Just discovered your channel today, I'm an instant subscriber, your knowhow, skills and thoroughness to each of your video's, is fantastic. Please keep sharing more content on these lovely Audi TT's, this channel has so much information that is so useful. 5 stars sir 😊

[@ianpgonzaga]

Hey Alex appreciate the complements! Thank you for watching and i'll do my best to keep our TT's the best they can be! :)

[@markremi]

This is exactly what I needed for my upgrade. Hadn't come across one that was this thorough 👏

[@ianpgonzaga]

Glad it helped you out @mark!! Now you can enjoy your new, great sounding system 😉

[@stuartwinstanley4949]

The best video on stereo install iv seen thanks man

[@ianpgonzaga]

Thanks Stuart I hope you found it helpful.

I just run Apple CarPlay, Android Auto, Screen Cast, phone hands free & text to voice plus satellite view maps through my OEM Chorus head unit, all for exactly £100 and a 10 minute install including a stealth 12v socket. The actual installation is only 30 seconds, it’s reattaching the dash panel for the additional 12v socket which takes a moment.

[@ianpgonzaga]

What unit are you using to do this ?

[@EdouardoBernoulli]

Deh 80prs is the perfect 1 din radio it has auto eq and time compensation with a special microphone, I'm thinking of adding 2 speakers in the back of mine

[@ianpgonzaga]

Yeah I totally love it. Such a great piece of kit !

Ohh you are awesome! I've followed your restoration. Great job dude!

Thanks vicURc! It's definitely been worth the work cuz now we get to enjoy the car! Not only is the car cool but it's pretty quick too 🥳

Hi the aluminum TT cover can close with this radio?

[@ianpgonzaga]

Yes it closes

[@Aston_Keeper]

We struggled with the ground loop isolator, it didn't seem to fix it (it was an old one I found in a drawer) so we used line level adapters, which also aren't ideal. The bigger issue is we're getting nothing out of the rear speakers, I'm guessing I need to sit down with the loom diagram you shared and review the ebay special adapter as there's something crossed - Unless you have come across this?

[@ianpgonzaga]

Hey Classic Keepers. I think double check your wiring loom. Also is your system Bose or not ? Either way it does sound like - wiring is incorrect when using the line level adapter - HU needs fading to the rear (have you tried to see what happens when you fade left to right?) - rear speakers blown

[@Aston_Keeper]

@@ianpgonzaga yes it was the bose with a CD changer. I've seen that there are some front speaker only looms. It's had an amp change too so it's got to be the loom. I'll get on it, thank you!

[@ianpgonzaga]

@@Aston_Keepermine also had a cd stacker (mounted in the back) You want to make sure that the big 20 pin plug has the 5 wires coming out of it. Has a common GND

[@mikeevans4927]

Hi, Great video, a very thorough and professional install. I have bought a second hand Pioneer DEH 80PRS and intend to fit it and replace the existing speakers at the same time as they are somewhat worn out by previous owner/s. What speakers would you recommend as replacements for both front and rear? Cheers

[@ianpgonzaga]

Hey Mike. It'd a great HU and glad the video was helpful! I recommend anything 6.5" and with a shallow mounting depth. The door cards are very flat so you don't want to risk the magnet hitting the window as it moves. I'm actually going with some 5.25's because the roadster has a subwoofer to take care of the low end. I find they have smaller magnets too but great sound quality. Also I highly recommend doing the auto EQ thing with the pioneer microphone. It made a really big difference to the sound afterward. Cheers!

[@mikeevans4927]

So allowing for the speaker depth nothing springs to mind that would compliment the DEH 80PRS? Also I am toying with connecting the 6 stacker CD player back up as was disconnected by the previous owners to suit the alpine IDA x001, your thoughts?

[@eliteculture1519]

Love the video. I’m planning on upgrading my head unit, amp, rear and front speakers plus tweeters. Looking through a bunch of videos, I’m seeing that people are having trouble with the Bose amp. Would I need to rewire to all the new speakers to connect to my new amp? I’m really hoping not but will do if necessary. 😅 thanks!

[@ianpgonzaga]

Hey Elite. You will at least need to run new RCA cables to connect the low line signal from HU to amp. The Bose already has the wiring to each of the speakers but depending on your setup (active x-over or passive x-over) you may also need to run extra speaker wiring. Then depending on your amp you might require a thicker power and ground cable. I'll be doing an amp upgrade soon too but will run the factory speakers and sub. Mine still seem in good condition and already sound decent with the HU I'm running. The amp I've got is a Clarion XC2510. What amp are you looking to use ?

[@eliteculture1519]

@@ianpgonzaga yea that’s what I assumed 😫 I’m picking up. 2 sets of infinity kappa 6.5 component speakers, a Sony gs 4 channel amp and 2 infinity under seat subwoofers since there no space for a sub box. To keep it safe I’ll just take off all the panels and flooring and just add brand new and thicker gauge wires to make sure I get the best outcome. 👌🏽

[@ianpgonzaga]

@@eliteculture1519 ohhh sounds like it's Gunna be a good setup! Let me know how you go - whether or not you end up using the speaker wiring already at the amp or new ones.

[@eliteculture1519]

@@ianpgonzaga hopefully everything goes as planned. But you know how that goes, there’s always a problem 😂 I’ll update you when I finish lmao

How did the Navigation work on theese cars I see that the radio has Nav lines on D plug but cannot understand how were they used This radio doesnt hsve screen big enough to display navigation

[@ianpgonzaga]

Hello! I believe the Navi module was separate to the radio and directions displayed on the instrument cluster screen.

[@Veso266]

@@ianpgonzaga Aha, where did the map display? Or did this navigation work without the map I wonder how did u input the address Also, why did the radio need navigation specific pinout (for audio muting maybe)? I used to use this radio in my Audi A3 (also had Bose), never knew that navigation was even an option The volume broke (known problem when you move the knob and volume jumps like crazy), sadly it was never repaired (I did send the radio to local repairman but he never fixed anything'l, and I sold the car with this broken The buyer didnt care and probably replaced the radio with some aftermarket unit anyway (which is quite sad, since you cant realy add a lot in 1din space anyway, and AUX and Bluetooth could probably be made to work with original radio)

[@nikolaisikes6245]

No map, pretty much just street names and which direction. Also only knows like main roads in any given town. It was very basic.

[@Veso266]

@@nikolaisikes6245 ah ok So how did u input street names? Did navigation module have a separate keyboard Would love to see a video of that, for some reason videos like this are hard to find

[@nikolaisikes6245]

@Veso266 No, you just have a little selector knob and you scroll through the alphabet selecting letters as you go. Selecting a state first, city, then a street name. Again it's all contained within the unit, so it only knows street names of main streets from the year it was made.

[@itsmeRik060]

Is see you have 3 connectors (2black 1red coming from the car and using 1black with power through an iso adapter to the head unit and the other black one with the adapter set for RCA. So what's happens to the other Red one? My radio is now connected through an iso adapter with one red and one black plug from the car. No RCA connected so I think it currently is avoiding the Bose amp( I do have Bose speakers).

[@ianpgonzaga]

Hey rik... The extra red connector is going to the CD stacker. I do talk about it and you can see the pinout for that red plug in the diagrams. Looks like your setup is going through the cd player or stacker somehow instead of the RCA's

[@itsmeRik060]

@@ianpgonzaga ah alright that must be it. I do have the CD stacker. I will figure something out en try to get it to work with the Bose system! Thanks a lot!

[@ianpgonzaga]

@@itsmeRik060 yeah get the adaptor that plugs into the 20 pin plug. That way your sound uses the whole Bose speakers + subwoofer. It actually sounds great with a aftermarket HU that you can boost the bass frequencies (if you like that kind of music)

[@itsmeRik060]

@@ianpgonzaga Yess I will buy the adapter and hope it will sound great! Yeah I hope to get some bass sounds out of it! Because i think at the moment I do not get the full potential of the Bose speakers. Thanks a lot!

[@ianpgonzaga]

@@itsmeRik060 yeah sounds like it might only power the speakers but not they the amp.

[@marcooconnor]

Hey Ian. Great video. Where did you connect the blue amp signal wire to? I got the same harness but unsure where that goes.

[@ianpgonzaga]

Hey. Connected to the ignition live.

[@marcooconnor]

Cheers. Probably a dumb question but did you just take it from the existing wire on the other plug or run a cable from under the steering wheel?

[@ianpgonzaga]

@@marcooconnor nah not dumb at all. There's an ignition switch live at the red plug. If you have a multimeter or test light probe you'll be able to figure out which is the IGN live.
