Re: Upgrade stock 6 speaker system on 2015 JGC Limited

Latest update...

The Alpine SPS-610 component and coaxial combo did not sound good. Even though they were silk dome they were too harsh on the highs, even with setting the HU treble to -6. Mid-bass lacking...

Decided to go with Polk DXI-6501 for front and DB651s for rear. WOW! What a huge difference in sound quality. Silk dome all around and they sound fantastic. Tweeter crossover on front set at -3 and HU treble set to 0. The mids sound fantastic and the coupled with the JL 10" it provides great low end.

Blows away the stock 6 speaker and even the 9 speaker Alpine I has in the 2011 JGC. I can't believe the bass I'm getting with the custom-made box fitting inside the full size spare wheel well. Very easy to make and sure beat the $700 price tag for the Stealthbox.

$1,200 upgrade and very well worth it. Price breakdown as follows:
Front: Polk DXI-6501: $150
Rear: Polk DB651s: $75
Sub: JL Audio 10TW-1: $187
Sub box: (2'x4'x.75" MDF, caulk, etc.): $40
Amp: Alpine PDR-V75: $320
Harness: PAC BCI-CH41: $219
PAC LP7-4 LOC: $38
20' Streetwire 9 conductor wire: (4spkr to and from HU): $ 45
12awg 12' sub wire, speaker terminal, polyfill: $33
4awg amp kit: $25
rca cables: $25
other tools, connectors, etc: $40
Total: $1,197

As mentioned in a previous post, I'm convinced the stock HU cuts mid-bass from the rear speakers. I set the amp to accept input signal from front only and split off the sub input so I could control its gain separately. The LOC is set to max gain. The front gain on amp is set to min, the sub is set to 9 o'clock on the dial (about 20% from min). Using this mix I found the low end kicked in nice at low sound levels. Couldn't achieve without separate sub input off fronts.

Hope this helps anyone considering an upgrade!

Re: Upgrade stock 6 speaker system on 2015 JGC Limited

Quick heads up for anyone looking for a 52-pin harness to tap into the HU audio...

Magnus @ Customtronix will sell just the 52-pin harness for 69euro (currently $74 us). Using this harness you can tap into the factory audio out coming from the HU and then back to the audio leads going to the speakers. This saves you from having to cut into the factory harness. Not a bad price if you want to leave the factory alone.

I'm pretty sure the wiring diagram for the 52-pin is located on wk2jeeps. If not, just search on this forum.

Re: Upgrade stock 6 speaker system on 2015 JGC Limited

I just ordered a 2015 Limited and made sure I got the 9 speaker set up. I'm trading out of my 2011 Laredo X ( which has it )

Re: Upgrade stock 6 speaker system on 2015 JGC Limited

Hey guys, rather than starting a new thread i hope to post the question here. Hope you don’t feel I’m high-jacking the thread!

With 6 speak stock, when maxing our volume i get a lot of static and so forth. Would a speaker upgrade alone resolve this? I don’t think the stock setup is terrible, but does need help as far as clarity. Looking for a simple and cheap solution to this....specially since I’m no longer going to be running my L7 Kicker sub in this vehicle.

Thanks

EDIT:
I guess let me add, do speakers really have to have new mounting hardware? Is there not a way to fit in new speakers into existing slots? I can understand connectors are a different story which is not a problem for me. THanks again.

Re: Upgrade stock 6 speaker system on 2015 JGC Limited

For me there are phases to upgrading the audio system. They build on each other.

Phase 1: upgrade just the stock speakers. You will see an improvement in the stock sound with better speakers but the distortion at higher volume levels was still there for me. The hu onboard amp just can't put out the power, I think it's 18w or less per channel. The full range is decent but very little low end. As 1stjeep has mentioned before, get speakers with a high db sensitivity to handle low power. Cost: $200-500

Phase 2: add an external amp and sub. This will provide a pretty significant bump in quality. If you purchased good speakers then adding a good quality amp and sub will really fill out the sound. The hu is still messing with the output so the signal is not as "clean" as it could be but not noticeable to most people. Cost: $1,000-2,000

Phase 3+: replace the hu (unless you have integrated climate, etc. imbedded in the 8.4 hu) or add a DSP/clean sweep component to clean up the signal. Set up a 5.1 or 7.1 system. Add multiple amps/speakers to fill out the center and rear pillar locations. Will also need to purchase the trim to support the added speakers. Cost: $2-5k?

Re: Upgrade stock 6 speaker system on 2015 JGC Limited

Since the weather here is western NY is still a little too cold to be out messing around in the garage, I still haven't made any changes in my '15 GC's sound system. My intended goals are modest, so I'm not planning any more than speaker upgrades, and still haven't locked in on what speakers I'm going to use.

I know that the tweeters in the "Chrysler Kicker" set up won't fit in the door pods, at least without some serious removal of the mounting ears, and the "Kicker Kickers" have the tweets pre-wired to connect to their provided crossovers, and I don't want to make any major modifications to the wiring harness, in case I ever wanted to return to the stock stuff.

In the rear doors, it appears that the "Chrysler Kickers" are manufactured with 3 mounting ears, which correspond to the doors in some of the Jeeps, but the 2015s aren't mentioned as one of them. I sent an inquiry to one of the Jeep suppliers, asking about this, but so far, haven't gotten a reply.


Nothing is easy anymore.....

Greetings,

I changed mine out for the HAT L3SE. For me, with my setup it was an extreme difference.

IMHO, if you going to change out the speaker, you really need to add amp to it depending on the type of driver you purchase and how loud you want it to play. With an aftermarket amp in the system, you could use the gain controls of each channel as time alignment device. This would simulate it to a certain degree, but again, this method is does not take in the full picture of the rest of the speakers. The fader control is not designed for time alignment.

The other point, even if you just change the speaker out, you might not notice any difference since the settings are fixed with factory DSP/Amp unit.

As for which speaker to choice from, some here use a coaxial, while other like me use what is know as a single wide band full range speaker. Ideally, you do not want anything that has a high (18K hz above) top end. The tweeter that you have in front door and possible ones you have added when you changed out the rear door is more than enough. After all, you do not want to have that ear bleed effect in your head. It it worse on long drives.

Best for now.

Re: Upgrade stock 6 speaker system on 2015 JGC Limited

Thanks for the reply. It's a bummer as i dont have the time or cash to do a full audio upgrade. I was hoping to get a cleaner sound at higher volumes with just a speaker upgrade...


As for the Amp requirement for speak upgrades, isnt that only true if you select speakers with more watt ratings? Its my understanding that when you pruchase speakers with higher watts ratings, it requires more power to drive them which is the reason they wont sound as good or strong. Best to select speakers that match the watts of what your system will put out. Maybe i'm wrong though...

Re: Upgrade stock 6 speaker system on 2015 JGC Limited

anyone have a stock sub box they want to sell? I need one for a small project I want to start on. I don't need the sub, just the box.

Since this comment i've done a lot more research and am beginning to understand why an amp is so much more important when upgrading the speakers. So the biggest issue is the OHM ratings. Seems the standard is 4 ohms for most speakers and if this is the case then the volume is basically half of what the stock speakers offer? How are folks not mentioning this when they talk about their speaker upgrades alone? I find this to be very misleading unless I'm wrong once again about this? I guess the biggest challenge i have with putting a full audio system into a car is running all new speaker wire throughout the car. Not that its a difficult process, but long. Also if i wanted to revert the process it would make things more difficult. Uuggg nothing is freaking simple.

I guess let me add, has anyone found any 2 ohm replacements that make a difference?

EDIT:
OR! Is it because if the sensitivity is 90+ DB, this makes up for the lost of volume? So a speaker with a 93+DB will probably put out the same amount of volume @ 4ohms then one lets say @ 88db @ 2 ohms?

Haha sorry still learning all of this!

You don't have to re-run anything. All of your leads at back at the stock amp. Start from the output harness and extend those speaker leads to your new amp. The actual output of the stock amp should run through a JL clean sweep or Audio processor like that to give you a clean signal to feed your new amp.
