First,

I've searched for about an hour and all I can find are people with issues pertaining to the headunit, amp and rear speakers. I'm looking for instructions or directions. I've done headunits before, but it seems like an Audi is gonna be a bitch and a half.


Headunit- Sony something or other, used it before, really liked it. 52w output, made enough difference.

Amp- Alpine amp for speakers

Speakers- Alpine type Rs for the rear deck (one speaker is cracked)


This is what I need:

-A headunit in dash holder
-a wiring harness (if available for the audi a4 b5)
-and any help I might need


Thanks guys !

 

go to installer.com and get the amp integration wiring harness got to best buy and get the dash kit i would have them do it (best buy)cuz it is a bitch but its up to you speakers are easy just unplug the factory and solder the new ones in but do it if you know how to only

 

You shouldn't have to replace the amp just if the speakers blow, just the speakers themselves. I still have my original bose spaekers but wouldn't be able to get to them for a few months (cuz they are in storage til I buy a house)if you really wanted to just replace them with speakers that will blow again.
Like most things audi, it can get expensive. I had a couple bose blow and decided to just replace them all. There are kits to make bose speakers work with aftermarket stereo (which is what I did at first plus an amp and 12" sub)but don't know about making your stock unit work with aftermarket speakers--guess anything's possible. The problem is the impedence of the bose speakers is 1 ohm and most aftermarket speakers are 4 ohm and most aftermarket stereos won't do 1 ohm either. If you want to just replace the speakers, you can do so and just connect them to a new aftermarket amp (cuz bose has a separate small amp for each speaker usually)and then get the bose kit/wiring harness to make them work with the stock radio OR just replace everything like I did and not have to worry bout any kind of compatability issues if they should arise.
Whatever you decide to do, I went with Focal speakers. They are high end and sound AWESOME and can handle way more power than they say they are rated for without having to worry bout them blowing. There are several different series and price ranges. I wanted sound quality over loudness and ended up getting both. They are crystal clear with any music and though were a little pricey, were worth EVERY penny! I'll never buy anything else again!
A couple good alternatives to the Focals would be the Infinity Kappa series, which are definitely less expensive but were a little bright for me but good none the less, or some of the new JL Audio components. Best bet is to go to a car audio place and just listen for yourself and see what you like. BTW, i also got a double DIN Kenwood(which I've always had great luck with) head unit that plays dvds, etc and looks great in the factory spot.
I was a stereohead before an audi fan so feel free to msg me if y'all have any questions.
ADDENDUM: Just went to have my kenwood pulled out(sending off to get couple buttons fixed before the warranty is up) and the factory put back in. The factory WILL NOT WORK with aftermarket amps. Has to do with lack of connections on factory unit and possibly Ohm loads but maybe not. They instead were able to hook up a cpl Yconnectors to all my indash wiring and now my whole system is temporarily rinning off the earphone jack on my iPOD!! Sounds great too!!!
