Although I love the stock stereo, I believe its not performing up to par to what it should have stock. Two things mainly. One is the bass could be a bit richer, and two, there are vibration noises at a certain frequency in the front components.

As far as the bass issues, if you are not looking for insane bass, but rather just a slight improvment, this could be the solution for you. I ordered 40 square feet of sound damping (www.edesignaudio.com), same thing as dynomat or any other but better value and also a lot more stickier.

What I did was I undid the top lining inside the trunk, the panel where the subwoofer and the rear speakers sit. Then you will see a 2-layer aluminum chassis where you can see the magnet of the woofer. I put damping all around, inside and outside of the 2-layers, but not on the woofer or magnet. To say the least, it was a lot of deadening. Once your down, use a heatgun and heat it up to make sure its sticky and conforming to the curves of the chassis.

The results are not mind blowing, but its a huge improvement. The bass is a lot clearer, and crisper. It also sounds very rich after the deadening. I actually had to turn down the bass setting by a notch because it started to rattle something on a certain song, where it never did before. It was just a tiny, inaudible rattle, which I only heard because the car was off and there were no vocals.

Next will be the doors. I ordered a different type of deadening for that. I ordered a foam-type damping material because that will hopefuly eliminate the higher frequency nuisances.

Total cost for both were about 50-60 I believe. Enough for both front doors, and the rear subwoofer deck area.

 

which stuff in particular did you use? take any pics?

 

Sorry, I meant to say I used 10 square feet of the eDead V.1,
and 20 square feet of the eDead v4 teklite. I dont have any pics, but it's very simple.
Pretty much sticking thick tape onto the metal chassis of the car around the woofer to reduce vibration and some flex.

 

Help us out!

 

Sorry, I didnt really feel like it was necessary when I was doing the install. Plus I cut my damn pinky trying to cut the deadning so it was gushing all over the place. But here is a link that's pretty easy to follow. Not for the TL, but it's basically the same concept. I will try to get pics once I do the front doors.

Put on some of the remaining sound deadning around the front speakers, and also the foam matt on the door panels. Wow what a night and day difference. Virtually no rattles from any song. Huge midbass increase, and also a big increase in loudness overall. Treble and sharpness has also increased a whole lot.

Only problem i had was that I placed too much foam matt onto the panels and couldnt fit the panel back onto the door, so I had to remove a layer or two and try again.

 

I just bought all new infinity speakers for my o4 TL and I'm wondering If I'm gonna have any problems with the swap. I hear the TL's run on a 2ohm load? Also do I have to remove the hole panel or does the grill pop right off. Please help.

 

You will need to remove the whole panel. IMO infinities are a bit harsh, but let me know how it turns out.
