Hi guys, I am about to do a full audio system upgrade on my Superb II which came with "Premium Sound". 

 

Story so far....

 

When the car is parked, the audio system sounds decent (not good). The bass (not mid bass) is lacking though. I have owned a ford falcon with a standard audio setup (6 speakers) which sounded better than this. However when the car is moving or stupid noisy Australian roads, the road noise kills everything. I have had a shot at reducing the road noise but with little or no result. I applied dynamat to the wheels arches and filled it with a layer of nylon. I also filled the hollow cavities over the wheel arches with expanding foam. This all had little of no result :(. 

 

Then I got a sub installed (pioneer wx710a) which didn't help either. It is way too boom than punchy and I prefer punchy. 

 

After throwing good money down the drain, I have come to the conclusion that the only way to make it sound better is to throw more power to the speakers and get better speakers. To this effect I am going to replace all the 10 speakers with after market (jlaudio post probably)  speakers. The problem is I don't know how. 

 

After having done some research I have figured out that my head unit (RNS510) can give line level out and because it is connected to an external amp (being premium sound) it is already doing that (so no need to go into VCDS, which I know nothing about).

 

Now the big questions, 

 

a) Can I just simply screw out my existing amp and connect my headunit to a new amp (I am assuming their is power coming to the existing amp so I basically use that to power my new amp and the signal is coming to the amp as well so just use those wire)? Another thing I have noticed is the line out from RCA is only 8 channel and that the amp does the split to 10 channel, is this really the case?

 

Has anyone ever removed the front door card, if so can some one point me to the right direct (photos would be much appreciated).

 

c) The set of speakers I am planning to put has a 4" mid range while my car comes with a 3" mid range, is there enough space to install a 4" mid range in the cavity.

 

 

Have you considered headphones?....

Yes I actually have a pair of M4U PS2, but I keep them at work can't carry them around 

Try just new speakers first before all the other expense. You'll need them anyway if you are going to upgrade 

 

The reason I say this is from experience with other so called  'premium' cars where actually the system/amp etc. itself was OK but the speakers were terrible and letting the setup down.

 

I am on the cusp of doing it with my car but not sure on which speakers to get. Macaudio I have used before and they were good.

 

Be interested to see how you get on.

Check your tyres for sawtooth wear as this makes for very noisy driving, even on good roads. It's also worth checking what the noise rating of the tyres you're running is. The noise difference between the 73 db Kumhos I got my car with and the 71 db winter tyres I'm running at the moment was unbelievable. The summer tyres I'm ordering soon are 67 db, so they should be quieter again. Ireland has no shortage of roads that are in bits, so tyre noise issues are very familiar to me.

 

Removing the door card isn't too difficult. There are two obvious bolts at the bottom of the door. The rest are accessed by popping the electric window panel (2 bolts) and the lock/tweeter panel (1 bolt). After that you lever it off starting at the bottom (The card hooks over the window sill). There are 6 stupid 'one use only' type plastic connectors holding the door card on which take quite a bit of force to remove but can be reused if you push them back in carefully. Use plastic tools to avoid scratching anything.

Had my tyres recently replaced with Yokohama Advan db. Didn't make a huge difference (just lot a little bit of grip ). At first I am also think of just upgrading the speakers and  it is turning out to be a pain. So far I have narrowed the options down to Jlaudio C5-653 for the front as these are three ways and C5-650 for the rears. Now the problem is 

1) They don't sell them downunder in straya (with us being a backward nation etc etc)

2) The mid-range driver on the C5-653 is a 4" while the factory mid-range is a 3" and there really is not a lot of space in there to mount it.

 

Was previously looking at focals but a good friend warned me against them. Can't think of any other set of speakers that would match these at the given prices point. 

 

Any suggestions?
