Hello there!

I have just installed an Parrot Asteroid head unit in my B5 and it works out great!
however since i bought the car i have been hoping for some better speakers for the rear parcel shelf.

The car is an 98 A4 B5 saloon with Audi Concert II with bose speakers. (All stock except head unit)
for my ear the door speakers is decent enough for now, but the "woofers" in the rear parcel shelf is somewhat rattling and cant keep up with the door speakers if you push the volume a little, i think they have been damaged over the years.
i have been searching for a while now but i cant seem to find out if there are any good replacement speakers for the shelf?

I was hoping to get some speakers that i can connect to the bose stock amp that is a little bit more powerful and punchy and will fit in the shelf whiteout any major modifications.
something like this exist? all i miss from the sound is just a little more punchy bass from the rear, that can keep up in volume with the door speakers.

From what i have found out it is 6,5" speakers running at 2ohm.
i got no clue if this is subs, or mid-bass?

So any help will help me out alot!

Also now i just want to replace the speakers with some better ones, and maybe later upgrade the whole system, but for the time being i don't have the time or money to do it.

Also i hope i post this in the correct forum :) i will make a thread later on the car, since i just made my account here. Just been member of the Norwegian vw audi club so far!
