Alpine 9 Speaker System, Adding A Subwoofer.....

[Diaz0401]

Ok, I got it somewhat figured out.

Use this to add the aftermarket amplifier.
PAC APSUB-CH41 AmpPRO SUB Wiring Interface

I found out that I don't have ANC in my truck so I'm good, I'm not sure what you would do to bypass it however.

Did this end up working out for you?

Yes it did, it works great!

Can you help me out with figuring out what I need to do to get mine installed lol

Everything you need is in that AmpPRO kit. After you hook it up its just like adding an amp and sub to an aftermarket radio. Super simple.

Cool I ordered it last night the the bypass harness for the ANC

Yep, that's what a lot of folks have done and I think with some success. Not the route I took personally but other folks have. Attached a wiring diagram for the ANC for reference.

What route did you take? Im in the same boat. Does it shut off your amp if you don’t have the ANC disable?

I don't have the Alpine, I have the base 6 which is a lot easier to deal with. I just unplugged the ANC unit's mics (I left it powered just in case it threw codes with it fully unplugged, which it seems from other people's experience is not really a valid concern) and took signal straight from the head unit using a PAC adapter. Good luck with your install!

So I’ve been reading this entire thread and I’m still having trouble getting to the bottom of this issues of adding subs to the Alpine with 8” sub system. Can you help understand, is the AmpPRO kit all I need to add a Skar Audio dual 12” box with 1200 mono amp?

The AmpPro is if you want more line outs, 3 pairs to be exact, the APsub has only one pair of rca’s, mainly to add just a sub.
The AmpPro doesn’t come with the ANC bypass harness, the APSub does.
If just adding a sub/mono signal, the AP sub is the way to go. I have one for sale, just no ANC bypass harness. I upgraded to an AmpPro I purchased used off the Buy and Sell forum. PM me if interested, I’ll let it go for cheap+shipping and all you’ll need is the ANC bypass. Shoots

Interesting - Crutchfield says that's not a fit for my Ram.

So, I finishing my install last night and promised to follow up after I was done. Here's a summary of how it went including some details that I think might benefit someone in the future.

Rant/Initial Review

Overall, the install was easy once I got the correct harness. However, I don't like anything I've heard coming from the JL Audio Stealthbox with the two 10s, powered by the Audio Control LC1.800. I don't know if it's just the nature of a compact subwoofer, or the form fitting box, or the fact that the subs in this box are firing straight into the floor... but this setup just does not fill the cab with balanced sound.. I can hardly hear any bass in the front seats at all - the stock 8" subwoofer filled the cab with more bass than the Stealthbox does. I've tried both phases, so it's not a phase conflict issue. I've tried feeding signals from the L/R rear door channels to the amp, and then I switched to using one of the three signals going to the OEM subwoofer. Not much of a difference between the two signal sources. I can hear nice and full sounding bass if I put my ear right next to the box, but that bass doesn't make it to the front of the cab. I might have to return the Stealthbox and look into the ported boxes from Fox Acoustics if I can't get proper sound out of the JL Audio Stealthbox.

For reference, my expectations are set by the single 12" Kicker Solo-Baric L7 (~700W RMS) that I have in a sealed box in my 4Runner. The JL Audio Stealthbox with it's 800W RMS just doesn't even come close, and for $1500, I expected WAY more.

The good news is that the rest of the Alpine system keeps up very well and actually sounds pretty good when you set the bass to -3 or -4 on the head unit.

Now, onto the install details...

The PAC APH-CH03 is the correct harness to use if you have the Alpine system. Using it allowed me to disable the stock subwoofer behind the rear seat, bypass the ANC (supposedly - I have no way of knowing whether this is working as intended or not), and provide me with an easy place to pull L/R speaker level signals (or the OEM subwoofer signals) to feed my subwoofer amplifier, all from under the drivers seat without having to touch any OEM wiring.

The APH-CH03 harness comes with two male and female "breakout" harnesses that plug into the two grey OEM connectors under the seat. These breakout harnesses allow you to connect the factory speakers to an aftermarket amp, or connect them to the OEM amp. It's a good idea to plug the female grey harness into the male grey OEM harness and tone out which pairs go to which speaker, but here is how mine were mapped in my '19 Rebel. (These are the colors of the PAC APH-CH03 harness):

Speaker 1 (Red)	Front left dash
Speaker 2 (Orange)	Front right dash
Speaker 3 (Yellow)	Front left door
Speaker 4 (Green)	Front right door
Speaker 5 (Blue)	Subwoofer
Speaker 6 (Purple)	Subwoofer
Speaker 7 (Pink)	Subwoofer
Speaker 8 (Light Green)	Front center dash
Speaker 9 (White)	Right rear headboard
Speaker 10 (Gray)	Left rear headboard
Speaker 11 (Brown)	Right rear door
Speaker 12 (Black)	Left rear door

Hello again..I’m currently in the middle of my build waiting on the APH-CH03 harness to come in after that I can complete the wiring. One thing I was wondering was how you disabled the rear subwoofer? As well did you connect all the wires back together in APH harness and tap off one of the subwoofers voice coils to run to a LOC or high level amp? I have a 2021 1500 Big Horn with factory alpine system

The details are a little fuzzy for me as this was a few years ago for me now, but I believe:
When I toned out the wires (see the table in the post you replied to), I identified the three wires that were for the rear subwoofer: blue, purple, pink. I simply did not wire them into the harness, and insulated the ends with a heat-shrink tubing - see pic.

For the signal input to my subwoofer amp, I didn't like the line level input signal, but I don't think I tried using the actual sub signal. The three wires for the stock sub gave me some doubt on the right one to pick. I ended up installing the PAC-APSUB-CH41 to get the pre-amp signal (RCA) right into my amp.

Hello!!!
2020 RAM 1500, 8.4" , 6 speak., no factory amp and sub.
I'm installing a aftermarket amplifier. Where can I get the signal for the "Remote" of the amplifier? From which module or connector?
I've already checked all the connectors near the ANC module and I can't find it.
