Just wanted to thank you for this amazing video. Never thought id be able to install my own Sub and amp. Took me a few hours but I have zero experience and love the way you broke it down from what wires to splice to tips on how to ground and hide the wires. Thanks again
I watched your video over a dozen times, and two days of trying later and over an hour and a half of trying to stuff a 0ga wire through my firewall gramet, I managed to install a 1600w sub and amp in my '18 impreza. Thank you for the great video as I would've been completely lost without it!
Hey sure thing! Not the easiest of installs, so glad it helped. Cheers!
do you remember how you dealt with the starlink thing?
Yeah, you connect the speaker wires to the rear speaker speakers of your car, at least for me. I don't know if subis ever switch where the connection for starlink is, but you just want to make sure you connect them to the wires not powering starlink
@@ga055 thank you!
Just finished my install, it took the whole day but this video has been my main reference! Thank you so much for the guide! some tips for others:
-you don’t need to remove the seat at all, i have a bigger amp than the one in this video and it fit by sliding the seat forward to place it. wiring the amp is harder though.
-look up video on removing radio, it’s super simple
-if you get stuck, work on something else, and come back later
-you can research and ask questions as much as you want but eventually you j gotta try it yourself
Does anyone know where I can find documentation or diagrams of the radio harness wiring after the installation?
Thanks for this! Saved me a lot of time and hassle.
I’m doing a rear bench delete and have contemplated using some of the dead space below (behind the front two seats) for a box and sub. I was thinking more along the lines of a 10 or maybe two 8’s. What would be your recommendation for that?
Does this apply to the harmon kardon sound system?
Hey I have a 2014 subaru impreza with the DIVX head unit. I was wondering if you or anyone knew if that would be compatible for hooking up a sub? or do I need to get an adapter or head unit?
Where do I tap the line out converter if my Subaru has the starlink sound system
Hey I’m famous! Thanks Chris for the help with the stereo. Sounds amazing!
@@SusanWSucks holding up great! NVX is an awesome brand
Do you know what your alternator is rated at? I'm trying to put about 1300 watts in a 15' Forester but I'm worried about headlight dimming. Any feedback you can give would be appreciated.
Hey Chris,
Loved the vid and I'm looking to do similar. Question though, regarding the component speakers.
I've read the head unit is underpowered and therefore people have run amps to power the component speakers.
How would you tackle this?
Using a different channel on the sub amp, you could attach the fronts for example. But how would you power up the rear components without losing the fade function the head unit provides? Does this require a secondary amp?
Can you use this set up for two subs?
So is the setup using the fronts instead of the rears? Im new to all this and was reffered differently
Great video guy's with a ton of great information.
Why could you not get the signal for the sub amp you need from the amp under the pass seat??
Where did you find the best place to mount the bass knob you were talking about?
how did you figure out what wires to connect to im about to do this in my 2013 subaru Crosstrek xv and it has a different stock radio
Thanks
SUPER THANKS
Hey Chris,
Just curious, how does the sub and amp you used sound? Still enjoying it or are you thinking about replacing any of those components for something better?
Where can I find there wire harness? Any info would be helpful
Can I use this same setup on the WRX
Where did you mount the remote bass button on the front dash?
Hi guys, I have a 21 Crosstrek Limited and have starlink system. Do I need a Telematics 16-pin jumper adapter ??
Because I read that the Telematics module will recognize that the output impedance (which is the front speakers in the OEM configuration) is incorrect and this will flag an error on the Subaru Starlink system.
Thank you very much; thag was helpful. I hope you will upload a video showing the right motion of removing clips without causing stress marks, cosmetic damage, or even breaks. Also, what AWG did you use for the blue wire coming from the battery?
Thank you very much
All parts used we listed in the description on the video. 4 Gauge wiring.
This kit can be used for any subwoofers and amps correct?
Hey! Just did this setup, but I’m not getting a connection. I’ve done a few setups so I assume my problem is I wired wrong to the radio. Do you know what the model of this radio is?
Hello. I have a 2021 Subaru WRX STI. I replaced door speakers. Door speaker wire. And adding a subwoofer. I installed a line output converter after the factory amplifier and it is not working. It turns on but I'm only getting.3 volts out of the RCA cables. I double checked all the speaker wires I tapped into. Does the amp have speaker load censors. Help. Thanks
Awe man ha what are the rear speaker colors
What does instalation like that usually cost
Do u have the wire diagram?
i was wondering if i could get help with installing my line output converter to my 2019 subaru cross trek i wanna make sure i’m doing it right
its been many years since i did car audio installs but you should check out www.the12volt.com . they have many vehicle specific wiring diagrams
Wow I didn't think to use a radio harness to locate the speaker wires for a sub add on. Thanks you saved me on the install on my 2023 Impreza.
What a good job, very practical and simplified installation. I would like to install the Kicher Key 180.4 on my Subaru XV 2019, could you illustrate where I would put it and how would the installation be easier? Do you think it should be behind the radio? How do you do it? Thanks a greeting from Peru.
Did you end up doing this? I'm wondering if i can mount a kicker key behind the radio as well.
@@andytheffboy I already have everything to install the Kicher Key 200 in my Subaru XV, I bought a plug and Play harness in the US, the site at plugnplaykits.com I bought it with everything and the Kicher key since I did not sell it separately, The practical thing about this is to connect everything without cutting cables, or wiring up to the battery, just using the OEM installation, I need to see an issue with the CarPlay in my Subaru, for which they are changing my radio for warranty, once I have The radio will install the Kicher key, I just need to see where I will put the Kicher Key, it seems to me that I will put it in the glove compartment.
Could you please make a video where you make the cable insertion through the firewall clearer? because it’s not clear whether you made a hole or pushed through some space in that grommet. How the tunnel is shaped? Because I want to know the direction to which I should push the wire
Not a personal vehicle but we have a ton of other amp install videos on our channel. Just check out that playlist on our main TH-cam page.
I’m looking to do an amp and speakers/subs in my new 2021 forester. Do I have to ditch the stock radio console?
No. Look up breakout harnesses. They go between the factory harness and the stock radio giving you a place to splice without cutting factory wires. You still get high volume signal attenuation. But unless you are wanting to go deaf, you can make it plenty loud.
Curious about the power wire being zip tied to the speaker wire. Im sure you have a "humming" noise.....
Nope, generally a ground loop issue comes from poor ground or low quality RCA cables. No ground loop issue here.
why on the floor. in the northeast it would get wet
What year Toyota harness did you use? Does that also have rear speaker connections?
Metra 70-1761 to connect to car wiring harness
Metra 71-1761 to connect to factory radio
If you buy both then you don't need to cut any wires on the factory harness and its like $15
I just came across this video. I like the tips on where and how to run the wiring, but I'm horrified that this setup was done without upgrading the negative lead from the chassis to the battery. In the video, it shows you're still using the 10ga (?) wire. Just curious after the number of years this video has been up, has the driver burned through that wire yet?
I found your video searching for the best way to route power through the firewall of my 19 Forester. This is for an amateur radio install. I found the same rubber grommet on the engine side and the plastic housing up above the gas pedal. Looks you poked a small hole in the gasket on the engine side away from the factory wiring? On the under dash side, did you pre drill a hole in the plastic tube housing? I see the blue power wire comes out of a hole but I didn't see an existing hole on my car where the factory wiring comes in by the gas pedal/steering column.
Any solution?
@@nickt1475 Yes, I found a rubber grommet that I cut through. I think it was up behind the gas pedal.
Mike Cooke yeah i made a small cut in the rubber tubing behind the gas pedal and another at the other side where the guy shows in the video he pokes through but I cant get the coat hanger to pass through. Been trying for an hour lol
Why not just run power down drivers side??
Is this amp only powering the sub or is it powering all the speakers in the cabin as well? Looking to do a similar setup but am interested in getting more power to the cabin speakers as well.
Looks like just the sub. Interesting that someone would install a sub with no change to the factory speakers 🤷🏼
Thanks so much for your help! This is an awesome video! Did the radio need an anti theft "factory code" like some manufacturers sometimes require?
I have a 2018 Impreza hatch just like the one in this video and that's something that I'm concerned about.
Would this video work for a 2018 crosstrek sti?
Did you ever find the answer to this question?
Nice video! My friend and I used this video and had a smooth installation. Before the install I noticed as I turn my volume up the bass slowly starts to fade out. After the install the same thing happens with the subwoofer volume. The system seems to fade out the lows at higher volume so the highest I can really listen to it before the sub starts to get quieter is 25. I’m guessing it’s just a weak head unit, but curious if anyone has some input.
Bass roll-off. You can use an Audio Control LC2i to correct that at a decent price.
Provo Beast Audio Installation awesome! I appreciate the info. Thank you.
Rear channel has Bass roll off at about 300 Hz to save the smaller speakers. Front channels should not have that (at least they don't in the 2020 Forester)
interesting i had a car shop put dual subs in the back of my crosstrek recently. i have the rockford upgrade so theres a separate amp for the front speakers too, so the factory amp isnt used. But ive also noticed my bass decreases also around 25. sub has its own amp. did you find a fix for that?
Electrical tape comes apart when hot you should have used heatshrink
Hopefully I’m not commenting too late here. I plan to do a sub install on my girlfriend’s Impreza with the same sub setup I put in my truck. By the end all I ran to my radio was my rcas and my remote signal wire. Will there be a place to plug in my rcas or is that the purpose of the splicing you did? Like you had to make your own rca plugs?
There are harnesses on ebay that should work
Do you know how to enable watching videos when the vehicle is on movement?
Hi pretty new to this, do I need to buy an amplifier or is there anyway I can just use the dials just in my car?
If you are buying a subwoofer, absolutely you will need an amplifier. Your factory radio only puts out about 10 to 15 watts per speaker, and does not have any additional available power for an aftermarket subwoofer.
If you are new to this, i'd recommend just using a loaded enclosure that has the amp and sub all in one. amzn.to/3y5wrlG
@@ProvoBeastAudio thank you!
is there a way to do this without having to splice in to all those wires? like an adapter i can buy or something? lol
yes there is. it's a jumper harness for around $40 so you don't splice into the OEM factory wires. answered my own question
11:25 Can any of these cables be used to disable the lock to watch video while the car is in motion?
You have apparently done this install once or twice! Hahaha!
Not 12mm bolts
I just got a 19 Crosstrek. This won't void any warranties and get me yelled at by the dealership?
Simple answer: no. They have the burden of proving that your stereo install somehow messed up the car.
@@kallmeaznracer well if there's an electric/infotainment issue (which i heard used to be a Subaru problem) or let's say A/C problem,, are you voided?
Hello I’m new to the stereo systems and I was wondering if the output converter would be able to stand two 10”subs
What about a 2016 impreza?

He making me feel out of breath lol
This video is not the best the yellow and black wire this guy used does not work properly leave amp on
The yellow and black wire is to generate an accessory wire (power to the blue / white wire) if needed. Since our factory radio had an analog accessory wire available, we used that instead. Please watch all the video before making a dumb comment.
