Need help before starting my project (Audi A4)

[Diexcy]

Hi everybody!

I'm getting my driver’s license in about 2 months from now and I just can't drive around in a car with stock sound system, it’s just not right. Started looking for some ideas and such I found this place and recently started reading a lot and following interesting builds. My parents got me this pretty sweet Audi A4 -99, which I’ll be using for at least a couple of years.

I will sooner or later with the help of my dear father build something much nicer than what’s in it right now. Needless to say we don't have any experience at all of building powerful systems and what not, however my dad is very handy when it comes to building with wood and other gooey materials, and we both got some creative ideas every now and then.

Right away when I got the car I had to get something to start with so we went to the nearest audio store and got this:

JVC KD-R411 head unit

JBL GT5-A3001 amp

JBL GT5-1204BR box

I haven’t played the system too many hours and after setting it up and tuning it properly it sounds about pretty damn good for an amateur like me. I'm very satisfied but of course I want more!!

I'm a pretty smart and quick learning mf, all I lack right now is knowledge

So far I got 2 ideas of how to do the next upgrade, both involving getting one more '12, of the same kind obviously, and sealing the trunk off with a wall

like TheScottishBear is doing:

Now where the ideas differ is if I’m going to build one more wall in the middle of the trunk and seal everything within it or build a box which I put in there instead. And I’m thinking of having either one or two ports going up, out where the rear speakers are right now.

Since I’m from Sweden i don’t know the name for it tho xD

So before I go and buy the shit to later on realize I screwed up, I’m looking for some feedback and advice on how I can build and what I must not do.

My camera broke for some reason the first time I actually needed to use it, so I had a hard time getting these pics with my cellphone.

Lets get some pics up in this b

Here is where I plan on having one or two ports, depending on the structure of the box, which I don't know shit about right now.

This is how it looks right now, well actually you can't see any of it when the seats are up Btw I don't like wires haning like that either and I wont even bother with making up an excuse right now.

The view from outside of the trunk

And finally a couple of pics of the amp, mounted in the trunk ceiling or whatever you wanna call it.

I appreciate all the help I can get right now

Also when Ive decided on what to do and start building Ill make a new thread in the member builds section.
