I have deadass watched over 20 videos to find the answers to my questions and you somehow managed to answer them in a 6 minute video. Thank you very much sir

[PureTazr]

I must have watched 50 videos on this. All of them never go in detail.

Thank you for this video, short and simple.🎉

[Metalbass]

The add a circuit fuse thing is brilliant and I never knew they existed. Thank you very much for posting this.

I’ve been trying to figure out how to run my remote power without having to tap into my radio or my cigarette lighter and after watching 20+ videos I finally found the solution thank you good sir

[ChaseKelleh]

I'm just getting into car audio and was really not looking forward to pulling out my stock radio just to tap into a wire for the remote wire. That fuse tap is a life saver! Thanks for sharing

[Az-elite]

That circuit adder is the cleanest thing ive seen about adding an amp and sub

[HighVybeTribe]

I rarely see any videos of people running the wire outside and underneath the car to the trunk. Just how's the cable and some split wire loom tubing and you're golden!
This is especially helpful if you're running zero gauge wire or multiple runs of wire

[jonnythompson-unvk]

No hate but the way you explain it sounds like you are doing this for the first time, yet you somehow perfectly explained everything lol

[mhowell]

One of the best simple straight to the point without missing a step videos on adding sub's to the sonata speaker inputs best idea

[joseelgallovelasquez]

I was about to drill a hole into the dash to install a on/off switch but with that add circuit!!! Man I don’t have to deal with that! Thanks for the good pointers man!

[jeko]

Finally a video where someones uncle is not rambling for 60 minutes about a singular fucking wire. Thank you

[JuanRuiz-jvgb]

Three years after you made this video and still helping people!...
You answered my questions in less than 7 minutes 😅
Thank you sir!

[CDashLo]

This is the most informative video with the least amount of time possibly needed ever made to get you right.

[dappergenesis]

This video was more informative then basically every other one I watched. Thanks for the video!

[ColtinCountryman]

I think it's worth mentioning that while this is a quick and easy solution, it may not be the best way to do this to protect your factory speakers, and get the best signal. Your factory head unit is designed to lower the bass frequencies down at higher volumes to protect the factory speakers. This means that your amplifier isn't receiving as strong of a signal as you'd like it too and you may become prone to push your amp beyond what it can handle to compensate. Also, tapping into the speaker outputs in parallel like this means that the head unit now has a lower impedance on it than it usually would have due to a less electrically restrictive path made possible by the circuitry in the amplifier's inputs. It probably won't be a problem in most cases but some factory head units may not be able to handle it.

Using the pre-existing sub as a bypass …. Duly noted : information obtained 😂 thanks man

[danielrodriguez]

I have a challenger that had the opening for a sub and the wire so I added a 8 inch sub it fit perfectly and put a amp on the back of the seat it worked out perfectly and I used your video to figure out the high output level. Looked thur like 6 videos and yours was exactly what I needed!!

[Zetrisy]

this was the most simple, not autistic video / explanation on yt, watched 20 videos atleast to gain knowledge, so thank you sir, kindly 💖

[blackguy-ijij]

I've had several shops swear that this was impossible and I needed to buy an aftermarket head unit in order to get aftermarket subs. I knew it was bullshit

[themindvibez]

This video made a whole lot of sense, this video is the best video I’ve seen hands down an official DYI
