Finally Installed my Subwofer ( JL Audio ACP112LG-TW1 ). Took me about 5 hours as this was my first install.
There is access via a grommet from the engine bay. It fit the 8 GA wire easily, but I am not sure if it can fit a 4 GA.
Not much to say about it, pictures show pretty much all you need to know. Hope this helps
Parts I used where:

Panel Removal Tools
Tesa Tape
1/4" Braided Sleeve
Ferrules
Ferrule Crimper
8-gauge amplifier power wiring kit
T-SPEC V8 Mini-ANL Fuses (30A Fuse)
JL Audio ACP112LG-TW1
RCA Cables

The 1/4 ABS Panel I got it from ebay..

Thanks for the guide! Looks great dude, and I bet it sounds even better. You plan on mounting it anywhere, or do you want it to be removable if need be?

That Sucker is so heavy that it won't move from there (plus it fits like a glove)
The JL Sub Connectors are designed to be quick-disconnect , meaning that the [Positive + Ground + Remote Turn on] are all attached to a small "harness" that you can click on and off the sub to allow for easy removal incase I need the space for something unexpected.

So yes it will stay like it is. Sometimes a trip to home depot will require me to leave the sub at home

.

It sound loud, I did not think a small "ported" box like this 12" MicroSub can sound so loud.
Now next will be the stock speakers.. but I'll have to wait till I recover in funds.

Perhaps anyone has a suggestions for door speakers? I am NOT planning on adding a AMP for the door speakers. The Kenwood DDX9905S Head Unit puts out enough for my needs..

are you going to amplify the door/dash speakers?

are you getting any kind of engine noise from the sub? when you press the gas when driving, do you hear a loud pitches whine?

the install looks great!

I didn't see one, but can you attach a picture of that grommet with the power wire through it? i'm curious to see what it looks like now with the power wire inside of it.

No Engine noise or loud pitches from the sub or any speakers..
I'll Snap a picture of the power wire once I get off work and daylight comes out..

that's great! No engine noise means not ground loops. that's good news.

I'm thinking about putting my amp under my seat, the sound processor under the passenger seat, then the subs in the back. I need to measure this weekend to see if i can actually fit the amp. The amp i selected is like 15" x 9" so we'll see!

I'm looking forward to see that grommet picture!

This was the best I could do, not much room to get camera in that area (plus Engine was hot). Hope it helps

Where did you pull power from for the remote lead?

Nice job! Now I have an idea of where to run the wiring.

Since you're in Florida, you don't happen to watch Dean @ Five Star Audio on Youtube??

converter from high to low on the original radio to be

Hi, I'm from Spain and I wanted to ask you for a help. You put a converter from high to low on the original radio to be able to connect the RCA of the Suwoofer. put a converter to take out the rca outputs, because they tell me it won't work. How did you connect it from the radio to the subwoofer? Thank you very much I wait for your answer.

I also did an installation of a subwoofer in my car but the sound is not as clean as I wanted it to be. So I called one of my friends that is very good at this stuff, I don't know why I didn't do this at first but anyway, he came and understood my problem, he started to look in all electronics for like an hour or something until one moment when he touched a cable and understood that there was the problem. To not repeat this terrible experience I decided to buy more qualitative equipment, fortunately, my friend knows about this site 10 Best 5 Channel Amp Reviews 2020 - Beginner Friendly Guide where I found all I needed.

You'll need to make a cut at the engine bay and on the driver side interior (right behind the pedals).

i was able to fit 4ga thru that gommet, but had to wipe outer jacket with wd40 to make slick, and ended up having to tape small screw driver to end of cable to get it thru the inner part of the grommet.
(was very difficult and took several tries) as it was difficult getting it thru the inner seal going in to car

How did you cut the grommet from the inside?
