To remove the Bose sub box in the 2004 996 coupe - you first put down the rear seats then:

1. carefully remove the bose black surrounds on the two ports by pulling out from the top center/sides with your fingers -- note the plastic retaining posts bend/break easily -- ask me how I know...,
2. remove the center torx bolt below each port;
3. slide the whole box forward toward you/front of car;
4. detach speaker cable/clip on rear (driver's) side of box;
5 remove box from the car (I did not remove the rear seat receivers as in the Sharkwerks write up -- sub box removed easily w/o doing so in my case);
6 undo about 2 dozen or more small torx bolts;
7. separate plastic top and bottom of bose sub box;
8. remove 5.25 bose woofers and replace with your choice of 2 ohm JBL GTO series or Infiniti Kappa (or your other favorite high sensitivity/2 ohm speakers) in 5.25' or 6" size -- the 5.25 inch are plug and play, the 6 inch fit but you have to push them in to fit between the plastic sides of the box (held in place by the force only -- and I don't mean star wars luke)
9. add some foam to the sub box and/or dynamat (foam from Target twin bed mattress pad cut a few pieces to fit)
10. plug in your new speakers using existing wires (small clip is negative/striped wire, large is positive/solid wire)
11. Put all back together by reversing steps and pump it up.

You can look at the Sharkwerks ECU removal procedure which also requires removal of the bose sub box in the 996 w/bose: http://sharkwerks.com/porsche/techni...s-gt2-gt3.html

Today I removed the rear carpeting/foam from the rear of the coupe and used 2 layers of dynamat extreme over the rear deck, along with audimute peacemaker 2mm soundproofing attached with 3m spray adhesive to the stock foam covering (underside of the rear compartment cover panels). Noticeable improvement and reduction in cabin noise on the highway. Spent about 2 to 3 hours to do the rear compartment.

I downloaded a free dB meter called decibel 10th, for my iphone. At idle the passenger compartment is reading about 60 with peak at 65 db with air conditioning turned off. Around the block at speeds up to 40 mile per hour at 3k rpm DB is reading 72 with peak at 80 db. Highway speeds of 65 to 70 mph 80 to 84 db with 91 peak (going over bumps etc).

Don't know what it was before I installed the dynamat in the doors and rear compartment. But, any others with stock setup can download the iphone app and post your cabin specs to compare.

Next weekend maybe will do the same under the rear seats and front of cabin.

I find that the stock radio fits my needs just fine, what's horrific is the antenna and lack of reception range.

What did you guys do with the new radio antennas? Having a cab complicates things for me even more.

When I added an aftermarket head unit to my 996, the stock antenna was used. Reception was even worse with the aftermarket unit. FM was terrible and AM was almost non-existent. I mostly listened to Sirius XM.

Crap, that's not the answer I was hoping for. LOL

I'm definitely going to have to look at this later....

So, has anyone in here done the "add wire to the antenna amp in the A-pillar" to improve FM reception? The FM reception in my '99 cab has always sucked, and I'd love to improve it.

Still loving my ipad mini using bluetooth FM modulation through stock head unit. Keeps RDS display of songs on your rpm gauge. Using Spotify, Apple Music and Waze is awesome in your car!

Riad

Bwahaha that's awesome!

You got me thinking...

Now that Amazon has the Kindle Fire for less than $50 what would it take to install one in the car and use it as a music storage and streaming device? What did it take for you to put together your setup?

Riad

By the way they sell that trim piece for your climate control at the bottom.

Having a cab definitely lowers your options for subs, at least at a decent price.

Thanks that pic is before I finished it.

I am using the
The ipad is simply connected via bluetooth to this. I hacked a USB charger into my phone plug to charge the ipad. So when the key comes on ipad comes on when key goes off ipad turns off. You need it jailbroken to do this.

The 996TT We bought has a pioneer Dual Din head unit installed. along with a amp and cross over in the frunk. Dayton audio speakers (5.25) in the doors and dash (4"? and a 1" tweeter hence the crossover)

But the Rear Speakers aren't hooked up! I plan on trying some 4" coaxials with an extra amp in the frunk, and see how it sounds.

I could really use to remove the head unit to add an extra set of RCA cables for the new rear speakers/amp, and the AUX in cable while I'm back there(the Bluetooth doesn't seem to like high .

Will it remove the same way the OEM unit does? with screws in the side?

Or will it be held in with tabs etc...? It has the flimsy plastic bezel around it, so i figured there might be some tabs/latches hiding back there?

Thanks!

Has anyone installed the parrot asteroid smart in a 996 yet? Pics and feedback?
