How do you know what audio system you have?

Don't replace with stock, you can fit infinity, Alpine, MB Quart in place of stock speaker and get a massive sound upgrade, as easy to do as replacing stock and almost certainly cheaper.

Hi all,

I don't mean to Hijack this thread, but, don't really want to start another for a similar subject. I too have the 490 option code on my 2003 base model, with a CDR23 head unit, and I guess woofers in the door. Stuttcars lists the 490 code as Sound system (Harmann analog), does this mean the system is connected via the MOST bus or not? I want to replace the head unit, and, crutchfield advise to just wire the speakers directly to the harness, or will the Metra 70-1784 Receiver Wiring Harness suffice??

Regards,

Jake.

P.S. this is my option sheet:

Jake - I have a 2004 Boxster S with the 490 option (Sound system (Harmann analog)) did you ever determine if this uses the MOST buss or were you able to replace the CDR-23 radio with something more current without having to replace the amp? Thanks - Rick

I just did a full blown upgrade.
Hertz 3 way components, pioneer PRS 80 head unit, Alpine pdx 9 amp.

Used the metra plug from crutchfield had them do the prewire for $20 head unit plug and play. Dash speakers used CAI speaker kits, bit pricey, but makes installation a breeze.

For door speakers they will hold 5.25 direct bolt in, but they are subs so unless you change amp will only get low freqs. I put 6.6” in by buying and modifying speaker box from ebay. Truth be told change hu, and dash speakers will improve sound by tons. A single din fits so you can go back original if you sell.

As an aside...

I found that having the windshield tinted (lowest tint possible), with a higher grade UV tint, near eliminates not only the UV... but also the heat. I had tint installed on my Edge a few years ago. Night and day difference. Tinted the Boxster days after purchasing it.

Protects the leather dash and interior... and saves those speakers from drying out.

Just my $.02
