S. that will ship to Australia? (I expect some suggested speakers won't be available here) I've read the many posts describing various stereo upgrade options on this forum including AndyM's excellent diy guide. Any suggestions would be greatly appreciated. Cheers.
