I have a 99 audi a4 with the bose concert cassette face and the cd changer in the back of the car.
I love the look of the stock unit but the sound is not very good at all.

If I add an aftermarket amp and speakers to the existing headunit, will the sound improve quite a bit or will it just be a louder version of what I have now?

I have read many reviews on this board and some people say upgrading the amp makes little difference while some people say there is a dramatic difference.

I have an alpine headunit, 2 channel zapco amp, 4 channel fosgate amp, 5 1/2 mb quart components, 5 x7 alpine rears, 2 12" kicker solobarics, cap, wiring, etc.

lets say I forget the alpine headunit and just use the 2 amps running off the stock headunit, how would I go about doing that.
My idea was to power the front mb's with the zapco 2 channel, use 2 channels on the fosgate for the rears, and 2 channels of the fosgate for the subs.
This is essentially what I did with my alpine headunit, but obviously that has 3 pairs of rcas in the back.
Is this even possible with the headunit?

Any advice would be greatly appreciated
thanks,
Eddie

Did you ever switch the settings for the headunit so that it acts like a standard unit, and not a bose unit??

Eddie3dfx

no how do you do that?

You need a VAGCOM. It will allow you to change the settings.

i have the bose and added a subwoofer, and i am happy enough... otherwise, you pretty much need to gut and replace everything to make it sound right....<ul><li><a href="https://www.audiworld.com/tech/elec44.shtml">one writeup about just adding an amp</a></li></ul>
