Step by Step: 2018 Silverado Amp/Sub Install using the factory radio??

Ended up using an Installbay standard LOC instead of the Pac Audio. I used a mini2 type add a fuse remote turn on signal from the fusebox as well.

Why does everybody take the speaker signal from the rear speakers when they are factory limited to 60% volume roll off by the head unit? Better off using the front to get consistent volume level.

[@FlipSideGarage]

How do you know I always tap at the rear in every vehicle I did?

Technically the best to use is an lc2i,but not everyne want to spend the money.

@@FlipSideGarage I never said that you do this in every vehicle you've ever done because this is the first video i have seen of yours, but at the 8:15 mark in the video you show the drivers side B pillar and plug that you connected to, so in this instance, you did indeed connect to the rear speaker signal wires, which is why i made the statement that everybody i have seen on YT does this and its probably because they dont know about the signal roll off on the rear outputs specifically on GM/Chevy systems. Peace!

So if you are installing a subwoofer and using your factory radio it will be installed using the wires like in your video through the sides and the factory radio doesn’t have to be removed at all right?

Correct.

Where you plugged in your power remote, right beside that 50-amp fuse going towards your firewall there is an exposed male spade connector, from the factory that will take a female spade connector, and its ignition hot only. (directly in front of where you plugged in) I'm getting ready to do this, and I will watch a few videos to pick up the best routes and such that are vehicle specific. Those fuse taps are pretty slick though, but I have to do it this weekend, and someone on another video said that those things could take up to a month to get delivered. Good Thorough video.

He tells you that the Green is positive and and Green/Black is negative… with that said that’s all you need to know. If you’re curious as to what wires on the LOC go to what, the 2 negative wires on the LOC go to the Green/Black and the 2 positive ones go to the Green wire. Different LOC brands use different colors for their wires but all you need to know is which are positive and negative which they all tell you in the instructions.

The flag taps for your LOC work,... but they are notorious for failing. If they work for you great but if they don't, look into the "posi taps".

My wires are different colors and I have seen some guys tap into the wires right by the Bose amp? Thanks.

Good video but I have a question was it the customer that wanted the amp underneath the driver seat? Amp is expose anyone that sits in the back will be stepping on it or worse something getting spilled on it. I have a 2017 Chevy Silverado I installed my amp underneath the backseat there’s plenty of room back there.

[@FlipSideGarage]

Yes. Ive seen people step on amps and no issues. They are made of metal or hard aluminum for a reason. Customer needs the space in the back seat therefore under the seat is the only option.

[@FlipSideGarage]

Most amps are sealed compared to old school amps that have vent holes everywhere. Stepping on it will not hurt the amp one bit.

[@stevetheamerican9919]

Thank you for the video sir.. so at the end of project, what actual wires did you use on the LOC? It doesnt need the power and rem wires used? Just the 4 speaker wires? Thanks again btw for helping people with your time

[@FlipSideGarage]

Correct. I noticed on these that its better to use an actual remote wire from the fusebox compared to the triggered remote wire from loc. The proper way to get signal is to tap onto both rear R and L speakers,but in this case one speaker signal works too. Its also optional to use an Audiocontrol Lc2i signal processor,bit in this case. The customer didnt want to spend the money and juat wants it working. Still works great today.

[@austindifrancesco3350]

So you left the ground and power alone on the inline converter just using power to speaker wire as power to converter ? Missed that in the video

[@venturaac]

I've never used a line-out converter. I'm assuming it is to make it to where the rca's come out?

Yessir. When an OEM radio is present. The aftermarket amp needs a low level signal. The converter converts high signal from door speaker to a low level signal that amp needs.

[@jaydenkettles1862]

From what I understand of that spade, it's more or less for relays for light bars or other bigger accessories. If you notice the spade just above the big 50amp fuse, your add a fuse is covering, that's key on power and protected by the 50amp fuse. If the spade is down and fuse is flipped it's always on power, which also activates all the plugs and 12v receptacles as always on.

[@FlipSideGarage]

@@jaydenkettles1862 the spade is an output. If you run the remote wire straight to it and in an event of a break on the middle. Nothing will pop to save your device. Thats the reason why the add a tap is necessary to prevent issues both in and out.
