How do you tap into the signal for the JL?

A line out converter like theL2CI

From the factory sub input, I assume?

Not at all, the line out takes a signal from the rear speakers. In return you can hook up your aftermarket amp to run your subs in your own enclosure.

Is it possible to take the signal from the factory sub input instead of the rear speaker input? I assume there's a lot of low notes that aren't sent to the rear speakers.

I don't think so, generally line out converters take the signal from both left and right rear speakers.

Gotcha, thanks. Just seems like we'll be missing some of the lower notes that way.

Nah you just gotta invest in a good line out converter, it works great with the factory alpine speakers.

But there's no way the factory head unit is sending the lowest notes to the door speakers. I know it would still sound better than the factory sub anyway.

That is a very good point, which is why just replacing the factory sub and using that connections seems like the setup that will yield the best performance

Just incase anyone is interested in what the stock sub looks like in the HK system. I have an early 19 and they had an issue with the box vibrating on the back wall. Thats why you can see the little rubber cut out around the screws...

Plenty of options. AMP Pro lets you add a amp. The others let you replace the factory amp to run your own setup.

Looks like you could yank this out and install something with some more oomph there : )

exactly.. Would love to find something that replaces it and not loose under seat space..

I'm going to replace the factory system with Focal Utopia drivers, A pillar pods, and stealth box with 10's in the back. I just did the same except with one single Utopia 10 in my GT2RS. Sounds amazing.

So just to be clear, I could swap out the factory sub for something aftermarket and there would be no additional equipment needed?

No that's not it at all, you still need a line out converter, wiring kit, and a amp.

Watched some videos on a Wrangler getting a stealthbox to replace the factory alpine unit. Doesn't seem terrible but not as easy as it used to be either.

I'll take a single 10 or 12" JL for mine. It was part of the reason i didnt want the HK stereo knowing id be replacing speakers/sub.

The HK system in my Jeep GC was actually REALLY good. It rattled a bit but overall was really loud and had good bass.
if there was a simple plug and play sub replacement I’d be interested, but I think the HK is good enough that an upgrade isn’t NECESSARY.

Listen to Brownie..... If you're going to intercept the signal at the sub, you'll need to step down the voltage with a line out converter so that you can have an appropriate amplified wattage for the sub/subs you're adding. There are other ways to do it but this is the best, IMO.

The JL Stealthbox is unmatched and I'll respectfully disagree that the provided H/K sub set up is pretty awful. The only one I've seen that's worse is the Sony sub Ford was putting in their premium sound package for years. Now they've changed to a Bang and Olufsun I believe.

I've yet to see another company get as much low end out of a small space as they do.
