How to: Install an Amp & Subwoofer in your Audi or Any Make

Hello YT, this is my first video and I hope this helps anyone looking for information on installing an amplifier and subwoofer into an Audi A4 B8 as I couldn’t find information as easy as this video I’ve made for everyone. Thank you for watching!

Camera: IPhone 13
Audio: Rode NT1 USB

Everything you’ll need for the install:

- Multimeter
- Heat gun
- 13 MM/10 MM Socket with 3/8 extension
- PH2/T-30 Driving Bit
- 1/16 & 1/4 Drilling Bit
- Trim prying tool
- 10MM Nut

Subwoofer and AMP setup:

Good tutorial however should really use a line out converter for the best signal. Sending already amplified signal to your low level input on the amp will clip the sub.

I needed this video for the RCA hook up! Great video man! The only difference I had was I had to run my remote wire to the driver side fuse panel. For sum reason my fuse setup in the trunk was a little different. Only had like 3 rows of fuses instead of 4 and they where always all on.

thank you! was able to install my sub and amp 👍

I was an idiot and accidentally wired it so that my stock sub in the trunk got amplified to 1200 watts instead… it took me two days to realize haha but now I have to fix it

Hoping my SQ5 has a similar hookup on the factory subwoofer, I want my 12" CT Sounds Tropo XL bumping on there🤣 thanks for the video

Please tell me that that amp was just for demo purposes you will under power that sub and blow it from amp peaking

What’s the coding on your fog lights i dying to know..

[wilmerlugo]

Hello friend, how are you. A question, what are the fog lights on your car called? and where did you buy them

[taseeusebiu-andrei]

Hi my friend, My audi subwoofer doesn't have the extra pins to attach an external source, where can i attach it instead of that. Thanks in advance

[joelcruz]

You might want to check your polarity. You used the “lettering” wire as Positive when connecting to the factory sub . Then used it as Negative to connect it to the Striped sub in the box.🤔 I always use wires with lines or lettering as Negative.

i want to remove the stock sub and place my own in its place, should i connect the original sub wire to the high or low lever input as my sub supports both, previously i tried wiring it up to the speaker wires before the original amp but had issues where the amp would go into protect mode as soon as the volume is increased but i'm not sure why tho

[marcospozos]

What wire is that you used too connect it too the sub?

[OnekoBlake]

I will like to know if you can install mida range loud speaker with amplifier in A4 also and how will you connect the midrange speakers like you do the sub if it's possible

[byebye]

I am going to be doing this on my Audi, is there any way that I can reach you for questions about how to install carplay?

[justindunn]

So what if we don't have spare wire for connecting to the factory speaker that has that female type connection? just expose the line and wrap it around it? thanks in advance

[ryanbuenconsejo]

Why is the batter in the trunk? You relocated it? Also how did you make your fogs blink like that?

[KingBoxxOfficial]

Hey at the 3 minute mark in the video I see you're connecting the wires to the existing subwoofer....What is the name of that type of connector? And the wires that you used for that? I have my aftermarket subwoofer in a box already and just need to get past that part

[thetruth]

Those fog lights looks cool flashing like that, how did you do it? Any info

[Realityvoidx]

My question is, when connecting the RCA connection from the sub into the hilow converter. Are you disconnecting the sub from the OEM amp?
