2017 Subaru Forester, JL Audio Sub, and Fosgate amp Install 

bro your the man thank you these other videos skip out the main part to hook it up

I completed the install. Took your video for inspiration and put in a Pioneer 200W Bridged amp driving a sealed 10" Sony sub. Just adds so much to the factory system... Thanks once again for daring to do something different to get better sound into our car. Legend.

Omg you've made me so happy seeing you spliced into the stock amp wires. Now I need to see the video of how it sounds

wow. I thought you had to take out the spare tire but it looks like you managed to fit everything in there! very nice! great job dude!

Thank you for the easy to follow instructions. I'm about to do this with my 2016 Touring.

So crazy. My name is also Chad S and I'm trying to install a JL Audio sub in my Subaru Forester. What are the odds? Decided to do it myself just because of this video. Thanks man!

Great video. Installed a similar line converter to my factory system in a 2017 wrx with H/K . I installed my power wire through the firewall. There is an empty grommet behind the dash about the gas pedal. I also did not need a remote wire for my pioneer gm8601. This amp has built in remote turn on through the RCA's.

Your install is excellent, not butchering the car. That make my OCD very happy.

So what about the loss of frequency range? That amp is sending a specific signal to your mids since its tuned for the mids on the channel you tapped. Meaning your sub will not be hitting as low or as high as it could do with a natural full range signal going into your LOC. The problem with these new HK units is they are extremely hard to bypass and get a full signal from the amp. Did you find a way around this or did you just settle? Others tap the sub outputs, you tapped the mids, but no one seems to compare it to a native RCA output of a radio. I'm about to approach this, but everyone is doing it differently, they all say it booms, but all the data shows the sub is being repressed on these factors I mentioned. Being -10 where I'm at I'm trying to get the best way possible so I spend little time in and out of a friends garage fixing things in the car. Installing a TW5 I scored for a killer deal and dont want to handicap this beautiful beastm

looks like the line convertor in parallel is the go for "just adding bass" to the system via an external amp and sub setup.

Yeah thanks man, I just got a 2017 forester xt so this is perfect and looks a lot easier to do then some of the others I’ve seen. I went with the ho wedge. I’d love to see how you did the amp and ground.

Nice clean install! I've got a Sony XAV-AX100 headunit with Infinity Primus components in my 2015 Limited. My sub install will have to be a bit different (no Harman Kardon and I have RCA sub outs, so very straightforward) but I want to do it like yours, with the sub under the cargo area. I was thinking about an underseat unit with an integrated amp but this looks like the better way to go, in terms of quality sub options. Jealous of those lovely brown seats too, lol.

thanks for sharing. Would you please tell me where I can find the Subaru wiring diagram which you show in your video? I have a 2015 Forester XT, and want to make sure I have the correct wiring . thanks again

2011 Subaru legacy 3.6 premium Haram kardon non nav I am looking for a connecter pinouts from the head unit to the factory amp so I can tap into the speaker level rear speakers to install a aftermarket amp and bypass the factory amp but I cannot find a wire diagram any help would be appreciated

Don't seem to have the remote cable on my Harmon kardon factory amp ( 2015 Forester XT)

Did you disconnect the front speakers when you tuned your amp? I’m doing a very similar setup in my 17 Impreza Sport with the factory HK system. I’m trying to figure out if I want to disconnect the front speakers while I tune it...I don’t want to have to take the doors apart but I also don’t want to cut the factory wires at the HK amp. The other consideration I thinking about is how loud to turn up the factory HU when tuning the aftermarket amp I’m adding because I know the factory HU rolls off the bass frequencies at a certain volume level.

Nice video. Where can i find wiring diagram for the subaru outback 2013? i have the harman kardon amp, but i want to know the wiring diagram.

Since you have fiddled with the hardon kardon amp I assume after this. Can you hook up a hideaway 8inch sub straight to that ? I am dumbfounded where you put it. Kind of ingenious. I had a nvx vcw122(1k rms) in way too big a box in my last vehicle. I miss the deep lows , so this brings a new project abound haha.

Nicely done! Informative video. Thank you!

When tapping into the speaker lines, was that before the signal goes into the HK amp? Or are those wires/signals AFTER the amp? I’m doing this exact same install in my 2014 Forester XT next weekend. The only difference is that i opted for a LC2i Pro for the LOC. who knows if ill ever be able to tell the difference, but since i was already spending money on the higher quality amp and sub, I might as well spend more on the LOC too.

I have a 2018 Forester, I can't find out where the entry of that rubber housing is under the dash. If you can enlighten me, that would be great. Been looking for hours.

Why go through all that with the mat covering the sound??

Great video, thank you. Did you change all of the factory speakers? I just replaced all eight in my 2018 Forester XT Touring (looks extraordinarily similar to your car) with speakers I got from Crutchfield, and the sound is much better. However, now I want to replace the Harman Kardon amp with a more powerful unit. Ideally, I would like to lose the mid range speakers in the dashboard and rear doors because they only handle 50 watts and retain the other 4 speakers in the doors because they sound better and handle far more power. I’m worried about losing Starlink functionality if I replace the Harman Kardon amp. (For example, simply disconnecting the speakers in the dashboard will produce a Starlink error message.) I would very much appreciate any ideas from other RU-vidrs. Thank you!

It is spooky watching this video as I have exactly the same colour and model you have minus the Brown leather interior (Australia doesn't get that option). The Drivers position is the only difference I can see.

I have the the same in line converter but which one positive or negative on the box for the rcas they are both the same color

thanks for this, but i have a question. what you doing with the brown wires of the sni-35 ?

Do you do anything with the brown wires on the loc?

Great Video!

Did you not run the power cable through the door grommet because of the thickness? I did a light bar install on my xt and ran the cable through the door grommet. But on my jl audio 12" subwoofer I did it through the same grommet that you did.

Where did you find a wiring diagram I'm looking for one for my vehicle is a 2017 Subaru Impreza

Weird, I'm running 4awg, alpine rated 600, same sub. When I get to 40vol it's like the sub disappears. Not sure if it's ground or bad tune.

did you find any issues with tapping into the say "front speaker wires" in the form of volume/artifacts from the line convertor?

Awesome

This isn't the first time you've done this! haha

Wtf??? 😂
