Alpine amp and sub, Line output converter installation

[static63]

Planning to do this kind of set up as well. When tapping into the oem sub speaker wires to connect to the lc2i pro, do I need to unplug the oem subs or leave them connected it from there on?

You can leave them connected. They will still play normally with the LC2i Pro connected to them.

I am always hesitant about popping out plastic panels on the interior for fear of breaking something. Is there any magic to taking off the lower side panels to access the factory amp, and fuse block?

Watch the oemaudio+ install video and you'll see those side panels come out very easily.

thoughts on swapping the stock subs out for 8” 3 ways to act as more mid bass?? Planning on adding a 10” sub, amp in mine and I’m curious as I have gear sitting

I’m not sure you will be happy installing 8” directly in there place. I’m working on the same thing right now. I’m using Steven audio mb8 8” mid bass for there and building a small enclosure on top of the existing one. Only need .3 cubes.
Then a 10” sub in back corner

Without modifying the stock sub box like Sam is talking about it will be pretty hard to swap out to a traditional 8” sub. It’s just due to the shape and depth of the stock enclosure.

Better off building an enclosure on top to accommodate 3 speakers, 2 for mid bass and one for sub.

How are you attaching the new enclosure to the factory one? What’s easiest way to add the amp? Pre amp harness or something like a Mobridge preamp? Just curious

Mobridge will require a dsp/amp installed as well. If your looking to not change out the factory amp just buy a LOC for your sub signal.

metal is the guy to ask about that. He just got done doing the most intense Supra audio build your date. That I’m aware of
You should look at the sdmi25 for integrating

as for attaching it. I’m not sure yet. Prob a couple rivnuts though.

I used this video to help me remove the fuse box and find the wire I needed which ended up being a green/blue wire for the input wire into my relay:



Here is how I wired the relay:

87- Output to the LOC (this goes into the remote in port on the LC2i)
30- 12v constant (this went to my distribution block pictured earlier)
86- This goes to the green/blue wire that is from the fuse box
85- Ground

Been looking for this info for a while! Does this make it so that the 12v comes one only when the car is turned on and turns off when the car is off, just like the video? What kind of relay do I need? Just a generic one? And what's the best way to tap into the green/blue wire? Would just a Posi-tap work?

It does make it so it comes on and off with the ignition. Use a basic 5 pin relay. I typically strip the oem wire and solder and tape in my connections. Taps work. It really is just personal preference not right or wrong.

Here is a link to a basic relay like I used:

Yea I stopped by AutoZone last night and picked one up. Worked like a charm. Been looking for a 12v power source that would cut off with the engine. Saw the YouTube video but no real directions on the relay part so I didn't want to screw something up.

I am currently doing the same thing as far as putting a LOC (Kicker 46KISLOC2) in the wifes 2021 Supra GR and what a nightmare. So my question is do you need a relay into tap into the fuse panel or can I just tap in with the remote wire from the LOC. The Kicker 46KISLOC2 remote wire is the signal (remote) and power to the amp. I'm not understanding the relay unless its just for safety purposes. Another question which color wires did you use on the relay to tap into the fuse panel? Some further instruction on using a relay like you said and the video but what goes to what?

The relay is so you aren't drawing anything away from the circuit that the OEM wire is operating. You are essentially using the voltage or ground input to "trigger" the relay without affecting that circuit.

Do not pay attention to wire colors on the pigtail of the wire because some relay pigtails can use different colors for different pins. Pay attention to the numbers on the relay and wire those accordingly:

87- Output to the LOC (this goes into the remote in port on the LC2i or in your case, the remote wire to the kicker)
30- 12v constant (this went to my distribution block pictured earlier)
86- This goes to the green/blue wire that is from the fuse box
85- Ground

Hopefully this helps.
