original amplifier, subwoofer) audi a4 b5 NOKIA tda8563q description of cables,

Hello I have a4 b5 as topic needs help with this amplifier because I want to cheaply try to change the tube (change the speaker to add a second), but when I unscrewed the tip from the rest appeared to my eyes like the pictures below.
and now the question is:
from what every one is or does anyone have such information I noticed that the cubes come out two cables not connected (insulated) BLUE and BROWN
why I did not know what my predecessor made (the speaker also changed) I know that the amplification has 2x40W maybe there used to be 2 speakers

here he adds photos

There must have been a two-celled speaker there.

ok thanks, but I'm going to pull on a topic further what to do to improve the system a bit, I read a little and the two are so that the lower quality of the taste more squeeze like this? but I do not know if I understood correctly, can I buy a better gloss plug and connect to these 2 channels at the same time is possible such a bridge? and maybe 2 singles. insert an appropriately enlarged mailbox into ori place. or dwuczwkowy must be?
As I wrote in the first post I want to cheaply improve what to do
I know a lot of questions, but I'm curious if I do not have fun (oiling) -> although I would like the cubes and cables to be able to be turned back.
and I forgot to add I have not ori radio was a concert of blaupunkt (I was already pissed off) although it was great fit now I have a jvc with a 4x50 mossfet, and I can connect to the radio some other flavor and chest, and what with the back speakers at the door how to connect them or leave on the old end without a speaker ori?

For clarity, 2 coil speakers are used for two reasons: to achieve more power (speaker powered from 2 channels) as well as for ease of configuration with strong amplifiers (2x2ohm speaker can be combined in 1 ohm or 4 ohms).

The single-coil driver does not save you because you can not bridge this amplifier. Power 2x40W at 2 ohms is also overstated due to the measurement at 10% THD. The original loudspeaker was probably 2x2ohm for the best drive.

You can insert 2 single-coil speakers (2ohm for any power) if there is one.


You can also use a separate amplifier (the need to route the power cables from the battery and the signal from the radio.

As for the speakers from the back door, I understand they are powered from one TDA amplifier shown in the picture.

Since the radio is changed, you can properly tether the cables (behind the radio and at the amplifier) and power them from the new radio or power from the existing amplifier (I do not know how to connect with the radio).

will be hard with this 3 option what you wrote I am willing to throw the sub ori along with the whole package leave the tip on the back in the door and pull the new cable from the radio to another and other jigsaw I will assemble in total thanks for your interest I will need a little help in choosing an aftertaste and loudspeaker so that it does not make the plots (booty, booty) only plays well

Thanks for info.trochę me was not (two kids) dismantled tda led new cables for the rear door and front doors for new speakers, mounted a 2x500 magnate empathy something I bridged the tube and game connection (thin budget - and again on these children) topic I think it's finished

Hello,
and I have a question for you, I have the same amp drawn from the subwoofer from the audi a3. I run it according to the descriptions on the internet, but it sounds very quiet after connecting the low-level signal, it's good to start playing at a high-level signal. Is this normal for this layout? I am asking because on the connection diagrams of this amplifier it was written that the signal should go low-level. pzdr
