I need some HELP with Rear speaker kit - 986 Forum - The Community for Porsche Boxster & Cayman Owners

sounds tough but worth it.

When the top is up I fade in the rear speakers (60-70)

When the top is down I use only the front speakers. I have the 'premium' sound package with the DSP thing on the dash, door speakers and dash speakers and tweeters and the four channel amp. With the top down going at 70+mph its as good as any convertible system I've ever heard. Having full wind deflection helps enourmously.

with the top up during winter not having the rear speakers was really irritating. The previous owner never had them wired! I bought the PNP kit from Harvey on Ebay needlessly,I had speakers back there all along.

the only problem with great sound in the Boxster is that I can't hear the engine!

p.s. the Wall Mart polyfill stuffing behind the rear speakers helps. Its like $3 for a large bag, more than enough.

You don't have to feed the wires to the front of the car's dash the way they tell you to do it if you don't want to.

I installed the rear speaker kit myself and just ran the wires under the carpet piece behind the passenger seat and along the passenger side of the center console by tucking them up under it until I got to the dash.

Completely invisible, looks fine and works fine too. I had no desire to unscrew the door sill and all those silly plates and things to do what was suggested online.

Concerning the wires themselves, I believe you will find that the brown connector fits perfectly in the back of your head unit and the bare wires go to the speakers in the back.

ok I got the speakers to work by just plugging it into the amplifier on the outside, without going through the firewalls. I guess I have to directly connect to my amplifier.

Now, does anyone know how to route the wires from the amplifier in the front trunk to wear the rear speaker socket near the roll bar?

Your system may be different, but I plugged my rear speakers directly into the back of the head unit, not the amp.

Yes, the 2003-2004 models require to be plugged into the amp. We dont have a radio code either.

Well, it looks like you're going to have to go through the firewall. Bummer.

I bet it's hard to find and do the first time and thereafter not nearly as hard... not like you'll ever do it again, but hey, I'm trying to be encouraging here!

On 2003/4 the rear speaker kit is wired to the amp, because the amp is 6 channels and 2 are for rear speakers.

Remove the battery clamp and slide the battery to the passenger side. Behind the battery you will see a large black rubber plug. Get an ice pick and stick it in the middle of the plug. Then look above your gas pedal for the end of the ice pick. You will see than an X has already been cut in the insulation for wires to be pulled through that plug.

Then pull back the carpet in the trunk where the cd changer is supposed to be. You will see another plug. Make a hole in the plug for the wires. You pull your wires through both plugs and over to the amp connector.

This is how we route wires from the interior of the car into the front trunk.

To go from the roll bar to gas pedal you have 2 choices. Route the wires down through the center console to near the radio head, or route them via the passenger door sill. We did it the second way and when we filmed the rear speaker intall that is the way Porsche says to do it.
