New radio installed question

Hi Everyone,

When my radio stopped working for some odd reason I thought, great, now is the time to have satellite radio installed which I had grown accustomed to having in my truck. So I had an Alpine - 50W x 4-Channel with SiriusXM Satellite Radio (Model: CDE-124SXM) radio installed into my 2001 Boxster that came with the factory 6 speaker set up and amplifier. I didnít change any speakers or the amp as I thought they sounded great (not the best but certainly good enough for me).
The factory speaker set up in my Boxster has 6 speakers - 2 behind your head, 2 in the doors and 2 in the dash and factor amplifier and (NO SUB).

Now the new Alpine radio is installed(had indy shop put it in), they seemed to have wired my dashboard speakers as the front speakers, the rear speakers as the rear speakers and the door speakers as the sub speakers so basically, I'm not getting full sound because now my door speakers which used to kick pretty hard(or at least good enough for me) RARELY come on. When the old radio was in, I donít ever actually recall hearing any noticeable sound from the dash speakers. Any insight or thoughts would be appreciated. Iím wondering if the indy shop, while they do great work on the usual Porsche stuff, wasnít sure how to wire the radio correctly? How do I correct this? Right now I only hear the dash speakers and rear speakers, the door speakers rarely add anything to the sound and I have adjusted the radio settings over and over again, they simply arenít putting out much sound if any. During most songs they contribute nothing.

Hi Josh,

Just a guess but it 'may' be that the Alpine has a low frequency crossover network in it that allows only very low frequencies to pass to the door speakers. These would be frequencies that are too low for the door speakers to replicate. I am guessing that what you DO hear out of them are the higher bass freqs. that the Alpine is sending to them, and you only hear whet they can reproduce.

Again just a guess, not etched in stone.

Good luck,
