Challenger with the HK sound system, comes with a dual sub box, under the trunk floor. Charger with HK... no dual sub box.

Good news is that the HK Challenger sub box drops right into the 2015+ Charger.

To accomplish this upgrade, I rewired the OEM subs, for an 8 ohm load. This dropped my 400 watt monoblock amp down to a 100 watt output... which is slightly above the rated 75 watt RMS, of the woofers.

:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

Okay... here's the deal. There are 2 dual voice coil woofers. 3 of the voice coils are connected. We will be wiring up all 4 voice coils, to get the proper load.

You'll need:

4 t-taps
4 3.5mm female spade connectors
Some 1/4" shrink tubing, or electrical tape (maybe some friction tape, for the old timers, out there.).
3 feet red 18awg wire.
3 feet black 18awg wire.
NOTE: You won't use all the wire, but it's good to have enough on hand to screw something up & start over.

Series Voice Coil - Parallel Woofer Wiring:

Sub 1 (Left Sub):

VC1:

+ GRN
- WHT


VC2:

+ RED
- TAN


Sub 2 (Right Sub):

VC1:

+ BLU
- YEL

+
-

Using T-Taps, jumper:

Sub1 VC1 GRN to VC2 TAN.

Sub1 VC1 WHT to SUB2 VC2 -.

Sub1 VC2 RED to Sub2 VC1 BLU.

This will net you RED + & WHT - at the connector, to run to the output of the amp.

Disregard all other wires, at the connector. They are already spoken for, inside the box.

Here are my notes:



Here are a few pix, of the woofers and jumpers... showing the wire colors and connectors.



I used an add a circuit, in the rear power distribution block. This is installed at the fuse location that controls the dash power port. In the offset position, this fuse is switched with the ignition. With the fuse inline with the rest of them, it is constantly on. We will install in the offset position (see the picture).



This is the finished product:

HK Dual Sub Box, with Kicker ZX400.1 amp, in a HC Charger.



Oh yes... be sure to get the hold down bolt and nut:

Don’t have a Charger, but looks to be a good Wiki candidate.

Agreed, and I do have a charger with HK. That's a great right up, and great sharing.

Looks great! I'm considering this or perhaps the JBL BassPro Hub.

Yes.

This installation is in my 15 HC with 6 speaker Alpine.

Honestly, if there was room, you could install this, in a Honda.

I was about to comment on the fuse location but then remembered where the battery is!

Looks good and factory. I personally really liked the HK system in my Challenger. It's way better than the HK system in my BMW.

No harness really necessary, for the HK upgrade. Just a couple of jumpers, inside, and re-wire the subs.

It's even easier, if you upgrade the speakers to real subs.

We've done a couple of these upgrades, at my estate, and I've walked quite a few members through it, from this and other forums.

Let me know if you need any help, with this. It's a great upgrade and saves trunk space!

I have one that came out of my 2016 Challenger that was never used. Never turned the radio on and it came out at 1000 miles. I preferred to listen to the engine. 🤓

It ain’t never going back in at this point 😂. I have no idea what would be a fair price. Shipping won’t be cheap. $75 plus FedEx Ground from Utah?
